This document describes the processes for making and announcing a Bazaar
5
5
release, and managing the release process. This is just one phase of the
6
`overall development cycle <http://doc.bazaar-vcs.org/developers/cycle.html>`_,
7
but it's the most complex part.
8
This document gives a checklist you can follow from start to end in one
6
`overall development cycle

<http://doc.bazaar.canonical.com/developers/cycle.html>`_, (go re-read this
8
document to ensure it hasn't been updated since you last read it) but it's
11
If you're doing your first release you can follow this document and read
12
each step explanation. It's also a good practice to read it for any release
13
to ensure you don't miss a step and to update it as the release process
11
16
If you're helping the Release Manager (RM) for one reason or another, you
12
17
may notice that he didn't follow that document scrupulously. He may have
13
18
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).

#. PQM access rights (or you won't be able to land any change)
24
28
#. Download the pqm plugin and install it into your ``~/.bazaar/plugins``::
26
30
bzr branch lp:bzr-pqm ~/.bazaar/plugins/pqm
32
#. Alternatively, you can download and install ``lp:hydrazine`` (the main
33
difference is that hydrazine requires the branch to land to be hosted on
39
In this document, we're talking about source releases only, packages and
40
installers are built from this but we won't talk about them here.
42
Every release is part of a series, ``bzr-2.4.1`` is part of series ``2.4``.
44
We do two different kind of releases: the betas releases and the stable
45
releases for a given series.
47
For a given series, releases will be done to deliver new versions of bzr to
48
different kinds of users:
50
#. beta releases: named ``x.ybn`` where ``x.y`` is the series and ``n``
51
starts at 1 and is incremented. These releases are targeted to beta
52
testers who don't want to run from source but are interested in features
55
#. stable releases: name ``x.y.z`` where ``x.y.`` is the series and ``z``
56
starts at 0 and is incremented. These releases are targeted at people
57
that want bugfixes only and no new features.
60
Differences in the release process between beta and stable release will be
61
mentioned when needed.
66
As of July 2011, we maintain four series (and one that is about to be EOLed).
67
Concurrently releasing them all at the same time makes it harder to shorten
68
the delay between the source availability and the package building longer
69
than necessary (we delay the official announcement until most of our users
70
can install the new release).
72
In order to continue to do time-based releases, we need to plan the
73
releases by series to minimize the collisions. In the end, it's the Release
74
Manager call to decide whether he prefers to do all releases at once
75
though, so the rules presented here are a conservative approach.
77
We want to respect the following rules:
79
#. as much as possible releases should not disturb development, and
80
ongoing development should not disturb releases,
82
#. the most recent development series should release once a month during
83
the beta period (see `Development cycles <cycle.html>`_ for more
86
#. the most recent stable series should release every other month (based
87
on the amount of bug fixes, this can be shorter or longer depending on
90
#. previous series should release on a regular basis without interfering
91
with the most recent series with a decreasing order of priority (again
92
this should be based on bugs importance and user feedback),
94
#. the death of a series should be planned ahead of time. 6 months should
95
give enough time to our users to migrate to a more recent series. This
96
doesn't mean we will make a release at the end of the series, just that
97
before the end date we *could* possibly put out another release if
98
there was a sufficiently important fix. Beyond that date, we won't
99
even land changes on that branch (unless something causes a miraculous
102
#. there should not be more than 2 releases in the same week (but the
103
Release Manager is free to ignore this (get in touch with packagers
106
#. the series are aligned with Ubuntu releases for convenience since we
107
create a new series every 6 months. This means that we support the
108
stable series for 18 months. Note that we also propose the most recent
109
stable series via the stable PPA but that the SRU processs allow us to
110
reach a wider audience.
112
At the start of a series cycle
113
==============================
115
To start a new series cycle:
117
#. Create a new series ``x.y`` at <https://launchpad.net/bzr/+addseries>.
119
#. Add milestones at <https://launchpad.net/bzr/x.y/+addmilestone> to that
120
series for the beta releases and the stable series mentioning their
121
expected dates. Only the milestone associated to the next release in
122
this series should be left active to avoid clutter when targeting bugs.
124
#. If you made a new series, you will need to create a new pqm-controlled
125
branch for this release series. This branch will be used only from the
126
first non-beta release onwards. It needs to be created by a Canonical
127
sysadmin (ask the core devs for instructions or to do it for you).
129
#. Start a new release-notes file::
131
cd doc/en/release-notes
132
cp series-template.txt bzr-x.y.txt # e.g. bzr-2.3.txt
135
#. Start a new whats-new file::
138
cp template.txt bzr-x.y.txt # e.g. bzr-2.6.txt
141
#. Update ``doc/en/index.txt`` to point to the new whats-new file.
143
At the start of a release cycle
144
===============================
32
146
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
#. 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
148
#. Send mail to the list with the key dates, who will be the release
63
149
manager, and the main themes or targeted bugs. Ask people to nominate
64
150
objectives, or point out any high-risk things that are best done early,
65
151
or that interact with other changes. This is called the metronome mail
66
152
and is described in `Development cycles <cycle.html>`_.
68
#. Make a local branch for preparing this release. (Only for the first
69
release in a series, otherwise you should already have a branch.) ::
71
bzr branch trunk prepare-1.14
154
#. Make a local branch to prepare the release::
156
bzr branch lp:bzr/x.y x.y-dev
158
If you're doing your first beta release, branch from trunk::
160
bzr branch lp:bzr x.y-dev
162
Note that you will generally reuse the same branch for all releases in a
73
165
#. Configure pqm-submit for this branch, with a section like this (where
74
x.y is the version to release).
75

185
#. Add a new section at the top of the current release notes (in

``doc/en/release-notes``) about the new release, including its version
187
number and the headings from ``release-template.txt``.
189
#. Update the "What's New" documents in ``doc/en/whats-new``.
191
#. Make sure a milestone exists for your release and that it is active,
192
<https://launchpad.net/bzr/x.y> lists the existing milestones,

199
Doing a particular release
200
==========================
202
Update the source code
203
----------------------
205
#. Check that there is a milestone for the release you're doing. If there
206
is no milestone it indicates a process problem - make the milestone but
207
also mail the list to raise this issue in our process. Milestones are
208
found at <https://launchpad.net/bzr/+milestone/x.y.z>.
210
#. Merge into your branch all previous stable series fixes that haven't been
211
merged yet. For example, if you're releasing 2.6.x, make sure the fixes
212
on 2.5, 2.4, 2.3, etc have already been merged up::
216
and commit that merge in its own commit. This should happen only if the
217
devs landing changes in previous releases forgot to merge them up. Since
218
this can slow down the freeze, feel free to gently remind them about
219
their duties ;) If you feel unsafe resolving the conflicts or it's too
220
time consuming, contact the related devs and skip this merge.
88
222
#. In the release branch, update ``version_info`` in ``./bzrlib/__init__.py``.
89
223
Make sure the corresponding milestone exists.
90
224
Double check that ./bzr ``_script_version`` matches ``version_info``. Check
91
the output of ``bzr --version``.
225
the output of ``./bzr --version``.
93
227
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
--------------------------
106
#. 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.
109
#. 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
#. To check that all bugs mentioned in ``./NEWS`` are actually marked as
119
closed in Launchpad, you can run ``tools/check-newsbugs.py``::
121
./tools/check-newsbugs.py NEWS
123
(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.)
127
#. Summarize into one or two paragraphs what's new in this release.
229
version_info = (2, 6, 0, 'beta', SERIAL)
233
version_info = (2, 6, 0, 'beta', 1)
235
For stable releases use::
237
version_info = (2, 6, 0, 'final', 0)
239
#. Update the ``./doc/en/release-notes/`` section for this release.
241
Check that all news entries related to this release have been added in
242
the right section. For example, if you're releasing 2.6b2, the following
243
command should display a a single chuk diff for the 2.6b2 release::
245
bzr diff -rbzr-2.6b2.. doc/en/release-notes/bzr-2.6.txt
247
Fill out the date and a description of the release under the existing
248
header (the diff above will help you summarizing). If there isn't one,
249
follow the instructions above for using the ``release-template.txt`` file
250
and remind people that they should document their changes there ;)
252
See *2.6b1* or similar for an example of what this looks like.
254
#. Add or check the summary of the release into the "What's New" document.
256
If this is the first release in a new series make sure to update the
257
introduction mentioning:
259
* the date of this first release,
260
* until when the series is expected to be supported.
262
Looking at ``bzr annotate`` for previous series should give you the right
263
hints. The ``doc/en/_templates/index.html`` file should also be updated.
265
#. To check that all bugs mentioned in the release notes are actually
266
marked as closed in Launchpad, you can run
267
``tools/check-newsbugs.py``::
269
./tools/check-newsbugs.py doc/en/release-notes/bzr-x.y.txt
271
As of 2011-07-18, all bugs mentioned in the output of the script requires
272
some sort of intervention (either changing the status if it's not 'Fix
273
Released' or setting a different milestone if the bug hasn't been
274
fixed). A few false positives may remain in the older series, don't let
275
this slow you down too much. This script accepts options you may find
276
useful, use ``./tools/check-newsbugs.py`` to display its usage (``-w``
277
will open each bug in your browser for example).
279
#. For beta releases update the translation template::
281
BZR_PLUGIN_PATH=-site make po/bzr.pot
283
This is especially important for the final beta release which is when
284
translations are frozen and translators are requested (see `The final
285
beta - branching and translations`_) to make the translations.
287
#. For stable releases update the translations::
289
bzr merge lp:~bzr-core/bzr/bzr-translations-export-x.y
129
291
#. Commit these changes to the release branch, using a command like::
131
bzr commit -m "Release 1.14."
293
bzr commit -m "Release 2.3.1"
133
295
The diff before you commit will be something like::

Publishing the source tarball

-----------------------------
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.
424
#. Go to the relevant <https://launchpad.net/bzr/x.y> series page in Launchpad.
426
#. Create a release of the milestone, and upload the source tarball and
427
the GPG signature. Or, if you prefer, use the
428
``tools/packaging/lp-upload-release`` script to do this. Note that
429
this changes what the download widget on the Launchpad bzr home
430
page shows, so don't stop the release process yet, or platform binary
431
installers won't be made and the download list will stay very small!

Kick off the next cycle
436
-----------------------
438
From that point, there is no possible return, the tarball has been uploaded
439
so you can relax a bit.
441
You're still holding a "social" lock on the launchpad branch though. Until
442
your start the next cycle, nobody should land anything on this branch. If
443
they do, they either targeted the wrong branch or didn't update the news
444
file correctly, so the sooner the branch is opened again, the better.
446
This matters more for ``lp:bzr`` than for ``lp:bzr/x.y``, ``lp:bzr`` should
447
always be open for landing, so you should do `At the start of a release
448
cycle`_ as soon as possible (i.e. update the version number in ``bzr`` and
449
``bzrlib/__init__``, create/update the news files and create/update the
450
milestone for the next relase).
452
You may also need to do `At the start of a series cycle`_ if you're starting
455
The final beta - branching and translations
456
-------------------------------------------
458
A word of caution: the instructions above works well for all releases but
459
there is one special case that requires a bit more care: when you release
460
the *last* beta for a given ``x.y`` series (from trunk aka lp:bzr), you need
461
to setup *two* branches for the next cycle:
463
#. ``lp:bzr`` needs to be opened for the next *series* ``x.(y+1)``.
465
#. ``lp:bzr/x.y`` needs to be opened for the next *release* ``x.y.0`` in the
466
series. Since this is first real use of ``lp:bzr/x.y``, this is also the
467
deadline for the PQM branch to be created.
469
Both are important as ``lp:bzr`` should remain open so any change can be
470
landed, ``lp:bzr/x.y`` on the other hand should be ready to receive bug
473
``lp:bzr`` is generally more important as the bug fixes on ``lp:bzr/x.y``
474
won't be released sooner than a month from now whereas people may already
475
been waiting to land on ``lp:bzr``.
479
#. Open ``lp:bzr`` for ``x.(y+1)``
481
#. Create or update the ``x.y`` PQM branch based on whatever revision you
482
want to release. Since it takes time to create the PQM branch for the new
483
series you should plan to get it created a few days before you need it
484
and seed it with the revision from trunk you want to base your release of
485
(ask a LOSA for pulling this revision from trunk and pushing it to the
486
series branch (``lp:bzr/x.y``) when you're ready).
488
#. Release ``x.y.0`` from ``lp:bzr/x.y``
490
#. Open ``lp:bzr/x.y`` for bug fixes
492
You also need to ensure Launchpad is set up to import/export translations
493
for the new branch and inform translators.
495
#. Push the last beta release to a new branch::
497
bzr push lp:~bzr-core/bzr/bzr-translations-export-x.y
499
#. On the translations series synchronization settings page
500
<https://translations.launchpad.net/bzr/x.y/+translations-settings>
501
turn on ``Import template files`` then for exports click ``Choose a
502
target branch`` and point it at the branch you just pushed.
504
#. E-mail translators to announce that the forthcoming stable release of bzr
505
is ready for translations. Send to
506
``launchpad-translators@lists.launchpad.net`` and
507
``ubuntu-translators@lists.ubuntu.com``.
509
#. The series is now frozen for strings and API, see below for adding
510
that to the announcement.
213
512
Announcing the source freeze
214
513
----------------------------
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
515
#. Post to the ``bazaar@lists.canonical.com`` and
516
``bzr-packagers@list.launchpad.net`` lists, saying that the source has
517
been frozen. Be extra clear that this is only a *source* release targeted
518
at packagers and installer builders (see
519
<https://bugs.launchpad.net/launchpad/+bug/645084>). This is the cue for
520
platform maintainers and plugin authors to update their code. This is
521
done before the general public announcement of the release.
523
The freeze announcement generally guess the date of the official public
524
announcement, for the most recent stable series (the one supported by the
525
installers and most of the distributions) it's generally a few days after
526
the freeze. For older series supported only via SRUs for Ubuntu, we don't
527
control the process as tightly so guessing the date is not appropriate.
529
For the final beta release include in your announcement a notice of
530
API and translation freezes noting that public methods should not
531
be removed or changed and strings should not be added or changed.
533
#. Pause for a few days.
222
536
Publishing the release
223
537
----------------------
225
539
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,
540
for binaries to be built for various platforms. Once they have been built,
227
541
we have a releasable product. The next step is to make it generally
228
542
available to the world.
232
#. Within that release, upload the source tarball and zipfile and the GPG
233
signature. Or, if you prefer, use the
234
``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

#. Announce on the `Bazaar wiki <http://bazaar-vcs.org/Welcome>`_.
245
550
#. Check that the documentation for this release is available in
246
<http://doc.bazaar-vcs.org>. It should be automatically build when the
247
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.
551
<http://doc.bazaar.canonical.com>. It should be automatically build when
552
the branch is created, by a cron script ``update-bzr-docs`` on
553
``escudero``. When the first release is created in a new series, a branch
554
needs to be created on zhongshan::
556
ssh zhongshan.canonical.com
558
cd /srv/doc.bazaar.canonical.com/
559
bzr branch http://bazaar.launchpad.net/~bzr-pqm/bzr/2.6 bzr/bzr.2.6
561
And the ``bzr/bin/update-bzr-docs`` script needs to refer to it.
563
The ``lp:bzr-alldocs`` branch also needs to be updated when a new series
564
is introduced, see the ``README`` file there for more instructions
565
(looking at the branch history is also a good way to understand what
566
needs to be done and to document any policy changes).

656
Merging the released code back to trunk
319
657
---------------------------------------
321
Merge the release branch back into the trunk. Check that changes in NEWS
322
were merged into the right sections. If it's not already done, advance
323
the version number in ``bzr`` and ``bzrlib/__init__.py``. Submit this
324
back into pqm for bzr.dev.
659
Merge the release branch back into the trunk. The ``doc/en/release-notes``
660
changes should be merged into the right place because each release series
661
has its own release-notes file, but double-check.
663
If it's not already done, advance the version number in ``bzr`` and
664
``bzrlib/__init__.py``. Submit this back into pqm for bzr.dev.
326
666
As soon as you change the version number in trunk, make sure you have
327
667
created the corresponding milestone to ensure the continuity in bug
328
668
targeting or nominating. Depending on the change, you may even have to
329
669
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.
670
that case go to `At the start of a series cycle`_ and follow the
671
instructions from there.
332
You should also merge (not pull) the release branch into
333
``lp:~bzr/bzr/current``, so that branch contains the current released code

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.
677
Congratulations - you have made your first release. Have a beer or fruit

687
Getting the release into Ubuntu
688
-------------------------------
690
(Feel free to propose or add new sections here about what we should do to
691
get bzr into other places.)
693
For the currently-under-development release of Ubuntu, no special action
694
is needed: the release should be picked by Debian and synced from there into
697
Releases off stable bzr branches should go in to the ``-updates`` of the
698
Ubuntu release that originally contained that branch. (Ubuntu Lucid had
699
bzr 2.2.0, so should get every 2.2.x update.) This means going through
700
the `SRU (Stable Release Updates)
701
<https://wiki.ubuntu.com/StableReleaseUpdates>`__ process.
703
Since September 2010, bzr has received approval by the technical
704
board for the `MicroReleaseExceptions
705
<https://wiki.ubuntu.com/StableReleaseUpdates/MicroReleaseExceptions>`__
706
category so that whole bugfix releases can more easily be
709
Progress on these realeases is tracked on the `SRU wiki
710
<http://wiki.bazaar.canonical.com/UbuntuStableReleaseUpdates>`_
713
**After making a bzr stable-release release, nominate the most serious bug
714
for the appropriate Ubuntu release and subscribe the `ubuntu-sru` team.**
716
This requires a couple of tricks (please reconsider and tweak as things
717
evolves from one release to the other):
719
* create a distro task with the ``Also affects distribution`` button and
720
select ``bzr (Ubuntu)``.
722
* change the *URL* to point to ``ubuntu/+source/bzr`` instead of ``bzr``
723
(this is needed if you create the distro task but not if it exists
724
already). You should now be able to click the ``Nominate for release``
725
button and select the right Ubuntu release. As of September 2010, this
728
* ``quantal`` for the 2.6 series,
729
* ``precise`` for the 2.5 series,
730
* ``oneiric`` for the 2.4 series,
731
* ``natty`` for the 2.3 series,
732
* ``maverick`` for the 2.2 series,
733
* ``lucid`` for the 2.1 series,
735
* Subscribe the ``~ubuntu-sru`` team to the bug.
737
* Add a comment targeted to ``~ubuntu-sru`` explaining the expectations
738
(we are targeting running the test suite during the build which, as of
739
September 2010, fails for known reasons that are currently addressed).
740
Search for bugs tagged with ``sru`` for examples and don't forget to tag
741
the bug you selected.
