Cryptsetup 2.3.3 Release Notes
==============================
Stable bug-fix release.
All users of cryptsetup 2.x should upgrade to this version.
Changes since version 2.3.2
~~~~~~~~~~~~~~~~~~~~~~~~~~~
* Fix BitLocker compatible device access that uses native 4kB sectors.
Devices formatted with storage that natively support 4096-bytes
sectors can also use this sector size for encryption units.
* Support large IV count (--iv-large-sectors) cryptsetup option
for plain device mapping.
The large IV count is supported in dm-crypt together with larger
sector encryption. It counts the Initialization Vector (IV) in
a larger sector size instead of 512-bytes sectors.
This option does not have any performance or security impact,
but it can be used for accessing incompatible existing disk images
from other systems.
Only open action with plain device type and sector size > 512 bytes
are supported.
* Fix a memory leak in BitLocker compatible handling.
* Allow EBOIV (Initialization Vector algorithm) use.
The EBOIV initialization vector is intended to be used internally
with BitLocker devices (for CBC mode). It can now be used also
outside of the BitLocker compatible code.
* Require both keyslot cipher and key size options.
If these LUKS2 keyslot parameters were not specified together,
cryptsetup silently failed.
* Update to man pages and FAQ.
