Cryptsetup 2.3.2 Release Notes
==============================
Stable bug-fix release.
All users of cryptsetup 2.x should upgrade to this version.
Changes since version 2.3.1
~~~~~~~~~~~~~~~~~~~~~~~~~~~
* Support compilation with json-c library version 0.14.
* Update FAQ document for some LUKS2 specific information.
* Add option to dump content of LUKS2 unbound keyslot:
cryptsetup luksDump --unbound -S <slot> <device>
or optionally with --master-key-file option.
The slot number --key-slot (-S) option is mandatory here.
An unbound keyslot store a key is that is not assigned to data
area on disk (LUKS2 allows to store arbitrary keys).
* Rephrase some error messages and remove redundant end-of-lines.
* Add support for discards (TRIM) for standalone dm-integrity devices.
Linux kernel 5.7 adds support for optional discard/TRIM operation
over dm-integrity devices.
It is now supported through --allow-discards integritysetup option.
Note you need to add this flag in all activation calls.
Note that this option cannot be used for LUKS2 authenticated encryption
(that uses dm-integrity for storing additional per-sector metadata).
* Fix cryptsetup-reencrypt to work on devices that do not allow
direct-io device access.
* Fix a crash in the BitLocker-compatible code error path.
* Fix Veracrypt compatible support for longer (>64 bytes) passphrases.
It allows some older images to be correctly opened again.
The issue was introduced in version 2.3.1.
