+Bug-fix release 2.3
+~~~~~~~~~~~~~~~~~~~
+
+1. Add bmap file SHA1 checksum into the bmap file itself in order to improve
+   robustness of bmaptool. Now we verify bmap file integrity before using it,
+   and if it is corrupted on incomplete, we should be able to detect this.
+
+   This also means that if one changes the bmap file manually, bmaptool will
+   detect SHA1 mismatch and fail. In order to prevent the failure, one has to
+   update the bmap file's SHA1 by putting all ASCII 0 symbols (should be 40
+   zeroes) to the bmap file "sha1" attribute, and then generating SHA1 of that,
+   and putting the result back to the bmap file (by substituting the zeroes).
+
+2. Re-structure the bmap file layout and put information about mapped blocks
+   count at the beginning of the bmap XML file, not after the block map table.
+   This will make it possible to optimize bmap file parsing in the future.
+
+2. Make the test-suite work on btrfs.
