cryptsetup (2:2.6.1-1) unstable; urgency=medium

  * New upstream bugfix release.
  * d/README.Debian: Explicitly set cswap1's device type to 'plain'.
    (Closes: #1025136)
  * d/control: Update standards version to 4.6.2, no changes needed.
  * d/clean: Add some gitignore(5)'d files. (Closes: #1026838)
  * cryptgnupg-sc hook: Look terminfo file in /usr/share/terminfo in adition
    to /lib/terminfo, see #1028202. (Closes: 1028234)
  * d/copyright: Bump copyright years.

cryptsetup (2:2.6.0-2) unstable; urgency=low

  * libcryptsetup-dev: Add 'Depends: libargon2-dev, libblkid-dev,
    libdevmapper-dev, libjson-c-dev, libssl-dev, uuid-dev' to account for
    libcryptsetup.pc's Requires.private.  Closes: #1025054.

cryptsetup (2:2.6.0-1) unstable; urgency=low

  * New upstream release 2.6.0.

cryptsetup (2:2.6.0~rc0-1) experimental; urgency=medium

  * New upstream release candidate 2.6.0, introducing support for handling
    macOS FileVault2 devices (FVAULT2).  The new version of FileVault based on
    the APFS filesystem used in recent macOS versions is currently not
    supported: only the (legacy) FileVault2 format based on Core Storage and
    HFS+ filesystem (introduced in MacOS X 10.7 Lion) is supported.  Moreover
    header formatting and changes are not supported; cryptsetup never changes
    the metadata on the device.
    Closes: #923513.
  * Update d/copyright for 2:2.6.0~rc0-1.
  * Ship cryptsetup-fvault2Dump(8) and cryptsetup-fvault2Open(8) to
    cryptsetup-bin binary package.
  * Update d/libcryptsetup12.symbols for 2:2.6.0~rc0-1.
  * Add 'fvault2' flag to crypttab(5) to force detection of Apple's FileVault2
    volumes.
  * d/rules: Add new target execute_before_dh_auto_test so blhc ignores
    compilations of tests/*.c.
  * d/u/metadata: Set 'Security-Contact' upstream metadata field.
