The main issue of the this release is Syslog compatibility.
New features
Backend (PHP)
When syslog is enabled the max log length is only 32k and formatting/replacing uses + as newline separator etc.
Error/back tracer's default stack frame limit is now configurable in the settings page.
Tracer now reduces stack frame limit automatically when exceeding max output length.
Logging/filing an error message and/or exception message via trace functions/methods is always allowed, if severity is more severe than WATCHDOG_DEBUG.
Obsoletes
Backend (PHP)
Removed settings option 'Prohibit the primary admin user from getting inspections of variables and traces'.
Removed settings option 'PHP inspections shan\'t default to display file and line of inspection function/method call'.
Inspect::log_db() is now deprecated, use inspect_log_message()/Inspect::logMessage() instead.
Inspect::log_file() is now deprecated, use inspect_file_message()/Inspect::fileMessage() instead.
Removed obsolete and deprecated classes InspectBs, InspectVar, InspectTrc and methods Inspect::_initSessionNo and functions inspect_log_get, inspect_trace_log_get.
