• Fix CodeQL Password in configuration file Rule False Positives (by @justinmichaels)

2.0.15

Attention: .NET 3.5 Client Profile is no longer supported. I'm really sorry, I've tried to keep as many of the legacy targets available as possible, but after spending another 4 or so hours trying to get net35-client to build on any machine, I've given up - as far as I'm aware, this should only affect Windows XP clients. I'm afraid 2.0.14 was the end of the road for you. Apache log4net 2.0.15 addresses reported issues:

Bug fixes

• Improper usage of xml namespacing for netfx targets after a netstandard update ( LOG4NET-685, related LOG4NET-683)
• Locking hashtables during write in RenderMap calls to make them thread-safe ( LOG4NET-646)
• An issue where RollingFilAppender would sometimes overwrite files instead of rolling them ( LOG4NET-672)

Enhancements

• Enforce TLS1.2 in the ps1 scripts provided for dev use
• Corrected links in README
• Open up the internals of LogEvent a bit for extension purposes
• Add information about FixFlags and performance to the BufferingAppender (and derivative) documentation

2.0.14

• Pull request by @NicholasNoise to address issues with logging via ado appender to PostgreSQL
• Community request to correctly handle null data in ReadOnlyPropertiesDictionary
• Pull request by @erikmav to use the numeric thread id for .net worker pool threads (LOG4NET-680)
• Pull request by @erikmav to dispose of WindowsIdentity retrieved in TryGetCurrentUserName() (LOG4NET-671)

2.0.13

Some minor updates:

• address deadlock with rolling file appender (https://issues.apache.org/jira/browse/LOG4NET-583)
• performance improvement for platforms not supporting WindowsIdentity (https://issues.apache.org/jira/browse/LOG4NET-652)
• allow using the netstandard2.0 libraries from within asp.net on net472 (#76)
• update to the log4j-alike output (#18)

This is essentially the same release as rc-1, with the artifacts updated so that unzipping them won't scatter files in the target.

2.0.12

• Fixes LOG4NET-(652|653)
• Should resolve issues with PlatformNotSupported exceptions raised on !win32 when attempting to include the current user name in logs.
