release, and managing the release process. This is just one phase of the
6
`overall development cycle <cycle.html>`_, but it's the most complex part.

This document gives a checklist you can follow from start to end in one
11
If you're helping the Release Manager (RM) for one reason or another, you
12
may notice that he didn't follow that document scrupulously. He may have
13
good reasons to do that but he may also have missed some parts.
15
Follow the document yourself and don't hesitate to create the missing
16
milestones for example (we tend to forget these ones a lot).
24
#. Download the pqm plugin and install it into your ``~/.bazaar/plugins``::
26
bzr branch lp:bzr-pqm ~/.bazaar/plugins/pqm
32
To start a new release cycle:
34
#. Create a new series at <https://launchpad.net/bzr/+addseries>. There is one
35
series for every *x.y* release.
37
#. Go to the series web page at <https://launchpad.net/bzr/x.y>
39
#. Create a new release at
40
<https://launchpad.net/bzr/x.y/+addrelease> and add
41
information about this release. We will not use it yet, but it
42
will be available for targeting or nominating bugs.
13
Starting the release phase
14
--------------------------
16
When it's time to make the release candidate:
44
18
#. We create a new pqm-controlled branch for this release series, by
45
asking a Canonical sysadmin.
46
This branch means that from the first release beta or candidate onwards,
19
asking a Canonical sysadmin.
20
This branch means that from the first release candidate onwards,
47
21
general development continues on the trunk, and only
48
specifically-targeted fixes go into the release branch.
50
#. Add milestones at <https://edge.launchpad.net/bzr/x.y/+addmilestone> to
51
that series for the beta release, release candidate and the final release,
52
and their expected dates.
54
#. Update the version number in the ``bzr`` script, and the
55
``bzrlib/__init__.py`` file. Make sure there is always a corresponding
56
milestone when you change that version number.
58
#. Add a new section at the top of ``NEWS`` about the new release,
59
including its version number and the headings from
60
``NEWS-template.txt``.
62
#. Send mail to the list with the key dates, who will be the release
63
manager, and the main themes or targeted bugs. Ask people to nominate
64
objectives, or point out any high-risk things that are best done early,
65
or that interact with other changes. This is called the metronome mail
66
and is described in `Development cycles <cycle.html>`_.
68
#. Make a local branch for preparing this release. (Only for the first
22
specifically-targetted fixes go into the release.
24
#. Register the branch at <https://launchpad.net/products/bzr/+addbranch>
26
#. Make a release candidate.

Preparing the tree for release
30
------------------------------
32
#. Make a local branch for preparing this release. (Only for the first
69
33
release in a series, otherwise you should already have a branch.) ::
71
35
bzr branch trunk prepare-1.14
73
#. Configure pqm-submit for this branch, with a section like this (where
74
x.y is the version to release).
37
#. Download the pqm plugin and install it into your ``~/.bazaar/plugins``::
39
bzr branch lp:bzr-pqm ~/.bazaar/plugins/pqm
41
#. Configure pqm-submit for this branch, with a section like this in
75
42
``~/.bazaar/locations.conf``::
77
[/home/mbp/bzr/prepare-x.y]
44

88
54
#. In the release branch, update ``version_info`` in ``./bzrlib/__init__.py``.
89
Make sure the corresponding milestone exists.
90
55
Double check that ./bzr ``_script_version`` matches ``version_info``. Check
91
the output of ``bzr --version``.
93
For beta releases use::
95
version_info = (2, 1, 0, 'beta', 1)
98
For release candidates use::
100
version_info = (2, 0, 1, 'candidate', 1)
103
Starting the release phase
104
--------------------------

#. Create a new milestone at <https://launchpad.net/bzr/x.y/+addmilestone>
107
for the beta release or release candidate if you haven't already.
56
the output of ``bzr --version``.
109
58
#. Add the date and release number to ``./NEWS``
111
Depending on whether you're doing a beta or a bugfix release, you'll
112
have to create a NEWS section for your release in the right
113
place. Most of the time, the new section is at the top of the file
114
(look what have been done for the various 2.0x and 2.1.0bx releases).
115
The rule is to keep the sections sorted by date. You'll need to be
116
cautious when merging back to trunk to respect that.
118
60
#. To check that all bugs mentioned in ``./NEWS`` are actually marked as
119
61
closed in Launchpad, you can run ``tools/check-newsbugs.py``::
121
63
./tools/check-newsbugs.py NEWS
123
65
(But note there can be some false positives, and this script may be
124
flaky <https://bugs.edge.launchpad.net/bzr/+bug/354985>. Don't let
125
this slow you down too much.)
67
<https://bugs.edge.launchpad.net/bzr/+bug/354985>. Don't let this
68
slow you down too much.)
127
70
#. Summarize into one or two paragraphs what's new in this release.
129
72
#. Commit these changes to the release branch, using a command like::
131
bzr commit -m "Release 1.14."
74
bzr commit -m "Release 1.14."
133
76
The diff before you commit will be something like::

134
This also makes a zip file, which is easier to access on Microsoft
191
137
#. Now we'll try expanding this tarball and running the test suite
192
138
to check for packaging problems::
194
140
make check-dist-tarball
196
You may encounter failures while running the test suite caused
197
by your locally installed plugins. Use your own judgment to
198
decide if you can release with these failures. When in doubt,
199
disable the faulty plugins one by one until you get no more
203
Publishing the source tarball
204
-----------------------------
206
#. Go to the relevant milestone page in Launchpad.
208
#. Within that release, upload the source tarball and the GPG
209
signature. Or, if you prefer, use the
210
``tools/packaging/lp-upload-release`` script to do this.
213
Announcing the source freeze
214
----------------------------
216
#. Post to the ``bazaar`` list, saying that the source has been frozen.
217
This is the cue for platform maintainers and plugin authors to update
218
their code. This is done before the general public announcement of the

Publishing the release
223
144
----------------------
225
There is normally a delay of a few days after the source freeze to allow
226
for binaries to be built on various platforms. Once they have been built,
227
we have a releasable product. The next step is to make it generally
146
Now you have the releasable product. The next step is making it
228
147
available to the world.
149
#. In <https://launchpad.net/bzr/> click the "Release series" for this
150
series, to take you to e.g. <https://launchpad.net/bzr/1.14>. Then
151
click "Register a release", and add information about this release.
232
153
#. Within that release, upload the source tarball and zipfile and the GPG
233
154
signature. Or, if you prefer, use the
234
155
``tools/packaging/lp-upload-release`` script to do this.
236
#. Link from http://bazaar-vcs.org/SourceDownloads to the tarball and
239
#. Announce on the `Bazaar website <http://bazaar-vcs.org/>`_.
240
This page is edited via the lp:bzr-website branch. (Changes
241
pushed to this branch are refreshed by a cron job on escudero.)
243
#. Announce on the `Bazaar wiki <http://bazaar-vcs.org/Welcome>`_.
245
#. Check that the documentation for this release is available in

#. Check that the documentation for this release is available in

<http://doc.bazaar-vcs.org>. It should be automatically build when the
247
163
branch is created, by a cron script ``update-bzr-docs`` on
248
``escudero``. As of today (2009-08-27) ``igc`` manually updates the
249
pretty version of it.
252
167
Announcing the release
257
172
#. Make an announcement mail.
259
For release candidates or beta releases, this is sent to the ``bazaar``
260
list only to inform plugin authors and package or installer managers.
262
Once the installers are available, the mail can be sent to the
263
``bazaar-announce`` list too.
265
For final releases, it should also be cc'd to ``info-gnu@gnu.org``,
266
``python-announce-list@python.org``, ``bug-directory@gnu.org``.
268
In all cases, it is good to set ``Reply-To: bazaar@lists.canonical.com``,
269
so that people who reply to the announcement don't spam other lists.
174
For release candidates, this is sent to the ``bazaar-announce`` and
175
``bazaar`` lists. For final releases, it should also be cc'd to
176
``info-gnu@gnu.org``, ``python-announce-list@python.org``,
177
``bug-directory@gnu.org``. In both cases, it is good to set
178
``Reply-To: bazaar@lists.canonical.com``, so that people who reply to
179
the announcement don't spam other lists.
271
181
The announce mail will look something like this::
273
183
Subject: bzr x.yy released!

the version number in ``bzr`` and ``bzrlib/__init__.py``. Submit this
324
234
back into pqm for bzr.dev.
326
As soon as you change the version number in trunk, make sure you have
327
created the corresponding milestone to ensure the continuity in bug
328
targeting or nominating. Depending on the change, you may even have to
329
create a new series (if your change the major or minor release number), in
330
that case go to `Starting a cycle` and follow the instructions from there.
332
236
You should also merge (not pull) the release branch into
333
237
``lp:~bzr/bzr/current``, so that branch contains the current released code
336
Releases until the final one
337
----------------------------
339
Congratulations - you have made your first release. Have a beer
340
or fruit juice - it's on the house! If it was a beta, or
341
candidate, you're not finished yet. Another beta or candidate or
342
hopefully a final release is still to come.
344
The process is the same as for the first release. Goto `Starting the
345
release phase`_ and follow the instructions again. Some details change
346
between beta, candidate and final releases, but they should be
347
documented. If the instructions aren't clear enough, please fix them.
244
To start a new release cycle:
246
#. Send mail to the list with the key dates, who will be the release
247
manager, and the main themes or targeted bugs. Ask people to nominate
248
objectives, or point out any high-risk things that are best done early,
249
or that interact with other changes.
251
#. Add a new "series" in Launchpad at <https://launchpad.net/bzr/+addseries>.
252
There is one series for every *x.y* release.
254
#. Add milestones to that series for the release candidate and the final
255
release, and their expected dates.
257
#. Deactivate old releases and their milestones.
259
#. Update the version number in the ``bzr`` script, and the
260
``bzrlib/__init__.py`` file.
