Release of PHP Extension v5.0.54

• Bugfix: Debian Package detection of PHP installation on official Docker PHP images didn’t work anymore because of new installation path of PHP.
• Bugfix: Crash when using new shell function instrumentation released in 5.0.46 with unsupported parameter types that were not a string
• Improvement: Debian Packaging now includes support for ZTS builds found in /etc/php/*-zts and extension directories ending in -zts.
• Feature: Add INI settings to enable/disable every individual extension or library instrumentation. See phpinfo for tideways.features.* settings.
