v2.0.0-rc2: Merge pull request #214 from mbdavid/szurgot

New features in RC2

• Portable version: NuGet package: Lite.Core that support PCL/UWP

• Transactions are back
• No more ThreadSafe (only ProcessSafe). Always create LiteDatabase instances.
• Close datafile after each command execution
• BsonMapper.Global are back
• RegisterAutoId<T> are back

Changes in RC2

• To implement new disk read/write access, new datafile version was required.
• Removed OnModelCreating. Use BsonMapper.Global instance
• Removed UserVersion update checking. Now UserVersion is only an int stored in header page (update version must be developed in your solution)

v2.0.0-rc

New features in RC

• Datafile encryption: now you can use password to protect your datafile (uses DES cryptography)
• Database upgrade from v.0.9.0 and 1.0.x (use LiteDB.Shell.exe myold.db --upgrade mynew.db)
• Export database as dump file (insert commands)
• Added collections stats (data/index pages, disk usage, ...) shell: db.collection.stats

Changes in RC

• Remove virtual fields
• Better concurrency support
• Better memory manager: using disk cache/journal in big transactions. Now LiteDB avoid too many memory consume when are reading/writing too long data loop in a collection.

Roadmap to v2
