# List of important changes in NLog 4.5

## Features:

- Support for .Net Standard 1.5 #2341
- Support for .Net Standard 2.0 #2263 + #2402
- Support for UPW #2441
- Introduced Structured logging #2208 + #2262 + #2244
- Default file archive logic is now easier to use #1993
- Introduced InstallationContext.ThrowExceptions #2214
- WebServiceTarget can now batch multiple logevents into single request #2223
- WebServiceTarget - Allow configuration of proxy address #2375
- Json conversion also supports object properties #2179
- event-properties layout-renderer can now render objects as json #2241
- exception layout-renderer can now render exceptions as json #2357
- ${guid}, added GeneratedFromLogEvent #2226
- TraceTarget RawWrite to always perform Trace.WriteLine independent of LogLevel #1968
- Adding OverflowAction options to BufferingTargetWrapper #2276
- WhenRepeatedFilter #2123 + #2297
- ${callsite} added CleanNamesOfAsyncContinuations option #2292

- Added "regex-matches" for filtering #2437

## BugFixes:

- Improve archive stability during concurrent file access #1889
- FallbackGroup could lose log events #2265
- Exception separator should only be inserted for available items #2250
- ${exception} - only include separator when items are available #2257
- LogFactory - Fixes broken EventArgs for ConfigurationChanged #1897
- Do not report wrapped targets as unused targets #2290
- Added IIncludeContext, implemented missing properties #2117
- Improve logging of callsite linenumber for async-methods #2386
- NLogTraceListener - DisableFlush is enabled by default when AutoFlush=true #2407
- NLogViewer - Better defaults for connection limits #2404
- LoggingConfiguration.LoggingRules is not thread safe #2393, 2418

## Performance:

- More targets has OptimizeBufferReuse enabled by default #1913 + #1923 + #1912 + #1911 + #1910 + #1909 + #1908 + #1907
- StringBuilderPool - Improved Layout Render Performance by reusing StringBuilders #2208
- JsonLayout - Improved Layout Performance, by optimizing use of StringBuilder #2208
- FileTarget - Faster byte-encoding of log messsages, by using crude Encoding.GetMaxByteCount() instead of exact Encoding.GetByteCount() #2208
- Target - Precalculate Layout should ignore sub-layouts for complex layout (Ex Json) #2378
