Note: WSL will install Ubuntu version 16.04 (Xenial) instead of Ubuntu 14.04 (Trusty) in an upcoming release.  This change will apply to Insiders installing new instances (lxrun.exe /install or first run of bash.exe).  Existing instances with Trusty will not be upgraded automatically. Users can upgrade their Trusty image to Xenial using the do-release-upgrade command.

Known Issue

WSL is experiencing an issue with some socket implementations. The bugcheck manifests itself as a crash with the error “ATTEMPTED EXECUTE OF NOEXECUTE MEMORY”. The most common manifestation of this issue is a crash when using ssh. The root cause is fixed on internal builds and will be pushed to Insiders at the earliest opportunity.

Fixed

• Implemented the chroot system call
• Improvements in inotify including support for notifications generated from Windows applications on DrvFs
• Socket binding to IPV6:: now supports IPV6_V6ONLY (GH #68, #157, #393, #460, #674, #740, #982, #996)
• WNOWAIT behavior for waitid systemcall implemented (GH #638)
• Support for IP socket options IP_HDRINCL and IP_TTL
• Zero-length read() should return immediately (GH #975)
• Correctly handle filenames and filename prefixes that don't include a NULL terminator in a .tar file.
• epoll support for /dev/null
• Fix /dev/alarm time source
• Bash -c now able to redirect to a file
• Additional bugfixes and improvements
