Changelog for APM
Release What has changed?
2.0.2 Fixed:
- Compilation issue on non ZTS setup
2.0.1 Fixed:
- #10: Bad configure message (thx @RemiCollet)
- #11: Bad version reported (thx @RemiCollet)
- #13: ZTS build is broken (thx @RemiCollet)
- APM not working with XDebug
If Xdebug is enabled as in xdebug_enable() or xdebug.default_enable, APM error callback will not be called.
Use xdebug.default_enable=0 or xdebug_disable() to go through APM error handling.

Improved:
- #12: Installation of files via pecl install
- StatsD driver (thanks @0livier for the discovery!)

Changed:
- Web frontend located on its own repository: https://github.com/patrickallaert/php-apm-web
2.0.0 New drivers:
- StatsD
- Socket

Added:
- Per-driver option 'apm._store_silenced_events that lets you toggle whether to store silenced (@-ed) errors (thanks Mathieu Kooiman (@mathieuk))
- apm.*_exception_mode configuration to control exception collection
- Auto creation of SQLite and MariaDB/MySQL schemas
- Stats:
- User and System CPU time
- Memory Peak Usage
