## Bugfixes
- LogFactory - Fix deadlock issue with AutoReload (@snakefoot)
- JsonLayout - Fixed ThreadAgnostic to correctly capture context when using nested JsonLayout (@snakefoot)
- ExceptionLayoutRenderer - Fixed so Format option HResult also works for NetCore (@snakefoot)
- Log4JXml Layout - Render NDLC + NDC scopes in correct order (@adanek + @304NotModified)
- Logger - Added exception handler for CallSite capture for platform that fails to capture StackTrace (@snakefoot)
- StringSplitter - Fixed quote handling when reading elements for config list-properties (@snakefoot)
- Utilities: fix ConversionHelpers.TryParseEnum for white space (@304NotModified)

## Features
- LogManager.Setup() allows fluent configuration of LogFactory options (@snakefoot + @304NotModified)
- 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)
- ${dir-separator} for rendering platform specific directory path separator (@304NotModified)
- 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)
- ${onHasProperties} for only rendering when logevent includes properties from structured logging (@snakefoot)

## Improvements
- XmlLoggingConfiguration - Marked legacy constructors with ignoreErrors parameter as obsolete (@snakefoot)
- LoggingConfiguration - Perform checking of unused targets during initialization for better validation (@snakefoot)
- EventLogTarget - Improve diagnostics logging when using dynamic EventLog source (@snakefoot)
- ${longdate} now also supports raw value for use as DatabaseTarget parameter with DbType (@snakefoot)
- SourceLink for GitHub for easy debugging into the NLog source code (@304NotModified)
- JsonLayout - EscapeForwardSlash now automatically applies to sub-attributes (@snakefoot)
- TraceTarget - Introduced EnableTraceFail=false to avoid Environment.FailFast (@snakefoot)
- ExceptionLayoutRenderer - Improved error message when Format-token parsing fails (@snakefoot)
- AutoFlushWrapper - Set AutoFlush=false for AsyncTaskTarget by default (@snakefoot)
- LocalIpAddressLayoutRenderer - Higher priority to network-addresses that has valid gateway adddress (@snakefoot)
- LogFactory - Flush reports to InternalLogger what targets produces timeouts (@snakefoot)  

## Performance
- ObjectGraphScanner - Avoid holding list.SyncRoot lock while scanning (@snakefoot)
- 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)
- ${replace} - Faster search and replace when not explicitly have requested regex support (@snakefoot)
- Skip need for Activator.CreateInstance in DbTypeSetter (@304NotModified)
