+Cryptsetup 1.1.0 Release Notes
+==============================
+
+Changes since version 1.0.7
+----------------------------
+
+Important changes:
+~~~~~~~~~~~~~~~~~~
+
+ * IMPORTANT: the default compiled-in cipher parameters changed
+ plain mode: aes-cbc-essiv:sha256 (default is backward incompatible!).
+ LUKS mode: aes-cbc-essiv:sha256 (only key size increased)
+ In both modes is now default key size 256bits.
+
+ * Default compiled-in parameters are now configurable through configure options:
+ --with-plain-* / --with-luks1-* (see configure --help)
+
+ * If you need backward compatible defaults for distribution use
+ configure --with-plain-mode=cbc-plain --with-luks1-keybits=128
+
+ Default compiled-in modes are printed in "cryptsetup --help" output.
+
+ * Change in iterations count (LUKS):
+ The slot and key digest iteration minimum count is now 1000.
+ The key digest iteration count is calculated from iteration time (approx 1/8 of req. time).
+ For more info about above items see discussion here: http://tinyurl.com/yaug97y
+
+ * New libcryptsetup API (documented in libcryptsetup.h).
+
+ The old API (using crypt_options struct) is still available but will remain
+ frozen and not used for new functions.
+ Soname of library changed to libcryptsetup.so.1.0.0.
+ (But only recompilation should be needed for old programs.)
+
+ The new API provides much more flexible operation over LUKS device for
+ applications, it is preferred that new applications will use libcryptsetup
+ and not wrapper around cryptsetup binary.
+
+ * New luksHeaderBackup and luksHeaderRestore commands.
+
+ These commands allows binary backup of LUKS header.
+ Please read man page about possible security issues with backup files.
+
+ * New luksSuspend (freeze device and wipe key) and luksResume (with provided passphrase).
+
+ luksSuspend wipe encryption key in kernel memory and set device to suspend
+ (blocking all IO) state. This option can be used for situations when you need
+ temporary wipe encryption key (like suspend to RAM etc.)
+ Please read man page for more information.
+
+ * New --master-key-file option for luksFormat and luksAddKey.
+
+ User can now specify pre-generated master key in file, which allows regenerating
+ LUKS header or add key with only master key knowledge.
+
+ * Uses libgcrypt and enables all gcrypt hash algorithms for LUKS through -h luksFormat option.
+
+ Please note that using different hash for LUKS header make device incompatible with
+ old cryptsetup releases.
+
+ * Introduces --debug parameter.
+
+ Use when reporting bugs (just run cryptsetup with --debug and attach output
+ to issue report.) Sensitive data are never printed to this log.
+
+ * Moves command successful messages to verbose level.
+
+ * Requires device-mapper library and libgcrypt to build.
+
+ * Uses dm-uuid for all crypt devices, contains device type and name now.
+
+ * Removes support for dangerous non-exclusive option
+ (it is ignored now, LUKS device must be always opened exclusive)
+
+Other changes:
+~~~~~~~~~~~~~~
+ * Fixed localization to work again. Also cryptsetup is now translated by translationproject.org.
+ * Fix some libcryptsetup problems, including
+ * exported symbols and versions in libcryptsetup (properly use versioned symbols)
+ * Add crypt_log library function.
+ * Add CRYPT_ prefix to enum defined in libcryptsetup.h.
+ * Move duplicate Command failed message to verbose level (error is printed always).
+ * Fix several problems in build system
+ * use autopoint and clean gettext processing.
+ * Check in configure if selinux libraries are required in static version.
+ * Fix build for non-standard location of gcrypt library.
+ * Add temporary debug code to find processes locking internal device.
+ * Fix error handling during reading passphrase.
+ * Fail passphrase read if piped input no longer exists.
+ * Fix man page to not require --size which expands to device size by default.
+ * Clean up Makefiles and configure script.
+ * Try to read first sector from device to properly check that device is ready.
+ * Move memory locking and dm initialization to command layer.
+ * Increase priority of process if memory is locked.
+ * Add log macros and make logging more consistent.
+ * Keyfile now must be provided by path, only stdin file descriptor is used (api only).
+ * Do not call isatty() on closed keyfile descriptor.
+ * Move key slot manipulation function into LUKS specific code.
+ * Replace global options struct with separate parameters in helper functions.
+ * Implement old API calls using new functions.
+ * Allow using passphrase provided in options struct for LuksOpen.
+ * Allow restrict keys size in LuksOpen.
+ * Fix errors when compiled with LUKS_DEBUG.
+ * Print error when getline fails.
+ * Completely remove internal SHA1 implementation code, not needed anymore.
+ * Pad luks header to 512 sector size.
+ * Rework read/write blockwise to not split operation to many pieces.
+ * Use posix_memalign if available.
+ * Fix segfault if provided slot in luksKillslot is invalid.
+ * Remove unneeded timeout when remove of temporary device succeeded.

+Cryptsetup 1.1.1 Release Notes
+==============================
+
+Changes since version 1.1.1-rc2
+* Fix luksClose error if underlying device is LVM logical volume.
+
+Changes since version 1.1.1-rc1
+* Fix automatic dm-crypt module loading.
+
+Changes since version 1.1.0
+
+Important changes:
+~~~~~~~~~~~~~~~~~~
+
+* Detects and use device-mapper udev support if available.
+
+ This should allow synchronisation with udev rules and avoid races with udev.
+
+ If package maintainer want to use old, direct libdevmapper device node creation,
+ use configure option --disable-udev.
+
+* Supports device topology detection for data alignment.
+
+ If kernel provides device topology ioctl calls, the LUKS data area
+ alignment is automatically set to optimal value.
+
+ This means that stacked devices (like LUKS over MD/LVM)
+ should use the most optimal data alignment.
+
+ (You can still overwrite this calculation using --align-payload option.)
+
+* Prefers some device paths in status display.
+ (So status command will try to find top level device name, like /dev/sdb.)
+
+* Fix package config file to use proper package version.
+
+Other changes:
+~~~~~~~~~~~~~~
+* Fix luksOpen reading of passphrase on stdin (if "-" keyfile specified).
+* Fix isLuks to initialise crypto backend (blkid instead is suggested anyway).
+* Properly initialise crypto backend in header backup/restore commands.
+* Do not verify unlocking passphrase in luksAddKey command.
+* Allow no hash specification in plain device constructor - user can provide volume key directly.
+* Try to use pkgconfig for device mapper library in configuration script.
+* Add some compatibility checks and disable LUKS suspend/resume if not supported.
+* Rearrange tests, "make check" now run all available test for package.
+* Avoid class C++ keyword in library header.

+== Cryptsetup 1.1.2 Release Notes ==
+
+This release fixes a regression (introduced in 1.1.1 version) in handling
+key files containing new line characters (affects only files read from
+standard input).
+
+Cryptsetup can accept passphrase on stdin (standard input).
+
+Handling of new line (\n) character is defined by input specification:
+
+ * if keyfile is specified as "-" (using --key-file=- of by "-" positional argument
+ in luksFormat and luksAddKey, like cat file | cryptsetup --key-file=- <action>),
+ input is processed as normal binary file and no new line is interpreted.
+
+ * if there is no key file specification (with default input from stdin pipe
+ like echo passphrase | cryptsetup <action>) input is processed as input from terminal,
+ reading will stop after new line is detected.
+
+Moreover, luksFormat now understands --key-file (in addition to positional key
+file argument).
+
+N.B. Using of standard input and pipes for passphrases should be avoided if possible,
+cryptsetup have no control of used pipe buffers between commands in scripts and cannot
+guarantee that all passphrase/key-file buffers are properly wiped after use.
+
+=== changes since version 1.1.1 ===
+
+ * Fix luksFormat/luksOpen reading passphrase from stdin and "-" keyfile.
+ * Support --key-file/-d option for luksFormat.
+ * Fix description of --key-file and add --verbose and --debug options to man page.
+ * Add verbose log level and move unlocking message there.
+ * Remove device even if underlying device disappeared (remove, luksClose).
+ * Fix (deprecated) reload device command to accept new device argument.
--- /dev/null
+== Cryptsetup 1.1.3 Release Notes ==
+
+=== changes since version 1.1.2 ===
+
+* Fix device alignment ioctl calls parameters.
+ (Device alignment code was not working properly on some architectures like ppc64.)
+
+* Fix activate_by_* API calls to handle NULL device name as documented.
+ (To enable check of passphrase/keyfile using libcryptsetup without activating the device.)
+
+* Fix udev support for old libdevmapper with not compatible definition.
+
+* Added Polish translation file.
--- /dev/null
+Cryptsetup 1.2.0 Release Notes
+==============================
+
+Changes since version 1.2.0-rc1
+
+ * Fix crypt_activate_by_keyfile() to work with PLAIN devices.
+ * Fix plain create command to properly handle keyfile size.
+ * Update translations.
+
+Changes since version 1.1.3
+
+Important changes
+~~~~~~~~~~~~~~~~~
+
+ * Add text version of *FAQ* (Frequently Asked Questions) to distribution.
+
+ * Add selection of random/urandom number generator for luksFormat
+ (option --use-random and --use-urandom).
+
+ (This affects only long term volume key in *luksFormat*,
+ not RNG used for salt and AF splitter).
+
+ You can also set the default to /dev/random during compilation with
+ --enable-dev-random. Compiled-in default is printed in --help output.
+
+ Be very careful before changing default to blocking /dev/random use here.
+
+ * Fix *luksRemoveKey* to not ask for remaining keyslot passphrase,
+ only for removed one.
+
+ * No longer support *luksDelKey* (replaced with luksKillSlot).
+ * if you want to remove particular passphrase, use *luksKeyRemove*
+ * if you want to remove particular keyslot, use *luksKillSlot*
+
+ Note that in batch mode *luksKillSlot* allows removing of any keyslot
+ without question, in normal mode requires passphrase or keyfile from
+ other keyslot.
+
+ * *Default alignment* for device (if not overridden by topology info)
+ is now (multiple of) *1MiB*.
+ This reflects trends in storage technologies and aligns to the same
+ defaults for partitions and volume management.
+
+ * Allow explicit UUID setting in *luksFormat* and allow change it later
+ in *luksUUID* (--uuid parameter).
+
+ * All commands using key file now allows limited read from keyfile using
+ --keyfile-size and --new-keyfile-size parameters (in bytes).
+
+ This change also disallows overloading of --key-size parameter which
+ is now exclusively used for key size specification (in bits.)
+
+ * *luksFormat* using pre-generated master key now properly allows
+ using key file (only passphrase was allowed prior to this update).
+
+ * Add --dump-master-key option for *luksDump* to perform volume (master)
+ key dump. Note that printed information allows accessing device without
+ passphrase so it must be stored encrypted.
+
+ This operation is useful for simple Key Escrow function (volume key and
+ encryption parameters printed on paper on safe place).
+
+ This operation requires passphrase or key file.
+
+ * The reload command is no longer supported.
+ (Use dmsetup reload instead if needed. There is no real use for this
+ function except explicit data corruption:-)
+
+ * Cryptsetup now properly checks if underlying device is in use and
+ disallows *luksFormat*, *luksOpen* and *create* commands on open
+ (e.g. already mapped or mounted) device.
+
+ * Option --non-exclusive (already deprecated) is removed.
+
+Libcryptsetup API additions:
+
+ * new functions
+ * crypt_get_type() - explicit query to crypt device context type
+ * crypt_resize() - new resize command using context
+ * crypt_keyslot_max() - helper to get number of supported keyslots
+ * crypt_get_active_device() - get active device info
+ * crypt_set/get_rng_type() - random/urandom RNG setting
+ * crypt_set_uuid() - explicit UUID change of existing device
+ * crypt_get_device_name() - get underlying device name
+
+ * Fix optional password callback handling.
+
+ * Allow to activate by internally cached volume key immediately after
+ crypt_format() without active slot (for temporary devices with
+ on-disk metadata)
+
+ * libcryptsetup is binary compatible with 1.1.x release and still
+ supports legacy API calls
+
+ * cryptsetup binary now uses only new API calls.
+
+ * Static compilation of both library (--enable-static) and cryptsetup
+ binary (--enable-static-cryptsetup) is now properly implemented by common
+ libtool logic.
+
+ Prior to this it produced miscompiled dynamic cryptsetup binary with
+ statically linked libcryptsetup.
+
+ The static binary is compiled as src/cryptsetup.static in parallel
+ with dynamic build if requested.
+
+Other changes
+~~~~~~~~~~~~~
+ * Fix default plain password entry from terminal in activate_by_passphrase.
+ * Initialize volume key from active device in crypt_init_by_name()
+ * Fix cryptsetup binary exit codes.
+ 0 - success, otherwise fail
+ 1 - wrong parameters
+ 2 - no permission
+ 3 - out of memory
+ 4 - wrong device specified
+ 5 - device already exists or device is busy
+ * Remove some obsolete info from man page.
+ * Add more regression tests for commands.
+ * Fix possible double free when handling master key file.
+ * Fix pkg-config use in automake scripts.
+ * Wipe iteration and salt after luksKillSlot in LUKS header.
+ * Rewrite file differ test to C (and fix it to really work).
+ * Do not query non-existent device twice (cryptsetup status /dev/nonexistent).
+ * Check if requested hash is supported before writing LUKS header.
+ * Fix problems reported by clang scan-build.
