@ -3,6 +3,7 @@ Version 0.11.1 (unreleased)
|
||||
Bugfix:
|
||||
* Fix building of the range-v3 dependency. The conan remote URL for this dependency changed and we have to use the new URL. See https://github.com/cryfs/cryfs/issues/398
|
||||
* Update to CryptoPP 8.6. This fixes a rare bug where CryptoPP 8.5 encrypts data wrongly, see https://github.com/weidai11/cryptopp/issues/1069
|
||||
* cryfs-unmount correctly unmounts paths that contain spaces, see https://github.com/cryfs/cryfs/issues/372
