Mono 3.8.0 has 711 commits since the last release. This is the work of 61 contributors since May 28. 58 bugs were fixed.
- Major performance and scalability improvements across the the whole runtime.
- Finished the Windows 64 port.
- Debugger wire protocol optimized for usb connections.
- Updated wire protocol better handles high latency connections such as those found when doing USB debugging.
- Client library now aggressively caches information and batches requests. Under one test scenario single stepping packets transmitted dropped from 2233 to only 16, with the latency going from seconds to 20 milliseconds.
- The JIT now better handles long remainders by powers of two, generating significantly better code.
- Over 10x faster code is generated for delegates that are only invoked once. C# features such as async and LINQ produce a lot of those delegates, so this improvement will impact everyone.
- Improved alias analysis can now handle second order aliases and eliminate null checks.
- The runtime now has a concurrently readable hashtable that can makes reflection heavy workloads significantly faster and more scalable.
- Optimized one of the core data structures of the garbage collector; should result in 5-10% reduction in collection times.
- Fix the leaking of mach ports introduced by 98bbf8512aec0fa01b4426583280f6d231d22187. Fixes #22068
- Fix Process.PrivateMemorySize64 etc. on ios. Fixes #21882

- Added new mono_domain_set_config function; used to fix ConfigurationErrorsException in #10468
- Only apply the maverick stack size hack to the main thread. Fixes #10096
- Don't hardcode the temp dir to /tmp, use g_get_tmp_dir instead. Fixes #20894
- Explicit thread GC data around instead of relying on TLS storage. Fixes #20360
- Make WaitForPendingFinalizers () really wait for the finalizers added by a previous GC. Fixes #20503
- Fix the marshal7.cs test, longs can be aligned to 4 bytes on 32 bit linux, and the runtime no longer aligns structure sizes to 8 bytes. Fixes #20788
- Fix the popping of LMF frames during unwinding. Fixes #20616
- Fix the marshalling of ByValTStr types which have a size specified. Fixes #20674
- Fix the decoding of MonoJitInfo. Fixes #16439
- Make it possible to create views to magic zero size files such as /dev/zero. Fixes #19460
- Free static bound delegate wrappers of dynamic methods. Fixes #19058
- Don't perform double accounting of offset for named memory segments. Fixes #20591
- Avoid joining attached threads. Fixes #19343
- Fix support for custom marshallers defined in other assemblies. Fixes #20020
- Fix a jit assertion on a class which contains an empty struct as a static field. Fixes #20349
- Applied patch from Kyle Edwards [email protected]. Fix isinf () check with clang. Fixes #20244
- Fix constrained type unwrap for enum types. Fixes #18371
- Handle quoted filename value. Fixes #21960
- Correctly handle partial chunk sizes. Fixes #20583
- Tweak Dictionary initial capacity to be more conservative. Fixes #21375
- Handle closed-over-null delegates created with IL when using InvokeDynamic. Fixes #21196
- Fix a race in a Task test. Fixes #20921
- Contract the values array when decoding an array with a negative number and a trailer that evals to zero. Fixes #20456
- Fixes issue with expression columns and IsNull. Fixes #20925
- Array qsort without head allocation. Fixes #20922
- Enum::TryParse ignores leading whitespaces. Fixes #20870
- Fix disposing of DelegatingHandler. Fixes #20818
- Fix digest authentication (bug #18799)
- Only recycle ServicePoints from the idle timer (fixes #19823)
- Changed ConcurrentDictionary.Contains(KeyValuePair<TKey, TValue>) to also compare value. Fixes #16990

- Effective base class can include inherited types. Fixes #21390
- Handle duplicate resume point registration. Fixes #21387
- Arguments can be empty when reporting missing params argument. Fixes #21215
- Flow analysis of moved arguments. Fixes #20983
- Run new initializer await checks only in async context. Fixes #20614
- [system.data] Parse numeric expressions using invariant culture. Fixes #20582
- Reachability analysis should ignore local variables declarations. Fixes #20603
- Check for missing dependencies of container types. Fixes #20382
- Resolve event expression when testing left side expression. Fixes #20493
- Flow analysis of binary expressions not using logical operators. Fixes #20515
- Add 4.5.1 framework. Fixes #20827
- Parsing conditions with property references. Fixes #20634
- Implements property functions using constructor syntax. Fixes #12999
- Avoid clearning event requests if they reference an assembly which is unloaded. Instead, remove the assembly reference from the event request so it stays active. Fixes #9924.
