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).

Preparing the tree for release
13
------------------------------
15
.. Was previously at http://bazaar-vcs.org/ReleaseChecklist
17
#. Make a local branch for preparing this release. (Only for the first
18
release in a series, otherwise you should already have a branch.) ::
20
bzr branch trunk prepare-1.14
24
22
#. Download the pqm plugin and install it into your ``~/.bazaar/plugins``::
26
24
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.
44
#. 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,
47
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
#. Send mail to the list with the key dates, who will be the release
59
manager, and the main themes or targeted bugs. Ask people to nominate
60
objectives, or point out any high-risk things that are best done early,
61
or that interact with other changes. This is called the metronome mail
62
and is described in `Development cycles <cycle.html>`_.
64
#. Make a local branch for preparing this release. (Only for the first
65
release in a series, otherwise you should already have a branch.) ::
67
bzr branch trunk prepare-1.14
69
#. Configure pqm-submit for this branch, with a section like this (where
70
x.y is the version to release).
26
#. Configure pqm-submit for this branch, with a section like this in

#. In the release branch, update ``version_info`` in ``./bzrlib/__init__.py``.
85
Make sure the corresponding milestone exists.
86
40
Double check that ./bzr ``_script_version`` matches ``version_info``. Check
87
the output of ``bzr --version``.
89
For beta releases use::
91
version_info = (2, 1, 0, 'beta', 1)
94
For release candidates use::
96
version_info = (2, 0, 1, 'candidate', 1)
99
Starting the release phase
100
--------------------------
102
#. Create a new milestone at <https://launchpad.net/bzr/x.y/+addmilestone>
103
for the beta release or release candidate if you haven't already.
41
the output of ``bzr --version``.
105
43
#. Add the date and release number to ``./NEWS``
107
Depending on whether you're doing a beta or a bugfix release, you'll
108
have to create a NEWS section for your release in the right
109
place. Most of the time, the new section is at the top of the file
110
(look what have been done for the various 2.0x and 2.1.0bx releases).
111
The rule is to keep the sections sorted by date. You'll need to be
112
cautious when merging back to trunk to respect that.
114
45
#. To check that all bugs mentioned in ``./NEWS`` are actually marked as
115
46
closed in Launchpad, you can run ``tools/check-newsbugs.py``::
117
48
./tools/check-newsbugs.py NEWS
119
(But note there can be some false positives, and this script may be
120
flaky <https://bugs.edge.launchpad.net/bzr/+bug/354985>. Don't let
121
this slow you down too much.)
123
50
#. Summarize into one or two paragraphs what's new in this release.
125
52
#. Commit these changes to the release branch, using a command like::
127
bzr commit -m "Release 1.14."
54
bzr commit -m "Release 1.14."
129
56
The diff before you commit will be something like::
131
58
=== modified file 'NEWS'
132
59
--- NEWS 2008-09-17 23:09:18 +0000

#. Change into the source directory and run ::
114
This also makes a zip file, which is easier to access on Microsoft
187
117
#. Now we'll try expanding this tarball and running the test suite
188
118
to check for packaging problems::
190
120
make check-dist-tarball
192
You may encounter failures while running the test suite caused
193
by your locally installed plugins. Use your own judgment to
194
decide if you can release with these failures. When in doubt,
195
disable the faulty plugins one by one until you get no more
199
Publishing the source tarball
200
-----------------------------
202
#. Go to the relevant milestone page in Launchpad.
204
#. Within that release, upload the source tarball and the GPG
205
signature. Or, if you prefer, use the
206
``tools/packaging/lp-upload-release`` script to do this.
209
Announcing the source freeze
210
----------------------------
212
#. Post to the ``bazaar`` list, saying that the source has been frozen.
213
This is the cue for platform maintainers and plugin authors to update
214
their code. This is done before the general public announcement of the
218

Publishing the release
219
124
----------------------
221
There is normally a delay of a few days after the source freeze to allow
222
for binaries to be built on various platforms. Once they have been built,
223
we have a releasable product. The next step is to make it generally
126
Now you have the releasable product. The next step is making it
224
127
available to the world.
129
#. In <https://launchpad.net/bzr/> click the "Release series" for this
130
series, to take you to e.g. <https://launchpad.net/bzr/1.14>. Then
131
click "Register a release", and add information about this release.
228
133
#. Within that release, upload the source tarball and zipfile and the GPG
229
134
signature. Or, if you prefer, use the
230
135
``tools/packaging/lp-upload-release`` script to do this.
232
#. Link from http://bazaar-vcs.org/SourceDownloads to the tarball and
235
#. Announce on the `Bazaar website <http://bazaar-vcs.org/>`_.
236
This page is edited via the lp:bzr-website branch. (Changes
237
pushed to this branch are refreshed by a cron job on escudero.)
239
#. Announce on the `Bazaar wiki <http://bazaar-vcs.org/Welcome>`_.
241
#. Check that the documentation for this release is available in
242
<http://doc.bazaar-vcs.org>. It should be automatically build when the

141
#. Check that the documentation for this release is available in
142
<http://doc.bazaar-vcs.org>. It should be automatically build when the
243
143
branch is created, by a cron script ``update-bzr-docs`` on
244
``escudero``. As of today (2009-08-27) ``igc`` manually updates the
245
pretty version of it.
248
147
Announcing the release
253
152
#. Make an announcement mail.
255
For release candidates or beta releases, this is sent to the ``bazaar``
256
list only to inform plugin authors and package or installer managers.
258
Once the installers are available, the mail can be sent to the
259
``bazaar-announce`` list too.
261
For final releases, it should also be cc'd to ``info-gnu@gnu.org``,
262
``python-announce-list@python.org``, ``bug-directory@gnu.org``.
264
In all cases, it is good to set ``Reply-To: bazaar@lists.canonical.com``,
265
so that people who reply to the announcement don't spam other lists.
154
For release candidates, this is sent to the ``bazaar-announce`` and
155
``bazaar`` lists. For final releases, it should also be cc'd to
156
``info-gnu@gnu.org``, ``python-announce-list@python.org``,
157
``bug-directory@gnu.org``. In both cases, it is good to set
158
``Reply-To: bazaar@lists.canonical.com``, so that people who reply to
159
the announcement don't spam other lists.
267
161
The announce mail will look something like this::
269
163
Subject: bzr x.yy released!

the version number in ``bzr`` and ``bzrlib/__init__.py``. Submit this
320
215
back into pqm for bzr.dev.
322
As soon as you change the version number in trunk, make sure you have
323
created the corresponding milestone to ensure the continuity in bug
324
targeting or nominating. Depending on the change, you may even have to
325
create a new series (if your change the major or minor release number), in
326
that case go to `Starting a cycle` and follow the instructions from there.
328
217
You should also merge (not pull) the release branch into
329
218
``lp:~bzr/bzr/current``, so that branch contains the current released code

Releases until the final one
333
----------------------------
335
Congratulations - you have made your first release. Have a beer
336
or fruit juice - it's on the house! If it was a beta, or
337
candidate, you're not finished yet. Another beta or candidate or
338
hopefully a final release is still to come.
340
The process is the same as for the first release. Goto `Starting the
341
release phase`_ and follow the instructions again. Some details change
342
between beta, candidate and final releases, but they should be
343
documented. If the instructions aren't clear enough, please fix them.
