+v1.2 (2019-05-05):
+* Dramatic speed increase when opening many small files, such as with a Git repository
+* Fixed crash on surprise removals of removable devices

+* No longer creates free-space cache for very small chunks, so as not to confuse the Linux driver
+* Fixed corruption when very large file created and then immediately deleted
+* Minor bug fixes
+
 v1.1 (2018-12-15):
