As of October 2010, we mantain four series. Concurrently releasing them
34
all at the same time makes it harder to shorten the delay between the
35
source availability and the package building longer than necessary (we
36
delay the official announcement until most of our users can install the new

In order to continue to do time-based releases, we need to plan the
40
releases by series to minimize the collisions. In the end, it's the Release
41
Manager call to decide whether he prefers to do all releases at once
42
though, so the rules presented here are a conservative approach.
44
We want to respect the following rules::
46
#. as much as possible releases should not disturb development, and
47
ongoing development should not disturb releases,
49
#. the most recent development series should release once a month during
50
the beta period (see `Development cycles <cycle.html>`_ for more
53
#. the most recent stable series should release every other month (based
54
on the amount of bug fixes, this can be shorter or longer depending on
57
#. previous series should relesase on a regular basis without interfering
58
with the most recent series with a decreasing order of priority (again
59
this should be based on bugs importance and user feedback),
61
#. the death of a series should be planned ahead of time. 6 months should
62
give enough time to our users to migrate to a more recent series. This
63
doesn't mean we will make a release at the end of the series, just that
64
before the end date we _could_ possibly put out another release if
65
there was a sufficiently important fix. Beyond that date, we won't
66
even land changes on that branch (unless something causes a miraculous
69
#. there should not be more than 2 releases in the same week (but the
70
Release Manager is free to ignore this (get in touch with packagers
73
#. the series are aligned with Ubuntu releases for convenience since we
74
create a new series every 6 months. This means that we support the
75
stable series for 18 months. Note that we also propose the most recent
76
stable series via the ppa, so whether we keep supporting LTS directly
77
or via the ppa is still an open question.
80
At the start of a release cycle
81
===============================
32
83
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
85
#. If this is the first release for a given *x.y* then create a new
86
series at <https://launchpad.net/bzr/+addseries>. There is one series
87
for every *x.y* release.
89
#. If you made a new series, create a new pqm-controlled branch for this
90
release series, by asking a Canonical sysadmin. This branch means that
91
from the first release beta or candidate onwards, general development
92
continues on the trunk, and only specifically-targeted fixes go into
95
#. If you made a new series, add milestones at
96
<https://launchpad.net/bzr/x.y/+addmilestone> to that series for
97
the beta release, release candidate and the final release, and their
100
#. Create a new milestone <https://launchpad.net/bzr/x.y/+addmilestone>
101
and add information about this release. We will not use it yet, but it
42
102
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
104
#. Send mail to the list with the key dates, who will be the release
63
105
manager, and the main themes or targeted bugs. Ask people to nominate
64

``bzrlib/__init__.py`` file::
133
version_info = (x, y, z, 'dev', 0)
135
#. If you made a new series, then start a new release-notes file::
137
cd doc/en/release-notes
138
cp series-template.txt bzr-x.y.txt # e.g. bzr-2.3.txt
141
#. Add a new section at the top of the current release notes (in
142
``doc/en/release-notes``) about the new release, including its version
143
number and the headings from ``release-template.txt``.
145
#. Update the "What's New" documents in ``doc/en/whats-new``.
147
#. Commit this and send it to PQM.
150
Doing a particular release
151
==========================
153
Update the source code
154
----------------------
156
#. Check that there is a milestone for the release you're doing. If there
157
is no milestone it indicates a process problem - make the milestone but
158
also mail the list to raise this issue in our process. Milestones are
159
found at <https://launchpad.net/bzr/+milestone/x.y.z>.
88
161
#. In the release branch, update ``version_info`` in ``./bzrlib/__init__.py``.
89
162
Make sure the corresponding milestone exists.
90
163
Double check that ./bzr ``_script_version`` matches ``version_info``. Check
93
166
For beta releases use::
168
version_info = (2, 1, 0, 'beta', SERIAL)
95
172
version_info = (2, 1, 0, 'beta', 1)
98
174
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.
176
version_info = (2, 0, 1, 'candidate', SERIAL)
178
For stable releases use::
180
version_info = (2, 1, 2, 'final', 0)
182
#. Update the ``./doc/en/release-notes/`` section for this release.
184
Fill out the date and a description of the release under the existing
185
header. If there isn't one, follow the instructions above for using the
186
``release-template.txt`` file.
188
See *2.1.1* or similar for an example of what this looks like.
190
#. Add a summary of the release into the "What's New" document.
192
#. To check that all bugs mentioned in the release notes are actually
193
marked as closed in Launchpad, you can run
194
``tools/check-newsbugs.py``::
196
./tools/check-newsbugs.py doc/en/release-notes/bzr-x.y.txt
198
(As of 2011-03-10, only a few false positives remain. Don't let this slow
129
201
#. Commit these changes to the release branch, using a command like::
131
bzr commit -m "Release 1.14."
203
bzr commit -m "Release 2.3.1"
133
205

There are several kinds of modifications that could be done there via the
428
``Administration`` box in the lower right area of the page:
430
* Edit the project: This is where most of the URLs proposed in the
431
``Links`` box are edited. This should rarely change except for the URLs
432
related to the latest stable release.
434
* New announcement: When doing a release (beta, candidates, final), put the
435
summary of the release (you can't embed URLs there, the moderation staff
436
remove them). Users can still access the releases notes via the ``Release
437

466
Merging the released code back to trunk
319
467
---------------------------------------
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.
469
Merge the release branch back into the trunk. The
470
``doc/en/release-notes`` changes should be merged into the right place
471
because each release series has its own release-notes file, but
474
If it's not already done, advance the version number in ``bzr`` and
475
``bzrlib/__init__.py``. Submit this back into pqm for bzr.dev.
326
477
As soon as you change the version number in trunk, make sure you have
327
478
created the corresponding milestone to ensure the continuity in bug
328
479
targeting or nominating. Depending on the change, you may even have to
329
480
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.
481
that case go to `At the start of a release cycle` and follow the instructions from there.

501
Getting the release into Ubuntu
502
-------------------------------
504
(Feel free to propose or add new sections here about what we should do to
505
get bzr into other places.)
507
For the currently-under-development release of Ubuntu, no special action
508
is needed: the release should be picked by Debian and synced from there into
511
Releases off stable bzr branches should go in to the ``-updates`` of the
512
Ubuntu release that originally contained that branch. (Ubuntu Lucid had
513
bzr 2.2.0, so should get every 2.2.x update.) This means going through
514
the `SRU (Stable Release Updates)
515
<https://wiki.ubuntu.com/StableReleaseUpdates>`__ process.
517
As of September 2010, bzr has applied to the technical board to be added
518
to the `MicroReleaseExceptions
519
<https://wiki.ubuntu.com/StableReleaseUpdates/MicroReleaseExceptions>`__
520
category so that whole bugfix releases can more easily be approved.
522
**After making a bzr stable-release release, nominate the most serious bug
523
for the appropriate Ubuntu release and subscribe the `ubuntu-sru` team.**
525
This requires a couple of tricks (please reconsider and tweak as things
526
evolves from one release to the other):
528
* create a distro task with the ``Also affects distribution`` button and
529
select ``bzr (Ubuntu)``.
531
* change the *URL* to point to ``ubuntu/+source/bzr`` instead of ``bzr``
532
(this is needed if you create the distro task but not if it exists
533
already). You should now be able to click the ``Nominate for release``
534
button and select the right Ubuntu release. As of September 2010, this
537
* ``maverick`` for the 2.2 series,
538
* ``lucid`` for the 2.1 series,
539
* ``karmic`` for the 2.0 series.
541
* Subscribe the ``~ubuntu-sru`` team to the bug.
543
* Add a comment targeted to ``~ubuntu-sru`` explaining the expectations
544
(we are targeting running the test suite during the build which, as of
545
September 2010, fails for known reasons that are currently addressed).
546
Search for bugs tagged with ``sru`` for examples and don't forget to tag
547
the bug you selected.
