Release Notes: Assorted minor bugs relating to RAID4, verison-1 metadata, option parsing, spare migration, and more were fixed.
Release Notes: Various bugfixes were made. It is now possible to hot-add a drive to a linear array (this used to work but there were bugs which recent kernel changes have tripped over). A new "--auto-detect" mode was added, which is equivalent to the "raidautorun" that some distros include.
Release Notes: Bugfixes were made for the --monitor and --grow options to better support RAID6. The documentation was updated and some compiler warnings were fixed.
Release Notes: This release fixes a bug which meant that "bitmap=xxx" in mdadm.conf was not handled properly and a bug which caused an infinite loop when doing auto-assembly in certain cases in which arrays couldn't be assembled. The documentation has been updated.
Release Notes: Compiling fixes were done. Minor improvements were made to mdassemble, bitmap creation, and the documentation.
Release Notes: This release fixed a recent breakage of starting degraded arrays and included a few minor documentation updates.
Release Notes: Various compiler warnings fixes, various makefile fixes, and other fixes were made. The most significant fix is to remove a memory leak in --monitor mode that was introduced in 2.5.
Release Notes: A significant new feature is auto assembly, which causes mdadm to search for components of md arrays and assemble what it finds. This works in conjunction with a new --homehost option, which can tag arrays to tell which host they should be assembled on. Also, if no DEVICE list is given, "DEVICE partitions" is assumed. The configuration file can now provide a "mailfrom address". A copy of /proc/mdstat is included with email from --monitor mode. Assorted other updates were made.
Release Notes: Full support for raid5-reshape (adding a drive to RAID5) is available in Linux 2.6.17-rc1 and later. The --monitor option is allowed to work with arrays with more than 28 devices. Symlinks in /dev are handled better. "bitmap=" support was added in mdadm.conf for assembling arrays with separate bitmaps. The documentation was updated.
