Hello everybody,

I've released version 1.10 of WinBtrfs, the btrfs kernel driver for
Windows - this is the first release in more than two years.
https://github.com/maharmstone/btrfs

In this version:

* Added support for writing free-space bitmaps (reading was already
supported)
* Added support for writing compressed inline files (reading was already
supported)
* Improved handling of removable devices
* Tightened up error recovery on OOMs and ENOSPCs
* Fixed crash when moving files across subvolumes, such as to the
Recycle Bin
* Fixed crash when many files created simultaneously, e.g. by Steam
* Fixed extent tree corruption when writing to snapshots
* Fixed preallocation issues (fixes rclone)
* Fixed deadlock when querying hard links
* Fixed memory corruption relating to watching the Registry
* Fixed disk usage statistics for multi-device volumes
* Fixed FSCTL_DUPLICATE_EXTENTS_TO_FILE sent from 32-bit userspace
* Refactored to use same struct and constant definitions as on Linux

Thanks

Mark
