This is the Developer Changelog for Piwik platform developers. All changes in our HTTP API's, Plugins, Themes, SDKs, etc. are listed below.

The Product Changelog at piwik.org/changelog lets you see more details about any Piwik release, such as the list of new guides and FAQs, security fixes, and links to all closed issues.

Piwik 3.0.5

New APIs

  • The events ScheduledTasks.shouldExecuteTask, ScheduledTasks.execute, ScheduledTasks.execute.end have been added to customize the behaviour of scheduled tasks.
  • A new event CustomPiwikJs.shouldAddTrackerFile has been added to let plugins customize which tracker files should be included in piwik.js JavaScript tracker
  • A new event Login.authenticate.successful has been added, which is triggered when a user successful signs in
  • A new API class Piwik\Plugins\CustomPiwikJs\TrackerUpdater has been added to update the piwik.js JavaScript tracker

New commands

  • The commands plugin:activate and plugin:deactivate can now activate and deactivate multiple plugins at once

Piwik 3.0.4

New APIs

  • A new event Db.getActionReferenceColumnsByTable has been added in case a plugin defines a custom log table which references data to the log_action table
  • The event System.addSystemSummaryItems and System.filterSystemSummaryItems have been added so plugins can add items and filter items of the system summary widget
  • A new JavaScript tracker method getPiwikUrl has been added to retrieve the URL of where the Piwik instance is located
  • A new JavaScript tracker method getCurrentUrl has been added to retrieve the current URL of the website.
  • A new JavaScript tracker method getNumTrackedPageViews has been added to retrieve the number of tracked page views within the currently loaded page or web application.
  • New JavaScript tracker methods setSessionCookie, getCookie, hasCookies, getCookieDomain, getCookiePath, and getSessionCookieTimeout have been added for better cookie support in plugins.
  • email and url form fields can now be used in settings.

Piwik 3.0.3

Breaking Changes

  • New config setting enable_plugin_upload lets you enable uploading and installing a Piwik plugin ZIP file by a Super User. This used to be enabled by default, but it is now disabled by default now for security reasons.
  • New Report class property Report::$supportsFlatten lets you define if a report supports flattening (defaults to true). If set to false it will also set ViewDataTable\Config::$show_flatten_table to false

New APIs

  • A new event Controller.triggerAdminNotifications has been added to let plugins know when they are supposed to trigger notifications in the admin.

Library updates

  • pChart library has been removed in favor of CpChart, a pChart fork with composer support and PSR standards.

Piwik 3.0.2

New Features

  • A new SMS provider for sms reports has been added: ASPSMS.com

New APIs

  • The JavaScript Tracker now supports CrossDomain tracking. The following tracker methods were added for this: enableCrossDomainLinking, disableCrossDomainLinking, isCrossDomainLinkingEnabled
  • Added JavaScript Tracker method getLinkTrackingTimer to get the value of the configured link tracking time
  • Added JavaScript Tracker method deleteCustomVariables to delete all custom variables within a certain scope
  • The method enableLinkTracking can now be called several times to make Piwik aware of newly added links when your DOM changes
  • Added a new method Piwik\Plugin\Report::getMetricNamesToProcessReportTotals() that lets you define which metrics should show percentages in the table report visualization on hover. If defined, these percentages will be automatically calculated.
  • The event Tracker.newConversionInformation now posts a new fourth parameter $action
  • New HTTP API method UserCountry.getCountryCodeMapping to get a list of used country codes to country names

Changes

  • SMS provider now can define their credential fields by overwriting getCredentialFields(). This allows to have SMS providers that require more than only an API key.
  • Therefore the MobileMessaging API method setSMSAPICredential() now takes the second parameter as an array filled with credentials (instead of a string containing an API key)

Piwik 3.0.1

New APIs

  • Live API responses now return a new field ‘generationTimeMilliseconds’ (the generation time for this page, in milliseconds) which is internally used to process the Average generation time in the Visitor Profile
  • Added new event MultiSites.filterRowsForTotalsCalculation to filter which sites will be included in the All Websites Dashboard totals calculation.
  • The method Piwik\Plugin\Archiver::shouldRunEvenWhenNoVisits() has been added. By overwriting this method and returning true, a plugin archiver can force the archiving to run even when there was no visit for the website/date/period/segment combination (by default, archivers are skipped when there is no visit).

Piwik 3.0.0

New guide

Read more about migrating a plugin from Piwik 2.X to Piwik 3 in our Migration guide.

Breaking Changes

  • When using the Piwik JavaScript Tracking via _paq.push, it is now required to configure the tracker (eg calling setSiteId and setTrackerUrl) before the piwik.js JavaScript tracker is loaded to ensure the tracker works correctly. If the tracker is not initialised correctly, the browser console will display the error "_paq.push() was used but Piwik tracker was not initialized before the piwik.js file was loaded. [...]"

  • The UserManager API methods do no longer return any token_auth properties when requesting a user

  • The menu classes Piwik\Menu\MenuReporting and Piwik\Menu\MenuMain have been removed

  • The class Piwik\Plugin\Widgets has been removed and replaced by Piwik\Widget\Widget. For each widget one class is needed from now on. You can generate a widget via ./console generate:widget.

  • The class Piwik\WidgetList class has been moved to Piwik\Widget\WidgetsList.

  • The method Piwik\Plugins\API\API::getLastDate() has been removed.

  • The method Piwik\Archive::getDataTableFromArchive() has been removed, use Piwik\Archive::createDataTableFromArchive instead.

  • The method Piwik\Plugin\Menu::configureReportingMenu has been removed. To add something to the reporting menu you need to create widgets

  • The method Report::configureWidget(), Report::getWidgetTitle() and Report::configureReportingMenu() have been removed, use the new method Report::configureWidgets() instead.

  • The method Report::getCategory() has been moved to Report::getCategoryId() and does no longer return the translated category but the translation key of the category.

  • The property Report::$category has been renamed to Report::$categoryId

  • The methods Report::factory(), Report::getAllReportClasses(), Report::getAllReports have been moved to the Piwik\Plugin\Reports class.

  • The properties Report::$widgetTitle, Report::$widgetParams and Report::$menuTitle were removed, use the method Report::configureWidgets() to create widgets instead

  • In the HTTP API methods Dashboard.getDefaultDashboard and Dashboard.getUserDashboards we do no longer remove not existing widgets as it is up to the client which widgets actually exist

  • The method Piwik\Plugin\Controller::getEvolutionHtml has been removed without a replacement as it should be no longer needed. The evolution is generated by ViewDataTables directly

  • The core:plugin console command has been removed in favor of the new plugin:list, plugin:activate and plugin:deactivate commands as announced in Piwik 2.11

  • The visibility of private properties and methods in Piwik\Plugins\Login\Controller were changed to protected

  • Controller actions are now case sensitive. This means the URL and events have to use the same case as the name of the action defined in a controller.

  • When calling the HTTP Reporting API, a default filter limit of 100 is now always applied. The default filter limit used to be not applied to API calls that do not return reports, such as when requesting sites, users or goals information.

  • The "User Menu" was removed and should be replaced by "Admin Menu". Change configureUserMenu(MenuUser $menu) to configureAdminMenu(MenuAdmin $menu) in your Menu.php.

  • The method Piwik\Menu\MenuAbstract::add() has been removed, use Piwik\Menu\MenuAbstract::addItem() instead

  • The method Piwik\Menu\MenuAdmin::addSettingsItem() was removed, use Piwik\Menu\MenuAdmin::addSystemItem() instead.

  • A new methd Piwik\Menu\MenuAdmin::addMeasurablesItem() was added.

  • The class Piwik\Plugin\Settings has been splitted to Piwik\Settings\Plugin\SystemSettings and Piwik\Settings\Plugin\UserSettings.

  • The creation of settings has slightly changed to improve performance. It is now possible to create new settings via the method $this->makeSetting() see Piwik\Plugins\ExampleSettingsPlugin\SystemSettings for an example.

  • It is no longer possible to define an introduction text for settings.

  • If requesting multipe periods for one report, the keys that define the range are no longer translated. For example before 3.0 an API response may contain: <result date="From 2010-02-01 to 2010-02-07"> which is now <result date="2010-02-01,2010-02-07">.

  • The following deprecated events have been removed as mentioned.

  • Tracker.existingVisitInformation Use dimensions instead of using Tracker events.

  • Tracker.newVisitorInformation

  • Tracker.recordAction

  • Tracker.recordEcommerceGoal

  • Tracker.recordStandardGoals

  • ViewDataTable.getDefaultType Specify the default type in a Report instead

  • Login.authenticate Create a custom SessionInitializer instead of using Login events

  • Login.initSession.end

  • Login.authenticate.successful

  • When posting one of the events API.Request.dispatch, API.Request.dispatch.end, API.$plugin.$apiAction, or API.$plugin.$apiAction.end the $finalParameters parameter is indexed in Piwik 2 (eg array(1, 6)), and named in Piwik 3 (eg array('idSite' => 1, 'idGoal' => 6))

  • Widgets using the already removed UserSettings plugin won't work any longer. Please update the module and action parameter in the widget url according to the following list

    old module old action new module new action
    UserSettings getPlugin DevicePlugins getPlugin
    UserSettings index DevicesDetection software
    UserSettings getBrowser DevicesDetection getBrowsers

Read more about migrating a plugin from Piwik 2.X to Piwik 3 on our Migration guide.

Deprecations

  • The method Piwik\Updates::getMigrationQueries() has been deprecated and renamed to getMigrations(). It is still supported to use the method, but the method will be removed in Piwik 4.0.0
  • The method Piwik\Updater::executeMigrationQueries() has been deprecated and renamed to executeMigrations. It is still supported to use the method, but the method will be removed in Piwik 4.0.0.

New APIs

  • Multiple widgets for one report can now be created via the Report::configureWidgets() method via the new classes Piwik\Widget\ReportWidgetFactory and Piwik\Widget\ReportWidgetConfig
  • There is a new property Report::$subCategory that lets you add a report to the reporting UI. If a page having that name does not exist yet, it will be created automatically. The newly added method Report::getSubCategory() lets you get this value.

  • New HTTP API method API.getReportPagesMetadata to get a list of all available pages that exist including the widgets they include
  • New HTTP API method SitesManager.getSiteSettings to get a list of all available settings for a specific site
  • The JavaScript AjaxHelper has a new method ajaxHelper.withTokenInUrl() to easily send a token along a XHR. Within the Controller the existence of this token can be checked via $this->checkTokenInUrl(); to prevent CSRF attacks.
  • The new class Piwik\Updater\Migration\Factory lets you easily create migrations that can be executed during an update. For example database or plugin related migrations. To generate a new update with migrations execute ./console generate:update.
  • The new method Piwik\Updater::executeMigration lets you execute a single migration.
  • The new method Piwik\Segment::willBeArchived lets you detect whether a segment will be archived or not.
  • The following events have been added:
  • ViewDataTable.filterViewDataTable lets you filter available visualizations
  • Dimension.addDimension lets you add custom dimensions
  • Dimension.filterDimension lets you filter any dimensions
  • Report.addReports lets you add dynamically created reports

  • PluginManager.pluginUninstalled triggered after a plugin was uninstalled
  • Updater.componentInstalled triggered after a component was installed
  • Updater.componentUninstalled triggered after a component was uninstalled
  • New HTTP Tracking API parameter pv_id which accepts a six character unique ID that identifies which actions were performed on a specific page view. Read more about it in the HTTP Tracking API;
  • New event Segment.addSegments that lets you add segments.
  • New Piwik JavaScript Tracker method disableHeartBeatTimer() to disable the heartbeat timer if it was previously enabled.
  • The SitesManager.getJavascriptTag has a new option getJavascriptTag to enable the tracking of users that have JavaScript disabled

Changes

  • New now accept tracking requests for up to 1 day in the past instead of only 4 hours
  • If a tracking request has a custom timestamp that is older than one day and the tracking request is not authenticated, we ignore the whole tracking request instead of ignoring the custom timestamp and still tracking the request with the current timestamp

New features

  • Piwik JavaScript Tracking API: we now attempt to track Downloads and Outlinks when the user uses the mouse middle click or the mouse right right click. Previously only left clicks on Downloads and Outlinks were measured.
  • New "Sparklines" visualization that lets you create a widget showing multiple sparklines.
  • New config.ini.php setting: tracking_requests_require_authentication_when_custom_timestamp_newer_than to change how far back Piwik will track your requests without authentication. By default, value is set to 86400 (one day). The configured value is in seconds.

Library updates

  • Updated AngularJS from 1.2.28 to 1.4.3
  • Updated several backend libraries to their latest version: doctrine/cache, php-di.

Internal change

  • Support for IE8 was dropped. This affects only the Piwik UI, not the Piwik.js Tracker.
  • Required PHP version was increased from 5.3 to 5.5.9
  • We have updated PhantomJS 1.9 to 2.1.1 for our UI screenshot tests.

Piwik 2.16.3

New APIs

  • The Piwik JavaScript tracker has a new method trackRequest that allows you to send any tracking parameters to Piwik. For example _paq.push(['trackRequest', 'te=foo&bar=baz'])

Internal Changes

  • Expected screenshots for UI tests are now stored using Git LFS instead of a submodule. Running, creating or updating UI tests will require Git LFS to be installed. The folder containing expected screenshots was renamed from expected-ui-screenshots to expected-screenshots. The UI-Test-Runner is now able to handle both names.

Piwik 2.16.2

New APIs

  • Multiple JavaScript trackers can now be created easily via _paq.push(['addTracker', piwikUrl, piwikSiteId]). All tracking requests will be then sent to all added Piwik trackers. Learn more.
  • It is possible to get an asynchronously created tracker instance (addTracker) via the method Piwik.getAsyncTracker(optionalPiwikUrl, optionalPiwikSiteId). This allows you to get the tracker instance and to send different tracking requests to this Piwik instance and to configure it differently than other tracker instances.
  • Added a new API method Goals.getGoal($idSite, $idGoal) to fetch a single goal.

Internal change

  • Piwik is now compatible with PHP7.
  • piwik.js, if you call the method setDomains note that that the behavior has slightly changed. The current page domain (hostname) will now be added automatically if none of the given host alias passed as a parameter to setDomains contain a path and if no host alias is already given for the current host alias. Say you are on "example.org" and set hostAlias = ['example.com', 'example.org/test'] then the current "example.org" domain will not be added as there is already a more restrictive hostAlias 'example.org/test' given. We also do not add the current page domain (hostname) automatically if there was any other host specifying any path such as ['example.com', 'example2.com/test']. In this case we also do not add the current page domain "example.org" automatically as the "path" feature is used. As soon as someone uses the path feature, for Piwik JS Tracker to work correctly in all cases, one needs to specify all hosts manually. Learn more.
  • piwik.js: after an ecommerce order is tracked using trackEcommerceOrder, the items in the cart will now be removed from the JavaScript object. Calling trackEcommerceCartUpdate will not remove the items in the cart.

Piwik 2.16.1

New features

  • New method setIsWritableByCurrentUser for SystemSetting to change the writable permission for certain system settings via DI.
  • JS Tracker: setDomains function now supports page wildcards matching eg. example.com/index* which can be useful when tracking a group of pages within a domain in a separate website in Piwik
  • To customise the list of URL query parameters to be removed from your URLs, you can now define and overwrite url_query_parameter_to_exclude_from_url INI setting in your config.ini.php file. By default, the following query string parameters will be removed: gclid, fb_xd_fragment, fb_comment_id, phpsessid, jsessionid, sessionid, aspsessionid, doing_wp_cron, sid.

Deprecations

  • The following PHP functions have been deprecated and will be removed in Piwik 3.0:
  • SettingsServer::isApache()

New guides

Breaking Changes

  • Reporting API: when a cell value in a CSV or TSV (excel) data export starts with a character =, - or +, Piwik will now prefix the value with ' to ensure that it is displayed correctly in Excel or OpenOffice/LibreOffice.

Internal change

  • Tracking API: by default, when tracking a Page URL, Piwik will now remove the URL query string parameter sid if it is found.
  • In the JavaScript tracker, the function setDomains will not anymore attempt to set a cookie path. Learn more about configuring the tracker correctly when tracking one or several domains and/or paths.

Piwik 2.16.1

Internal change

  • The setting [General]enable_marketplace=0/1 was removed, instead the new plugin Marketplace can be disabled/enabled. The updater should automatically migrate an existing setting.

Piwik 2.16.0

New features

  • New segment actionType lets you segment all actions of a given type, eg. actionType==events or actionType==downloads. Action types values are: pageviews, contents, sitesearches, events, outlinks, downloads
  • New segment actionUrl lets you segment any action that matches a given URL, whether they are Pageviews, Site searches, Contents, Downloads or Events.
  • New segment deviceBrand lets you restrict your users to those using a particular device brand such as Apple, Samsung, LG, Google, Nokia, Sony, Lenovo, Alcatel, etc. View the complete list of device brands.
  • New segment operators =^ "Starts with" and =$ "Ends with" complement the existing segment operators: Contains, Does not contain, Equals, Not equals, Greater than or equal to, Less than or equal to.
  • The JavaScript Tracker method PiwikTracker.setDomains() can now handle paths. This means when setting eg _paq.push(['setDomains, '*.piwik.org/website1']) all link that goes to the same domain piwik.org but to any other path than website1/* will be treated as outlink.
  • In Administration > Websites, for each website, there is a checkbox "Only track visits and actions when the action URL starts with one of the above URLs". In Piwik 2.14.0, any action URL starting with one of the Alias URLs or starting with a subdomain of the Alias URL would be tracked. As of Piwik 2.15.0, when this checkbox is enabled, it may track less data: action URLs on an Alias URL subdomain will not be tracked anymore (you must specify each sub-domain as Alias URL).
  • It is now possible to pass an option php-cli-options to the core:archive command. The given cli options will be forwarded to the actual PHP command. This allows to for example specifiy a different memory limit for the archiving process like this: ./console core:archive --php-cli-options="-d memory_limit=8G"
  • New less variable @theme-color-menu-contrast-textSelected that lets you specify the color of a selected menu item.
  • in Administration > Diagnostics, there is a new page Config file which lets Super User view all config values from global.ini.php in the UI, and whether they were overriden in your config/config.ini.php

New commands

  • New command config:set lets you set INI config options from the command line. This command can be used for convenience or for automation.

Internal changes

  • UsersManager.* API calls: when an API request specifies a token_auth of a user with admin permission, the returned dataset will not include all usernames as previously, API will now only return usernames for users with view or admin permission to website(s) viewable by this token_auth.
  • When generating a new plugin skeleton via generate:plugin command, plugin name must now contain only letters and numbers.
  • JavaScript Tracker tests no longer require SQLite. The existing MySQL configuration for tests is used now. In order to run the tests make sure Piwik is installed and [database_tests] is configured in config/config.ini.php.
  • The definitions for search engine and social network detection have been moved from bundled data files to a separate package (see https://github.com/piwik/searchengine-and-social-list).
  • In UI screenshot tests, a test environment configOverride setting should be no longer overwritten. Instead new values should be added to the existing configOverride array in PHP or JavaScript. For example instead of testEnvironment.configOverride = {group: {name: 1}} use testEnvironment.overrideConfig('group', 'name', '1').

New APIs

  • Add your own SMS/Text provider by creating a new class in the SMSProvider directory of your plugin. The class has to extend Piwik\Plugins\MobileMessaging\SMSProvider and implement the required methods.
  • Segments can now be composed by a union of multiple segments. To do this set an array of segments that shall be used for that segment $segment->setUnionOfSegments(array('outlinkUrl', 'downloadUrl')) instead of defining a SQL column.

Deprecations

  • The method DB::tableExists was un-used and has been removed.

Piwik 2.15.0

New commands

  • New command diagnostics:analyze-archive-table that analyzes archive tables
  • New command database:optimize-archive-tables to optimize archive tables and possibly save disk space (even if on InnoDB)
  • New Command core:invalidate-report-data to invalidate archive data (w/ period cascading) (FAQ)

New APIs and features

  • Piwik 2.15.0 is now mostly compatible with PHP7.
  • The JavaScript Tracker piwik.js got a new method logAllContentBlocksOnPage to log all found content blocks within a page to the console. This is useful to debug / test content tracking. It can be triggered via _paq.push(['logAllContentBlocksOnPage'])
  • The Class Piwik\Plugins\Login\Controller is now considered a public API.
  • The new method Piwik\Menu\MenuAbstract::registerMenuIcon() can be used to define an icon for a menu category to replace the default arrow icon.
  • New event CronArchive.getIdSitesNotUsingTracker that allows you to set a list of idSites that do not use the Tracker API to make sure we archive these sites if needed.
  • New events CronArchive.init.start which is triggered when the CLI archiver starts and CronArchive.end when the archiver ended.
  • Piwik tracker can now be configured with strict Content Security Policy (CSP FAQ).
  • Super Users can choose whether to use the latest stable release or latest Long Term Support release.

Breaking Changes

  • The method Dimension::getId() has been set as final. It is not allowed to overwrite this method.
  • We fixed a bug where the API method Sites.getPatternMatchSites only returned a very limited number of websites by default. We now return all websites by default unless a limit is specified specifically.
  • Handling of localized date, time and range formats has been changed. Patterns no longer contain placeholders like %shortDay%, but work with CLDR pattern instead. You can use one of the predefined format constants in Date class for using getLocalized().
  • As we are now using CLDR formats for all languages, some time formats were even changed in english. Attributes like prettyDate in API responses might so have been changed slightly.
  • The config enable_measure_piwik_usage_in_idsite which is used to track the Piwik usage with Piwik was removed and replaced by a new plugin AnonymousPiwikUsageMeasurement

Deprecations

  • The following HTTP API methods have been deprecated and will be removed in Piwik 3.0:
  • SitesManager.getSitesIdWithVisits
  • API.getLastDate
  • The following events have been deprecated and will be removed in Piwik 3.0. Use dimensions instead.
  • Tracker.existingVisitInformation
  • Tracker.getVisitFieldsToPersist
  • Tracker.newConversionInformation
  • Tracker.newVisitorInformation
  • Tracker.recordAction
  • Tracker.recordEcommerceGoal
  • Tracker.recordStandardGoals
  • The Platform API method \Piwik\Plugin::getListHooksRegistered() has been deprecated and will be removed in Piwik 4.0. Use \Piwik\Plugin::registerEvents() instead.

Internal changes

  • When logging in, the username is now case insensitive
  • URLs with emojis and any other unicode character will be tracked, with special characters replaced with �
  • A permanent warning notification is now displayed when PHP is 5.4.* or older, since it has reached End Of Life
  • In piwik.js we replaced JSON2 with JSON3 to implement CSP (Content Security Policy) as JSON3 does not use eval(). JSON3 will be used if a browser does not provide a native JSON API. We are using JSON3 in a way that it will not conflict if your website is using JSON3 as well.
  • The option branch of the console command development:sync-system-test-processed was removed as it is no longer needed.
  • All numbers in reports will now appear formatted (eg. 1,000,000 instead of 1000000)
  • Database connections now use UTF-8 charset explicitely to force UTF-8 data handling

Piwik 2.14.0

Breaking Changes

  • The UserSettings API has been removed. The API was deprecated in earlier versions. Use DevicesDetection, Resolution and DevicePlugins API instead.
  • Many translations have been moved to the new Intl plugin. Most of them will still work, but please update their usage. See matomo-org#8101 for a full list

New features

  • The JavaScript Tracker does now track outlinks and downloads if a user opens the context menu if the enabled parameter of the enableLinkTracking() method is set to true. To use this new feature use tracker.enableLinkTracking(true) or _paq.push(['enableLinkTracking', true]);. This is not industry standard and is vulnerable to false positives since not every user will select "Open in a new tab" when the context menu is shown. Most users will do though and it will lead to more accurate results in most cases.
  • The JavaScript Tracker now contains the 'heart beat' feature which can be used to obtain more accurate visit lengths by periodically sending 'ping' requests to Piwik. To use this feature use tracker.enableHeartBeatTimer(); or _paq.push(['enableHeartBeatTimer']);. By default, a ping request will be sent every 15 seconds. You can specify a custom ping delay (in seconds) by passing an argument, eg, tracker.enableHeartBeatTimer(10); or _paq.push(['enableHeartBeatTimer', 10]);.
  • New custom segment languageCode that lets you segment visitors that are using a particular language. Example values: de, fr, en-gb, zh-cn, etc.
  • Segment userId now supports any segment operator (previously only operator Contains =@ was supported for this segment).

Commands updates

  • The command core:archive now has two new parameter: --force-idsegments and --skip-idsegments that let you force (or skip) processing archives for one or several custom segments.
  • The command scheduled-tasks:run now has an argument task that lets you force run a particular scheduled task.

Library updates

  • Updated pChart library from 2.1.3 to 2.1.4. The files were moved from the directory libs/pChart2.1.3 to libs/pChart

Internal change

  • To execute UI tests "ImageMagick" is now required.
  • The Q JavaScript promise library is now distributed with tests and can be used in the piwik.js tests.

Piwik 2.13.0

Breaking Changes

  • The API method Live.getLastVisitsDetails does no longer support the API parameter filter_sort_column to prevent possible memory issues when filter_offset is large.
  • The Event Site.setSite was removed as it causes performance problems.
  • piwik.php does now return a HTTP 400 (Bad request) if requested without any tracking parameters (GET/POST). If you still want to use piwik.php for checks please use piwik.php?rec=0.

Deprecations

  • The method Piwik\Archive::getBlob() has been deprecated and will be removed from June 1st 2015. Use one of the methods getDataTable*() methods instead.
  • The API parameter countVisitorsToFetch of the API method Live.getLastVisitsDetails has been deprecated as filter_offset and filter_limit work correctly now.

New commands

  • There is now a diagnostic:run command to run the system check from the command line.
  • There is now an option --xhprof that can be used with any command to profile that command via XHProf.

APIs Improvements

  • Visitor details now additionally contain: deviceTypeIcon, deviceBrand and deviceModel
  • In 2.6.0 we added the possibility to use filter_limit and filter_offset if an API returns an indexed array. This was not working in all cases and is fixed now.
  • The API parameter filter_pattern and filter_offset[] can now be used if an API returns an indexed array.

Internal changes

Piwik 2.12.0

Breaking Changes

  • The deprecated method Period::factory() has been removed. Use Period\Factory instead.
  • The deprecated method Config::getConfigSuperUserForBackwardCompatibility() has been removed.
  • The deprecated methods MenuAdmin::addEntry() and MenuAdmin::removeEntry() have been removed. Use Piwik\Plugin\Menu instead.
  • The deprecated methods MenuTop::addEntry() and MenuTop::removeEntry() have been removed. Use Piwik\Plugin\Menu instead.
  • The deprecated method SettingsPiwik::rewriteTmpPathWithInstanceId() has been removed.
  • The following deprecated methods from the Piwik\IP class have been removed, use Piwik\Network\IP instead:
    • sanitizeIp()
    • sanitizeIpRange()
    • P2N()
    • N2P()
    • prettyPrint()
    • isIPv4()
    • long2ip()
    • isIPv6()
    • isMappedIPv4()
    • getIPv4FromMappedIPv6()
    • getIpsForRange()
    • isIpInRange()
    • getHostByAddr()

Deprecations

  • API classes should no longer have a protected constructor. Classes with a protected constructor will generate a notice in the logs and should expose a public constructor instead.
  • Update classes should not declare static getSql() and update() methods anymore. It is still supported to use those, but developers should instead override the Updates::getMigrationQueries() and Updates::doUpdate() instance methods.

New features

  • The method Piwik\Log::getLogLevel() has been deprecated

Piwik 2.9.1

Breaking Changes

  • The HTTP Tracker API does now respond with a HTTP 400 instead of a HTTP 500 in case an invalid idsite is used

New APIs

  • New URL parameter send_image=0 in the HTTP Tracking API to receive a HTTP 204 response code instead of a GIF image. This improves performance and can fix errors if images are not allowed to be obtained directly (eg Chrome Apps).

New commands

  • core:plugin list lists all plugins currently activated in Piwik.

Piwik 2.9.0

Breaking Changes

  • Development related console commands are only available if the development mode is enabled. To enable the development mode execute ./console development:enable.
  • The command php console core:update does no longer have a parameter --dry-run. A dry run is now executed by default followed by a question whether one actually wants to execute the updates. To skip this confirmation step one can use the --yes option.

Deprecations

  • Most methods of Piwik\IP have been deprecated in favor of the new piwik/network component.
  • The file tests/PHPUnit/phpunit.xml is no longer needed in order to run tests and we suggest to delete it. The test configuration is now done automatically if possible. In case the tests do no longer work check out the [tests] section in config/global.ini.php

Library updates

  • Code for manipulating IP addresses has been moved to a separate standalone component: piwik/network. Backward compatibility is kept in Piwik core.

Piwik 2.8.2

Library updates

  • Updated AngularJS from 1.2.25 to 1.2.26
  • Updated jQuery from 1.11.0 to 1.11.1

Piwik 2.8.0

Breaking Changes

  • The Auth interface has been modified, existing Auth implementations will have to be modified. Changes include:
    • The initSession method has been moved. Since this behavior must be executed for every Auth implementation, it has been put into a new class: SessionInitializer. If your Auth implementation implements its own session logic you will have to extend and override SessionInitializer.
    • The following methods have been added: setPassword, setPasswordHash, getTokenAuthSecret and getLogin.
    • Clarifying semantics of each method and what they must support and can support.
    • Read the documentation for the Auth interface to learn more.
  • The Piwik\Unzip\* classes have been extracted out of the Piwik repository into a separate component named Decompress.
    • Piwik\Unzip has not moved, it is kept for backward compatibility. If you have been using that class, you don't need to change anything.
    • The Piwik\Unzip\* classes (Tar, PclZip, Gzip, ZipArchive) have moved to the Piwik\Decompress\* namespace (inside the new repository).
    • Piwik\Unzip\UncompressInterface has been moved and renamed to Piwik\Decompress\DecompressInterface (inside the new repository).

Deprecations

  • The Piwik::setUserHasSuperUserAccess method is deprecated, instead use Access::doAsSuperUser. This method will ensure that super user access is properly rescinded after the callback finishes.
  • The class \IntegrationTestCase is deprecated and will be removed from February 6th 2015. Use \Piwik\Tests\Framework\TestCase\SystemTestCase instead.
  • The class \DatabaseTestCase is deprecated and will be removed from February 6th 2015. Use \Piwik\Tests\Framework\TestCase\IntegrationTestCase instead.
  • The class \BenchmarkTestCase is deprecated and will be removed from February 6th 2015. Use \Piwik\Tests\Framework\TestCase\BenchmarkTestCase instead.
  • The class \ConsoleCommandTestCase is deprecated and will be removed from February 6th 2015. Use \Piwik\Tests\Framework\TestCase\ConsoleCommandTestCase instead.
  • The class \FakeAccess is deprecated and will be removed from February 6th 2015. Use \Piwik\Tests\Framework\Mock\FakeAccess instead.
  • The class \Piwik\Tests\Fixture is deprecated and will be removed from February 6th 2015. Use \Piwik\Tests\Framework\Fixture instead.
  • The class \Piwik\Tests\OverrideLogin is deprecated and will be removed from February 6ths 2015. Use \Piwik\Framework\Framework\OverrideLogin instead.

New API Features

  • The pivotBy and related query parameters can be used to pivot reports by another dimension. Read more about the new query parameters here.

Library updates

  • Updated AngularJS from 1.2.13 to 1.2.25

New commands

  • generate:angular-directive lets you easily generate a template for a new angular directive for any plugin.

Internal change

  • Piwik 2.8.0 now requires PHP >= 5.3.3.
  • If you use an older PHP version, please upgrade now to the latest PHP so you can enjoy improvements and security fixes in Piwik.

Piwik 2.7.0

Reporting APIs

  • Several APIs will now expose a new metric nb_users which measures the number of unique users when a User ID is set.
  • New APIs have been added for Content Tracking feature: Contents.getContentNames, Contents.getContentPieces

Deprecations

  • The Piwik\Menu\MenuAbstract::add() method is deprecated in favor of addItem(). Read more about this here: #6140. We do not plan to remove the deprecated method before Piwik 3.0.

New APIs

New commands

  • core:clear-caches Lets you easily delete all caches. This command can be useful for instance after updating Piwik files manually.

Piwik 2.6.0

Deprecations

  • The 'json' API format is considered deprecated. We ask all new code to use the 'json2' format. Eventually when Piwik 3.0 is released the 'json' format will be replaced with 'json2'. Differences in the json2 format include:
    • A bug in JSON formatting was fixed so API methods that return simple associative arrays like array('name' => 'value', 'name2' => 'value2') will now appear correctly as {"name":"value","name2":"value2"} in JSON API output instead of [{"name":"value","name2":"value2"}]. API methods like SitesManager.getSiteFromId & UsersManager.getUser are affected.

Reporting API

  • If an API returns an indexed array, it is now possible to use filter_limit and filter_offset. This was before only possible if an API returned a DataTable.
  • The Live API now returns only visitor information of activated plugins. So if for instance the Referrers plugin is deactivated a visitor won't contain any referrers related properties. This is a bugfix as the API was crashing before if some core plugins were deactivated. Affected methods are for instance getLastVisitDetails or getVisitorProfile. If all core plugins are enabled as by default there will be no change at all except the order of the properties within one visitor.

New commands

  • core:run-scheduled-tasks lets you run all scheduled tasks due to run at this time. Useful for instance when testing tasks.

Internal change

  • We removed our own autoloader that was used to load Piwik files in favor of the composer autoloader which we already have been using for some libraries. This means the file core/Loader.php will no longer exist. In case you are using Piwik from Git make sure to run php composer.phar self-update && php composer.phar install to make your Piwik work again. Also make sure to no longer include core/Loader.php in case it is used in any custom script.
  • We do no longer store the list of plugins that are used during tracking in the config file. They are dynamically detect instead. The detection of a tracker plugin works the same as before. A plugin has to either listen to any Tracker.* or Request.initAuthenticationObject event or it has to define dimensions in order to be detected as a tracker plugin.

Piwik 2.5.0

Breaking Changes

  • Javascript Tracking API: if you are using getCustomVariable function to access custom variables values that were set on previous page views, you now must also call storeCustomVariablesInCookie before the first call to trackPageView. Read more about Javascript Tracking here.
  • The settings API will receive the actual entered value and will no longer convert characters like & to &amp;. If you still want this behavior - for instance to prevent XSS - you can define a filter by setting the transform property like this: $setting->transform = function ($value) { return Common::sanitizeInputValue($value); }
  • Config setting disable_merged_assets moved from Debug section to Development. The updater will automatically change the section for you.
  • API.getRowEvolution will throw an exception if a report is requested that does not have a dimension, for instance VisitsSummary.get. This is a fix as an invalid format was returned before see #5951
  • MultiSites.getAll returns from now on always an array of websites. In the past it returned a single object and it didn't contain all properties in case only one website was found which was a bug see #5987

Deprecations

The following events are considered as deprecated and the new structure should be used in the future. We have not scheduled when those events will be removed but probably in Piwik 3.0 which is not scheduled yet and won't be soon. New features will be added only to the new classes.

  • API.getReportMetadata, API.getSegmentDimensionMetadata, Goals.getReportsWithGoalMetrics, ViewDataTable.configure, ViewDataTable.getDefaultType: use Report class instead to define new reports. There is an updated guide as well Part1
  • WidgetsList.addWidgets: use Widgets class instead to define new widgets
  • Menu.Admin.addItems, Menu.Reporting.addItems, Menu.Top.addItems: use Menu class instead
  • TaskScheduler.getScheduledTasks: use Tasks class instead to define new tasks
  • Tracker.recordEcommerceGoal, Tracker.recordStandardGoals, Tracker.newConversionInformation: use Conversion Dimension class instead
  • Tracker.existingVisitInformation, Tracker.newVisitorInformation, Tracker.getVisitFieldsToPersist: use Visit Dimension class instead
  • ViewDataTable.addViewDataTable: This event is no longer needed. Visualizations are automatically discovered if they are placed within a Visualizations directory inside the plugin.

New features

Translation search

As a plugin developer you might want to reuse existing translation keys. You can now find all available translations and translation keys by opening the page "Settings => Development:Translation search" in your Piwik installation. Read more about internationalization here.

Reporting API

It is now possible to use the filter_sort_column parameter when requesting Live.getLastVisitDetails. For instance &filter_sort_column=visitCount.

@since annotation

We are using @since annotations in case we are introducing new API's to make it easy to see in which Piwik version a new method was added. This information is now displayed in the Classes API-Reference.

New APIs

  • Report to add a new report
  • Action Dimension to add a dimension that tracks action related information
  • Visit Dimension to add a dimension that tracks visit related information
