To produce a `stable' release from the trunk:
-1. Update the release notes; make sure that the release date is
correct.
0. Make sure that the trunk builds in the release supervisor.
1. Branch the trunk, e.g., `svn cp .../trunk
.../branches/0.5-release'.
2. Switch to the branch, e.g., `svn switch .../branches/0.5-release'.
3. In `configure.ac', change `STABLE=0' into `STABLE=1' and commit.
4. In the release supervisor, add a one-time job to build
`.../branches/0.5-release'.
5. Make sure that the release succeeds.
6. Move the branch to a tag, e.g., `svn mv .../branches/0.5-release
.../tags/0.5'.
Note that the branch should not be used for maintenance; it should
be deleted after the release has been created. A maintenance
branch (e.g., `.../branches/0.5') should be created from the
original revision of the trunk (since maintenance releases should
also be tested first; hence, we cannot have `STABLE=1'). The same
procedure can then be followed to produce maintenance releases;
just substitute `.../branches/VERSION' for the trunk.
7. Switch back to the trunk.
8. Bump the version number in `configure.ac' (in AC_INIT).

<para>This release fixes a security bug in multi-user operation. It
was possible for derivations to cause the mode of files outside of the
Nix store to be changed to 444 (read-only but world-readable) by
creating hard links to those files (<link

logs (such as Hydra servers).</para></listitem>
