ChangeLog, main.c, resize2fs.c:

main.c (main): Check to make sure we can really resize this
  	filesystem.  If there are compatible feature sets that we don't
  	support, we need to abort.
  resize2fs.c: Change to use the new prototype required by
  	block_iterate2 (which uses blkcnt_t for the blockcount).
version.h, RELEASE-NOTES:
  Interim commit of changes to date.

+Added support for the EXT2_FEATURE_INCOMPAT_DIRNAME_SIZE feature,
+which means that e2fsprogs will ignore the high 8 bits of the
+directory entry's name_len field, so that it can be used for other
+purposes.
+
+Added support for the EXT2_FEATURE_RO_COMPAT_LARGE_FILE feature.
+E2fsprogs will now support filesystems with 64-bit sized files.
+
+Added support for the EXT2_FEATURE_COMPAT_DIR_PREALLOC feature.
+
 Added new program "e2label", contributed by Andries Brouwer.  E2label
 provides an easy-to-use interface to modify the filesystem label.
