• A bug is fixed in loop unroller which might lead to wrong condition codes being generated in the unrolled loop.
• Fixed a bug that caused ServiceHub.Host.CLR.x64 to stop working.
• Fixes issue in Chinese version of compiler errors C4533 and C2362 which resulted in incorrect order of string substitution for those languages.
• Improved stability of the Diagnostic Tools and Performance Profiler.
• Code generation problem causing crash with pure virtual destructor in const object
• Fixed a constant evaluation regression from 16.5 Preview 2
• Fixed an issue where MacOS couldn't be paired.
• Fixed an issue where the Diagnostic Tools while debugging and Performance Profiler fail to launch on XBox devices. 

These are the customer-reported issues addressed in 15.8.2:

• Publish single file context menu item missing.
• Git network operations not working: Cannot spawn git-askpass.exe.
• "Visual C++ Resource Editor Package" load failed.
• Preview Transform gives error.
• Cannot type close brace.
• Object reference not set to an instance of an object when deploying Service Fabric project after update 15.8.0.
• "The given path's format is not supported" installation error.
• Task ExpandPriContent failed. Illegal characters in path.
• "Could not create instance of type System.Collections.Genertic.Iset'1[Signer]" installer error.
• Service fabric deployment fails in 15.8.0.
• Cannot create app package for Windows store.
• Incorrect code generation for strongly-typed resources.
• Keyboard binding for Italian layout.
• IntelliSense broken #9999.
• When working on a Unity project and Unity rewrites multiple project files, the Visual Studio Tools for Unity will now automatically reload the solution.
• The customer will now get a dialog to close Office applications if they are blocking the Visual Studio install and causing a failure of 1303. 

• Access violation C++ /CLI 15.9.5 ISO C++ Latest Draft Standard since 15.9.5.
• PGO Code Gen Bug - Vectorized instruction accessing memory OOB.
• We have implemented a C++ compiler fix to correct exception handling support for code using setjmp/longjmp in Release mode.
• We have implemented a C++ linker fix regarding information in PDB where the incorrect module info could result in heap corruption when producing a stripped PDB file either by PDBCopy.exe or by link.exe when option /PDBSTRIPPED is specified.
• We have corrected dual signing of the ARM64 Visual C++ Redistributable installer. 

NuGet 5.8 is included in Visual Studio 16.8 and .NET 5.0 out of the box. You can also download NuGet 5.8 for Windows, macOS, and Linux as a standalone executable. 

• VS is more responsive when running Git operations.
• Debugging large solutions with /debug:fastlink PDBs is more robust. Changes in the PDB/DIA lead to reduced latency and a 30% reduction in heap memory consumption in the VS debugger that used to cause crashes.
• C++ compiler bugfixes:
  • Fix for the SSA optimizer incorrectly sinking a function call past a store to a variable used in a __finally handler.
  • Fix for the SSA optimizer sometimes incorrectly analyzing memory loads from locations with negative offsets.
  • Fix for the optimizer incorrectly transforming a pre-incremented loop into a post-incremented loop. This was found compiling the ICU project.
• Microsoft bumped up the Java™ Development Kit 8 to Update 172 (JDK version 8u172).
