Cryptsetup 2.3.1 Release Notes
==============================
Stable bug-fix release.

All users of cryptsetup 2.x should upgrade to this version.

Changes since version 2.3.0
~~~~~~~~~~~~~~~~~~~~~~~~~~~

* Support VeraCrypt 128 bytes passwords.
  VeraCrypt now allows passwords of maximal length 128 bytes
  (compared to legacy TrueCrypt where it was limited by 64 bytes).

* Strip extra newline from BitLocker recovery keys
  There might be a trailing newline added by the text editor when
  the recovery passphrase was passed using the --key-file option.

* Detect separate libiconv library.
  It should fix compilation issues on distributions with iconv
  implemented in a separate library.

* Various fixes and workarounds to build on old Linux distributions.

* Split lines with hexadecimal digest printing for large key-sizes.

* Do not wipe the device with no integrity profile.
  With --integrity none we performed useless full device wipe.

* Workaround for dm-integrity kernel table bug.
  Some kernels show an invalid dm-integrity mapping table
  if superblock contains the "recalculate" bit. This causes
  integritysetup to not recognize the dm-integrity device.
  Integritysetup now specifies kernel options such a way that
  even on unpatched kernels mapping table is correct.

* Print error message if LUKS1 keyslot cannot be processed.
  If the crypto backend is missing support for hash algorithms
  used in PBKDF2, the error message was not visible.

* Properly align LUKS2 keyslots area on conversion.
  If the LUKS1 payload offset (data offset) is not aligned
  to 4 KiB boundary, new LUKS2 keyslots area in now aligned properly.

* Validate LUKS2 earlier on conversion to not corrupt the device
  if binary keyslots areas metadata are not correct.
