Changelog
---------
+v1.7-beta1, 2019-01-03
+* **Fix possible symlink race attacks in forward mode** when using allow_other + plaintextnames
+ * If you use *both* `-allow_other` *and* `-plaintextnames`, you should upgrade.
+ Malicous users could trick gocryptfs into modifying files outside of `CIPHERDIR`,
+ or reading files inside `CIPHERDIR` that they should not have access to.
+ * If you do not use `-plaintextnames` (disabled per default), these attacks do
+ not work as symlinks are encrypted.
+ * Forward mode has been reworked to use the "*at" family of system calls everywhere
+ (`Openat/Unlinkat/Symlinkat/...`).
+ * As a result, gocryptfs may run slightly slower, as the caching logic has been
+ replaced and is very simple at the moment.
+ * The possibility for such attacks was found during an internal code review.
v1.6.1, 2018-12-12
* Fix "Operation not supported" chmod errors on Go 1.11
