+  ```
+    [interop]
+
+    enabled=false # enable launch of Windows binaries; default is true
+
+    appendWindowsPath=false # append Windows path to $PATH variable; default is true
+  ```
+* Fix for getsockname not always returning UNIX socket family type [GH 1774]
+* Add support for TIOCSTI [GH 1863]
+* Non-blocking sockets in the process of connecting should return EAGAIN for write attempts [GH 2846]
+* Support interop on mounted VHDs [GH 3246, 3291]
+* Fix permission checking issue on root folder [GH 3304]
+* Limited support for TTY keyboard ioctls KDGKBTYPE, KDGKBMODE and KDSKBMODE.

+* Fix WSL launch issues when fast startup is enabled [GH 2576]
+* Unix sockets need to retain disconnected peer credentials [GH 3183]
+* Non-blocking Unix sockets failing indefinitely with EAGAIN [GH 3191]

+    * See [blog](https://blogs.msdn.microsoft.com/commandline/2018/06/14/improved-per-directory-case-sensitivity-support-in-wsl/) for more information.
+* Add wslconfig /terminate to stop running distributions.
+* Fix issue with the WSL shell context menu entries that do not correctly handle paths with spaces.
+* Expose per-directory case sensitivity as an extended attribute
+* ARM64: Emulate cache maintenance operations. Resolve [dotnet issue](https://github.com/dotnet/core/issues/1561).
+* DrvFs: only unescape characters in the private range that correspond to an escaped character.
+* Fix off-by-one error in ELF parser interpreter length validation [GH 3154]
+* WSL absolute timers with a time in the past do not fire [GH 3091]
+* Ensure newly created reparse points are listed as such in the parent directory.
+* Atomically create case sensitive directories in DrvFs.
+* Fixed an additional issue where multithreaded operations could return ENOENT even though the file exists. [GH 2712]
+* Fixed WSL launch failure when UMCI is enabled. [GH 3020]
+* Add explorer context menu to launch WSL [GH 437, 603, 1836]. To use, hold shift and right-click when in an explorer window.

+    * Note: dmesg is currently supported through the `/dev/kmsg` device interface. `syslog` syscall interface is not yet supported. And, so, some of the `dmesg` command line options such as `-S`, `-C` don't work.
+* Fixed an issue where multithreaded operations could return ENOENT even though the file exists. [GH 2712]
+* Change default gid and mode of serial devices to match native [GH 3042]
+* DrvFs now supports extended attributes.
+    * Note: DrvFs has some limitations on the name of extended attributes. Some characters (like '/', ':' and '\*') are not allowed, and extended attribute names are not case sensitive on DrvFs
