Microsoft has released the newest preview update (version 2.0.0) for Windows Subsystem for Linux (WSL). The new update brings multiple improvements with several experimental features like autoMemoryReclaim and Sparse VHD to help with cache memory and disk space management.

Microsoft explains:

We reclaim a fixed fraction of your VM’s memory size, which is calculated so that if your VM was full of reserved memory, it would go to zero reserved memory after 30 minutes (eg: if you have 3000MB of memory, we reclaim 100MB every minute ).

Also, there are network related improvements as well with Mirrored mode which adds IPv6 support, better VPN support, among others. Besides mirroring mode, DNS tunneling improvements and firewall support have also been added.

The release notes are given below:
