- LogManager.Setup().SetupSerialization(s => s.RegisterObjectTransformation(...)) for overriding default property reflection (@snakefoot + @304NotModified + @Giorgi + @mmurrell)
- LogManager.Setup().SetupSerialization(s => s.RegisterConditionMethod(...)) can use lambda methods and not just static methods (@snakefoot)
- ${level:format=FullName} will expand Info + Warn to their full name (@snakefoot)
- FileTarget - Supports MaxArchiveDays for cleanup of old files based on their age (@snakefoot)
- Layout.FromMethod to create Layout directly from a lambda method (@snakefoot)
- Layout.FromString to create Layout directly from string along with optional parser validation (@snakefoot)

- FileTarget - Supports ArchiveOldFileOnStartupAboveSize for cleanup of existing file when above size (@Sam13)
- InternalLogger - Added LogMessageReceived event (@304NotModified)
- DatabaseTarget - Assign connection properties like SqlConnection.AccessToken (@304NotModified + @snakefoot)
- DatabaseTarget - Assign command properties like SqlCommand.CommandTimeout (@snakefoot)

## Improvements

- FileTarget - ConcurrentWrites=true on NetCore now much faster when archive enabled (@snakefoot)
- JsonConverter - Write DateTime directly without string allocation (@snakefoot)
- XmlLayout - Removed unnecessary double conversion to string (@snakefoot)
- WebServiceTarget - Reduced memory allocations by removing unnecessary delegate capture (@snakefoot)
- NetworkTarget - Reduced memory allocation for encoding into bytes without string allocation (@snakefoot)
- AsyncTaskTarget - Skip default AsyncWrapper since already having internal queue (@snakefoot)
- Mark Condition Expressions as ThreadSafe to improve concurrency in Layouts (@snakefoot)
- DatabaseTarget - Added IsolationLevel option that activates transactions for better batching performance (@snakefoot)
- SimpleLayout - Assignment of string-reference with null-value will translate into FixedText (@304NotModified)
- AsyncWrapper - Less aggressive with scheduling timer events for background writing (@snakefoot)
- Faster assignment of properties accessed through reflection (@304NotModified)
