Recent releases


Changes: Lots of bugs were fixed. Improvements were made for booting from Intel IMSM metadata arrays. The default metadata version was changed to 1.2.


Changes: "--create --auto=mdp" was made to work for non-standard device names. Restarting of a "reshape" if it was stopped in the middle was fixed. A segfault when using v1 superblock was fixed. --write-mostly was made effective when re-adding a device to an array. Various minor fixes were made.


Changes: Assorted minor bugs relating to RAID4, verison-1 metadata, option parsing, spare migration, and more were fixed.


Changes: 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.


Changes: Bugfixes were made for the --monitor and --grow options to better support RAID6. The documentation was updated and some compiler warnings were fixed.
