Release FreeSWITCH v1.10.3 Release · signalwire/freeswitch

This is a major bugfix release. As part of our continuing dedication to code quality we have resolved static analysis bugs in all of FreeSWITCH core and in most modules. And not just that. We got huge improvements in change inspections by focusing on the testing framework - our code quality tooling that already helping us fixing leaks, codecs, database logic issues, behavior instabilities and making dependency updates easier. Almost three hundred changes covering the entire codebase contain fixes for memory errors, potential crashes and misbehaviours.
