+v1.5B1 (2019.3 B1)::
+
+Changes since v1.4:
+
+* Extended attribute support has been added for all WinFsp API's: native, .NET, FUSE2 and FUSE3.
+* Initial FastIO support has been added. FastIO operations are enabled on cache-enabled file systems with the notable exception of `FastIoQueryOpen`, which allows opening files in kernel mode; this operation requires the file system to specify the `FSP_FSCTL_VOLUME_PARAMS::AllowOpenInKernelMode` flag.
+* Fixes for very large (> 4GiB) files. (Thanks @dworkin.)
+* A fix for an invalid UID to SID mapping on domains with a lot of users. (Thanks @sganis.)
+* A fix on the C++ layer. (Thanks @colatkinson.)
+
+v1.4.19049 (2019.2)::
+
+Changes since v1.3:
+
+* FUSE3 API (version 3.2) is now available. The FUSE2 API (version 2.8) also remains supported.
+* New `Control` file system operation allows sending custom control codes to the file system using the Windows `DeviceIoControl` API. FUSE `ioctl` is also supported.
+* New `SetDelete` file system operation can optionally be used instead of `CanDelete`. `SetDelete` or `CanDelete` are used to handle the file "disposition" flag, which determines if a file is marked for deletion. See the relevant documentation for more details.
+* `FlushAndPurgeOnCleanup` has now been added to the .NET API. (GitHub PR #176; thanks @FrKaram.)
+* The Launcher now supports running file systems under the user account that started them. Use `RunAs="."` in the file system registry entry.
+* New sample file system "airfs" contributed by @JohnOberschelp. Airfs is an in-memory file system like Memfs on which it is based on; it has received substantial improvements in how the file name space is maintained and has been modified to use modern C++ techniques by John.
+* New sample file system "passthrough-fuse3" passes all operations to an underlying file system. This file system is built using the FUSE3 API. It builds and runs on both Windows and Cygwin.
+* The FUSE layer now supports multiple file systems within a single process. This is a long standing problem that has been fixed. (GitHub issue #135.)
+* The FSD includes a fix for a Windows problem: that case-sensitive file systems do not work properly when mounted as directories. See FAQ entry #3.
+* The FSD includes a fix for a rare but serious problem. (GitHub issue #177. Thanks @thinkport.)
+* The FSD includes a fix for an incompatibility with DrWeb Antivirus. (GitHub issue #192)
+* The DLL includes a fix for an errorenous `STATUS_ACCESS_DENIED` on read-only directories. (GitHub issue #190. Thanks @alfaunits.)
+* The FUSE layer includes a fix for the `ioctl` operation. (GitHub PR #214. Thanks @felfert.)
