This document describes the processes for making and announcing a Bazaar
5
release, and managing the release process. This is just one phase of the
6
`overall development cycle <http://doc.bazaar.canonical.com/developers/cycle.html>`_,
7
but it's the most complex part. This document gives a checklist you can
8
follow from start to end in one go.
10
If you're helping the Release Manager (RM) for one reason or another, you
11
may notice that he didn't follow that document scrupulously. He may have
12
good reasons to do that but he may also have missed some parts.
14
Follow the document yourself and don't hesitate to create the missing
15
milestones for example (we tend to forget these ones a lot).

At the start of a release cycle
29
===============================
31
To start a new release cycle:
33
#. If this is the first release for a given *x.y* then create a new
34
series at <https://launchpad.net/bzr/+addseries>. There is one series
35
for every *x.y* release.
37
#. If you made a new series, create a new pqm-controlled branch for this
38
release series, by asking a Canonical sysadmin. This branch means that
39
from the first release beta or candidate onwards, general development
40
continues on the trunk, and only specifically-targeted fixes go into
43
#. If you made a new series, add milestones at
44
<https://edge.launchpad.net/bzr/x.y/+addmilestone> to that series for
45
the beta release, release candidate and the final release, and their
48
#. Create a new milestone <https://edge.launchpad.net/bzr/x.y/+addmilestone>
49
and add information about this release. We will not use it yet, but it
50
will be available for targeting or nominating bugs.
52
#. Send mail to the list with the key dates, who will be the release
53
manager, and the main themes or targeted bugs. Ask people to nominate
54
objectives, or point out any high-risk things that are best done early,
55
or that interact with other changes. This is called the metronome mail
56
and is described in `Development cycles <cycle.html>`_.

79
``bzrlib/__init__.py`` file::
81
version_info = (x, y, z, 'dev', 0)
83
#. Add a new section at the top of ``NEWS`` about the new release,
84
including its version number and the headings from
85
``NEWS-template.txt``.
87
#. Update the "What's New" documents in ``doc/en/whats-new``.
89
#. Commit this and send it to PQM.
92
Doing a particular release
93
==========================
95
Update the source code
96
----------------------
98
#. Check that there is a milestone for the release you're doing. If there
99
is no milestone it indicates a process problem - make the milestone but
100
also mail the list to raise this issue in our process. Milestones are
101
found at <https://launchpad.net/bzr/+milestone/x.y.z>.
103
#. In the release branch, update ``version_info`` in ``./bzrlib/__init__.py``.
104
Make sure the corresponding milestone exists.
105
Double check that ./bzr ``_script_version`` matches ``version_info``. Check
106
the output of ``bzr --version``.
108
For beta releases use::
110
version_info = (2, 1, 0, 'beta', SERIAL)
114
version_info = (2, 1, 0, 'beta', 1)
116
For release candidates use::
118
version_info = (2, 0, 1, 'candidate', SERIAL)
120
For stable releases use::
122
version_info = (2, 1, 2, 'final', 0)
124
#. Update the ``./NEWS`` section for this release.
126
Fill out the date and a description of the release under the existing
127
header. If there isn't one, follow the above for using the NEWS
130
See *2.1.1* or similar for an example of what this looks like.
132
#. Add a summary of the release into the "What's New" document.
30
#. In the release branch, update ``version_info`` in
31
``./bzrlib/__init__.py``. Check the output of ``bzr --version``.
33
#. Add the date and release number to ``./NEWS``
134
35
#. To check that all bugs mentioned in ``./NEWS`` are actually marked as
135
36
closed in Launchpad, you can run ``tools/check-newsbugs.py``::
137
38
./tools/check-newsbugs.py NEWS
139
(But note there will be many false positives, and this script may be
140
flaky <https://bugs.edge.launchpad.net/bzr/+bug/354985>. Don't let
141
this slow you down too much.)
40
#. Summarize into one or two paragraphs what's new in this release.
143
42
#. Commit these changes to the release branch, using a command like::
145
bzr commit -m "Release 1.14."
44
bzr commit -m "Release 0.12rc1."
147
46
The diff before you commit will be something like::

190
appropriate release branch::

#. Now we'll try expanding this tarball and running the test suite

to check for packaging problems::

215
You may encounter failures while running the test suite caused
216
by your locally installed plugins. Use your own judgment to
217
decide if you can release with these failures. When in doubt,
218
disable the faulty plugins one by one until you get no more

Remember that PQM has just tested everything too, this step is

particularly testing that the pyrex extensions, which are updated

by your local pyrex version when you run make dist, are in good

Publishing the source tarball
228
-----------------------------
230
#. Go to the relevant milestone page in Launchpad.
232
#. Create a release of the milestone, and upload the source tarball and
233
the GPG signature. Or, if you prefer, use the
234
``tools/packaging/lp-upload-release`` script to do this. Note that
235
this changes what the download widget on the Launchpad bzr home
236
page shows, so don't stop the release process yet, or platform binary
237
installers won't be made and the download list will stay very small!
238

241
Announcing the source freeze
242
----------------------------
244
#. Post to the ``bazaar`` list, saying that the source has been frozen.
245
This is the cue for platform maintainers and plugin authors to update
246
their code. This is done before the general public announcement of the

Kick off the next cycle
251
-----------------------
253
#. To let developers work on the next release, do
254
`At the start of a release cycle` now.
256
#. Pause for a few days.
259
111
Publishing the release
260
112
----------------------
262
There is normally a delay of a few days after the source freeze to allow
263
for binaries to be built on various platforms. Once they have been built,
264
we have a releasable product. The next step is to make it generally
114
Now you have the releasable product. The next step is making it
265
115
available to the world.
267
#. Go to the release web page at <https://launchpad.net/bzr/x.y/x.y.z>
269
#. Announce on the `Bazaar website <http://bazaar.canonical.com/>`_.
270
This page is edited via the lp:bzr-website branch. (Changes
271
pushed to this branch are refreshed by a cron job on escudero.)
273
#. Check that the documentation for this release is available in
274
<http://doc.bazaar.canonical.com>. It should be automatically build when the
117
#. In <https://launchpad.net/bzr/> click the "Release series" for this
118
series, to take you to e.g. <https://launchpad.net/bzr/1.1>. Then
119
click "Register a release", and add information about this release.
121
#. Within that release, upload the source tarball and zipfile and the GPG
122
signature. Or, if you prefer, use the
123
``tools/packaging/lp-upload-release`` script to do this.
125
#. Link from http://bazaar-vcs.org/Download to the tarball and signature.
127
#. Announce on the `Bazaar home page <http://bazaar-vcs.org/>`_.
129
#. Check that the documentation for this release is available in
130
<http://doc.bazaar-vcs.org>. It should be automatically build when the
275
131
branch is created, by a cron script ``update-bzr-docs`` on
276
``escudero``. As of today (2009-08-27) ``igc`` manually updates the
277
pretty version of it.
280
135
Announcing the release
285
140
#. Make an announcement mail.
287
For release candidates or beta releases, this is sent to the ``bazaar``
288
list only to inform plugin authors and package or installer managers.
290
Once the installers are available, the mail can be sent to the
291
``bazaar-announce`` list too.
293
For final releases, it should also be cc'd to ``info-gnu@gnu.org``,
294
``python-announce-list@python.org``, ``bug-directory@gnu.org``.
296
In all cases, it is good to set ``Reply-To: bazaar@lists.canonical.com``,
297
so that people who reply to the announcement don't spam other lists.
299
The announce mail will look something like this::
301
Subject: bzr x.y.z released!
303
<<Summary paragraph from news>>
305
The Bazaar team is happy to announce availability of a new
306
release of the bzr adaptive version control system.
307
Bazaar is part of the GNU system <http://gnu.org/>.
309
Thanks to everyone who contributed patches, suggestions, and
312
Bazaar is now available for download from

314
for various systems will be available soon.
316
<<NEWS section from this release back to the last major release>>
318
Feel free to tweak this to your taste.
142
For release candidates, this is sent to the ``bazaar-announce`` and
143
``bazaar`` lists. For final releases, it should also be cc'd to
144
``info-gnu@gnu.org``, ``python-announce-list@python.org``,
145
``bug-directory@gnu.org``. In both cases, it is good to set
146
``Reply-To: bazaar@lists.canonical.com``, so that people who reply to
147
the announcement don't spam other lists.
149
The announce mail will look something like this:

Merging the released code back to trunk
347
194
---------------------------------------
349
The rule is to keep ``NEWS`` sections sorted by date. You'll need to
350
review the merge and make sure that that is respected.
352
196
Merge the release branch back into the trunk. Check that changes in NEWS
353
197
were merged into the right sections. If it's not already done, advance
354
198
the version number in ``bzr`` and ``bzrlib/__init__.py``. Submit this
355
199
back into pqm for bzr.dev.
357
As soon as you change the version number in trunk, make sure you have
358
created the corresponding milestone to ensure the continuity in bug
359
targeting or nominating. Depending on the change, you may even have to
360
create a new series (if your change the major or minor release number), in
361
that case go to `At the start of a release cycle` and follow the instructions from there.
363
201
You should also merge (not pull) the release branch into
364
202
``lp:~bzr/bzr/current``, so that branch contains the current released code
367
Releases until the final one

----------------------------
370
Congratulations - you have made your first release. Have a beer
371
or fruit juice - it's on the house! If it was a beta, or
372
candidate, you're not finished yet. Another beta or candidate or
373
hopefully a final release is still to come.
375
The process is the same as for the first release. Goto `Doing a
376
particular release`_ and follow the instructions again. Some details change
377
between beta, candidate and final releases, but they should be
378
documented. If the instructions aren't clear enough, please fix them.
