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 <cycle.html>`_, but it's the most complex part.
7
This document gives a checklist you can follow from start to end in one
5
release, and managing the release process. This is just one phase of the
6
`overall development cycle
7
<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
16
If you're helping the Release Manager (RM) for one reason or another, you
17
may notice that he didn't follow that document scrupulously. He may have
18
good reasons to do that but he may also have missed some parts.
13
Starting the release phase
14
--------------------------
16
When it's time to make the release candidate:
18
#. We create a new pqm-controlled branch for this release series, by
19
asking a Canonical sysadmin.
20
This branch means that from the first release candidate onwards,
21
general development continues on the trunk, and only
22
specifically-targetted fixes go into the release.
24
#. Register the branch at <https://launchpad.net/products/bzr/+addbranch>
26
#. Make a release candidate.
29
Preparing the tree for release
30
------------------------------
32
#. Make a local branch for preparing this release. (Only for the first
33
release in a series, otherwise you should already have a branch.) ::
35
bzr branch trunk prepare-1.14
26
#. PQM access rights (or you won't be able to land any change)
37
28
#. Download the pqm plugin and install it into your ``~/.bazaar/plugins``::
39
30
bzr branch lp:bzr-pqm ~/.bazaar/plugins/pqm
41
#. Configure pqm-submit for this branch, with a section like this in
42
``~/.bazaar/locations.conf``::
44
[/home/mbp/bzr/prepare-1.14]
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
===============================
146
To start a new release cycle:
148
#. Send mail to the list with the key dates, who will be the release
149
manager, and the main themes or targeted bugs. Ask people to nominate
150
objectives, or point out any high-risk things that are best done early,
151
or that interact with other changes. This is called the metronome mail
152
and is described in `Development cycles <cycle.html>`_.
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
165
#. Configure pqm-submit for this branch, with a section like this (where
166
``x.y`` is the series for your release). **Or use hydrazine for easier
167
setup** ``~/.bazaar/locations.conf``::

#. Update the version number in the ``bzr`` script, and the
181
``bzrlib/__init__.py`` file::
183
version_info = (x, y, z, 'dev', 0)
185
#. Add a new section at the top of the current release notes (in
186
``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,

#. Commit this and send it to PQM.
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.
54
222
#. In the release branch, update ``version_info`` in ``./bzrlib/__init__.py``.
223
Make sure the corresponding milestone exists.
55
224
Double check that ./bzr ``_script_version`` matches ``version_info``. Check
56
the output of ``bzr --version``.
58
#. Add the date and release number to ``./NEWS``
60
#. To check that all bugs mentioned in ``./NEWS`` are actually marked as
61
closed in Launchpad, you can run ``tools/check-newsbugs.py``::
63
./tools/check-newsbugs.py NEWS
65
(But note there can be some false positives, and this script may be
67
<https://bugs.edge.launchpad.net/bzr/+bug/354985>. Don't let this
68
slow you down too much.)
70
#. Summarize into one or two paragraphs what's new in this release.
225
the output of ``./bzr --version``.
227
For beta releases use::
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
72
291
#. Commit these changes to the release branch, using a command like::
74
bzr commit -m "Release 1.14."
293
bzr commit -m "Release 2.3.1"
76
295
The diff before you commit will be something like::

376
created). If it doesn't, double-check that you created (and pushed) this

This also makes a zip file, which is easier to access on Microsoft

138
395
to check for packaging problems::
140
make check-dist-tarball
397
make check-dist-tarball | subunit2pyunit
399
You may encounter failures while running the test suite caused by your
400
locally installed plugins. Use your own judgment to decide if you can
401
release with these failures. When in doubt, disable the faulty plugins
402
one by one until you get no more failures. Alternatively, you can use
403
``BZR_DISABLE_PLUGINS`` or ``BZR_PLUGIN_PATH=-site`` to disable one or
406
Until <http://pad.lv/839461> is fixed, you may encounter issues if you
407
cut a release for old stable branches (<= 2.2) and use a more recent
408
OS/distro. If that's the case, check the bug status and use the following
409
workaround if no fix is available::
411
export TTPATH=<local branch of lp:testtools -r 0.9.2>
412
export SUPATH=<local branch of lp:subunit -r 0.0.6>

Remember that PQM has just tested everything too, this step is
416
particularly testing that the pyrex extensions, which are updated
417
by your local pyrex version when you run make dist, are in good
421
Publishing the source tarball
422
-----------------------------
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!
432
<https://bugs.launchpad.net/launchpad/+bug/586445>
435
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.
512
Announcing the source freeze
513
----------------------------
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.
143
536
Publishing the release
144
537
----------------------
146
Now you have the releasable product. The next step is making it
539
There is normally a delay of a few days after the source freeze to allow
540
for binaries to be built for various platforms. Once they have been built,
541
we have a releasable product. The next step is to make it generally
147
542
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.
153
#. Within that release, upload the source tarball and zipfile and the GPG
154
signature. Or, if you prefer, use the
155
``tools/packaging/lp-upload-release`` script to do this.
157
#. Link from http://bazaar-vcs.org/Download to the tarball and signature.
159
#. Announce on the `Bazaar home page <http://bazaar-vcs.org/>`_.
161
#. Check that the documentation for this release is available in

branch is created, by a cron script ``update-bzr-docs`` on

#. Go to the release web page at <https://launchpad.net/bzr/x.y/x.y.z>
546
#. Announce on the `Bazaar website <http://bazaar.canonical.com/>`_. This

page is edited in ``build.py`` in the lp:bzr-website branch. (Changes
548
pushed to this branch are refreshed by a cron job on escudero.)
550
#. Check that the documentation for this release is available in
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).
167
568
Announcing the release
168
569
----------------------
172
573
#. Make an announcement mail.
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.
575
For beta releases, this is sent to the ``bazaar@lists.canonical.com`` and
576
``bazaar-announce@lists.canonical.com`` lists.
578
For stable releases (excluding SRUs which are for older stable releases),
579
it should also be cc'd to ``info-gnu@gnu.org``,
580
``python-announce-list@python.org``, ``bug-directory@gnu.org``.
582
In all cases, it is good to set ``Reply-To: bazaar@lists.canonical.com``,
583
so that people who reply to the announcement don't spam other lists.
181

ensuring the new topic text keeps the project name, web site link, etc.
207

``Administration`` box in the lower right area of the page:
625
* Edit the project: This is where most of the URLs proposed in the
626
``Links`` box are edited. This should rarely change except for the URLs
627
related to the latest stable release.
629
* New announcement: When doing a release, put the summary of the release
630
(you can't embed URLs there, the moderation staff remove them). Users
631
can still access the releases notes via the ``Release Notes`` URL in
632
the ``Links`` box in the upper right area of the page. When doing the
633
first stable release in a series, delete the ``Unstable installers``
634
<https://launchpad.net/bzr/x.y/x.ybn> and ``Unstable source tarball``

Merging the released code back to trunk
229
657
---------------------------------------
231
Merge the release branch back into the trunk. Check that changes in NEWS
232
were merged into the right sections. If it's not already done, advance
233
the version number in ``bzr`` and ``bzrlib/__init__.py``. Submit this
234
back into pqm for bzr.dev.
236
You should also merge (not pull) the release branch into
237
``lp:~bzr/bzr/current``, so that branch contains the current released code
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.
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.
666
As soon as you change the version number in trunk, make sure you have
667
created the corresponding milestone to ensure the continuity in bug
668
targeting or nominating. Depending on the change, you may even have to
669
create a new series (if your change the major or minor release number), in
670
that case go to `At the start of a series cycle`_ and follow the
671
instructions from there.
674
Releases until the final one
675
----------------------------
677
Congratulations - you have made your first release. Have a beer or fruit
678
juice - it's on the house! If it was a beta, you're not finished
679
yet. Another beta or hopefully a stable release is still to come.
681
The process is the same as for the first release. Goto `Doing a particular
682
release`_ and follow the instructions again. Some details change between
683
beta and stable releases, but they should be documented. If the instructions
684
aren't clear enough, please fix them.
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.
