libcryfs/ChangeLog.txt

Version 0.9.0 (unreleased)
---------------
  (warning) file systems created with earlier CryFS versions are incompatible with this release
* Fully support file access times
* (for developers) New repository layout. All subrepositories have been merged to one directory
* (for developers) Using CMake instead of biicode as build system

Version 0.8.6
---------------
* Fix a deadlock that was caused when a very high load of parallel resize operations was issued, see https://github.com/cryfs/cryfs/issues/3
* Fix a bug that prevented deleting symlinks, see https://github.com/cryfs/cryfs/issues/2
* Gracefully accept modifications to the file access times instead of failing, although they're not stored yet (they will be stored in 0.9.0). This should fix https://github.com/cryfs/cryfs/issues/4

Version 0.8.5
---------------
* Fix package manager warning when installing the .deb package
* Offer a default configuration when creating new filesystems
* If the given base or mount directory doesn't exist, offer to create them

Version 0.8.4
---------------
* Offering .deb packages for Debian and Ubuntu
* Compatibility with 32bit systems
* Support files larger than 4GB

Version 0.8.3
---------------
* Ask for password confirmation when creating new filesystem
* Check for new CryFS versions and ask the user to update if a new version is available
* Implemented a mechanism that can show warnings about security bugs to users of a certain CryFS version. Let's hope this won't be necessary ;)
* Compatibility with GCC 4.8 (that allows compiling on Ubuntu 14.04 for example)

Version 0.8.2
---------------
* Mount directory, base directory, logfile and config file can be specified as relative paths
* Improved error messages

Version 0.8.1
---------------
* Config File Encryption: Configuration files are encrypted with two ciphers. The user specifies a password, which is then used with the scrypt KDF to generate the two encryption keys.
  - Inner level: Encrypts the config data using the user specified cipher.
  - Outer level: Encrypts the name of the inner cipher and the inner level ciphertext using aes-256-gcm.
  The config file is padded to hide the size of the configuration data (including the name of the cipher used).
* No external config file needed: If the configuration file is not specified as command line parameter, it will be put into the base directory. This way, the filesystem can be mounted with the password only, without specifying a config file on command line.
* Logfiles: Added a --logfile option to specify where logs should be written to. If the option is not specified, CryFs logs to syslog.
* Running in Background: Fixed daemonization. When CryFs is run without "-f" flag, it will run in background.
* Better error messages when base directory is not existing, not readable or not writeable.
* Allow --cipher=xxx to specify cipher on command line. If cryfs is creating a new filesystem, it will use this cipher. If it is opening an existing filesystem, it will check whether this is the cipher used by it.
* --show-ciphers shows a list of all supported ciphers
* --extpass allows using an external program for password input
* --unmount-idle x automatically unmounts the filesystem after x minutes without a filesystem operation.
