-Cryptsetup 1.6.4 Release Notes
-==============================
-
-Changes since version 1.6.3
-
-* Implement new erase (with alias luksErase) command.
-
- The erase cryptsetup command can be used to permanently erase
- all keyslots and make the LUKS container inaccessible.
- (The only way to unlock such device is to use LUKS header backup
- created before erase command was used.)
-
- You do not need to provide any password for this operation.
-
- This operation is irreversible.
-
-* Add internal "whirlpool_gcryptbug hash" for accessing flawed
- Whirlpool hash in gcrypt (requires gcrypt 1.6.1 or above).
-
- The gcrypt version of Whirlpool hash algorithm was flawed in some
- situations.
-
- This means that if you used Whirlpool in LUKS header and upgraded
- to new gcrypt library your LUKS container become inaccessible.
-
- Please refer to cryptsetup FAQ for detail how to fix this situation.
-
-* Allow to use --disable-gcrypt-pbkdf2 during configuration
- to force use internal PBKDF2 code.
-
-* Require gcrypt 1.6.1 for imported implementation of PBKDF2
- (PBKDF2 in gcrypt 1.6.0 is too slow).
-
-* Add --keep-key to cryptsetup-reencrypt.
-
- This allows change of LUKS header hash (and iteration count) without
- the need to reencrypt the whole data area.
- (Reencryption of LUKS header only without master key change.)
-
-* By default verify new passphrase in luksChangeKey and luksAddKey
- commands (if input is from terminal).
-
-* Fix memory leak in Nettle crypto backend.
-
-* Support --tries option even for TCRYPT devices in cryptsetup.
-
-* Support --allow-discards option even for TCRYPT devices.
- (Note that this could destroy hidden volume and it is not suggested
- by original TrueCrypt security model.)
-
-* Link against -lrt for clock_gettime to fix undefined reference
- to clock_gettime error (introduced in 1.6.2).
-
-* Fix misleading error message when some algorithms are not available.
-
-* Count system time in PBKDF2 benchmark if kernel returns no self usage info.
- (Workaround to broken getrusage() syscall with some hypervisors.)
