+Subject: [PATCH] Remove LUKS2 encryption data size restriction.
+
+LUKS2 encryption with data shift required remaining
+data size (size remaining after substracting --reduce-data-size value)
+to be at least --reduce-data-size. This was wrong. Remaining
+data size restriction should be correctly at least single sector
+(whatever sector size is selected or auto-detected).

+Subject: [PATCH 5/5] Fix internal crypt segment compare routine.
+
+The function is supposed to check if manipulated
+active dm-crypt device matches the on-disk metadata.
+Unfortunately it did not take into account differences
+between normal cipher specification (aes-xts-plain64)
+and capi format specification (capi:xts(aes)-plain64).
+The internal query function always converted capi format
+in normal format and therefor failed if capi format was
+used in metadata.
+
+Fixes: #759.
