+[[!toggleable text="""
+   * Free space checking is now done, for transfers of data for keys
+     that have free space metadata. (Notably, not for SHA* keys generated
+     with git-annex 0.2x or earlier.) The code is believed to work on
+     Linux, FreeBSD, and OSX; check compile-time messages to see if it
+     is not enabled for your OS.
+   * Add annex.diskreserve config setting, to control how much free space
+     to reserve for other purposes and avoid using (defaults to 1 mb).
+   * Add --fast flag, that can enable less expensive, but also less thorough
+     versions of some commands.
+   * fsck: In fast mode, avoid checking checksums.
+   * unused: In fast mode, just show all existing temp files as unused,
+     and avoid expensive scan for other unused content.
+   * migrate: Support migrating v1 SHA keys to v2 SHA keys with
+     size information that can be used for free space checking.
+   * Fix space leak in fsck and drop commands.
+   * migrate: Bugfix for case when migrating a file results in a key that
+     is already present in .git/annex/objects.
+   * dropunused: Significantly sped up; only read unused log file once."""]]

-   * Support ssh remotes with a port specified.
-   * whereis: New subcommand to show where a file's content has gotten to.
-   * Rethink filename encoding handling for display. Since filename encoding
-     may or may not match locale settings, any attempt to decode filenames
-     will fail for some files. So instead, do all output in binary mode."""]]
