Od wersji 1.0, numerowanie wydań Django działa w ten sposób:
\nWersje są numerowane w formie A.B lub A.B.C.
A.B jest numerem wersji wydania funkcjonalnego. Każda wersja będzie przeważnie kompatybilna wstecz z poprzednim wydaniem. Wyjątki od tej reguły będą wypisane w informacjach o wydaniu.
C jest numerem wersji wydania łaty, który jest zwiększany przy wydaniach z naprawami błędów i bezpieczeństwa. Te wydania będą w stu procentach kompatybilne wstecz z poprzednim wydaniem łaty. Jedynym wyjątkiem jest sytuacja, gdy problem bezpieczeństwa lub utraty danych nie może zostać rozwiązany bez złamania kompatybilności wstecz. Jeśli tak się wydarzy, informacje o wydaniu będą zawierały szczegółowe instrukcje upgrade’u.
Przed nowym wydaniem funkcjonalnym, zrobimy alphę, betę i wydania „release candidate”. Są one w formie A.B alpha/beta/rc N, co oznacza N-tą alphę/betę/„release candidate” wersji A.B.
W gicie każde wydanie Django będzie miało tag określający jego numer wersji, podpisany kluczem wydań Django. Dodatkowo każda seria wydań ma swoją własną gałąź, nazwaną stable/A.B.x i wydania bezpieczeństwa lub bugfiksów będą tworzone z tych gałęzi.
For more information about how the Django project issues new releases for\nsecurity purposes, please see our security policies.
\nWydania funkcjonalne (A.B, A.B+1, itd.) będą wypuszczane średnio co osiem miesięcy – szczegóły w procesie wydawniczym. Te wydania będą zawierały nowe funkcjonalności, udoskonalenia istniejących funkcjonalności i tym podobne.
\nWydania łat (A.B.C, A.B.C+1, itp.) będą wypuszczane w miarę potrzeb, by naprawiać błędy i/lub problemy z bezpieczeństwem.
\nTe wydania będą w stu procentach kompatybilne z powiązanym wydaniem funkcjonalnym, o ile nie jest to niemożliwe z powodów bezpieczeństwa lub aby zapobiec utracie danych. Więc odpowiedzią na pytanie „czy powinienem upgrade’ować się do ostatniego wydania łaty?” zawsze będzie „tak”.
\nNiektóre wydania funkcjonalne będą oznaczone jako wydania „long-term support” (LTS). Te wydania będą otrzymywały poprawki bezpieczeństwa i utraty danych przez gwarantowany czas, zazwyczaj trzy lata.
\nNa stronie pobierania znajdziesz wydania, które zostały wyznaczone do „long-term support”.
\nStarting with Django 2.0, version numbers will use a loose form of semantic\nversioning such that each version following an LTS will\nbump to the next „dot zero” version. For example: 2.0, 2.1, 2.2 (LTS), 3.0,\n3.1, 3.2 (LTS), etc.
\nSemVer makes it easier to see at a glance how compatible releases are with each\nother. It also helps to anticipate when compatibility shims will be removed.\nIt’s not a pure form of SemVer as each feature release will continue to have a\nfew documented backwards incompatibilities where a deprecation path isn’t\npossible or not worth the cost. Also, deprecations started in an LTS release\n(X.2) will be dropped in a non-dot-zero release (Y.1) to accommodate our policy\nof keeping deprecation shims for at least two feature releases. Read on to the\nnext section for an example.
\nA feature release may deprecate certain features from previous releases. If a\nfeature is deprecated in feature release A.x, it will continue to work in all\nA.x versions (for all versions of x) but raise warnings. Deprecated features\nwill be removed in the B.0 release, or B.1 for features deprecated in the last\nA.x feature release to ensure deprecations are done over at least 2 feature\nreleases.
\nSo, for example, if we decided to start the deprecation of a function in\nDjango 4.2:
\nDjango 4.2 will contain a backwards-compatible replica of the function which\nwill raise a RemovedInDjango51Warning.
Django 5.0 (the version that follows 4.2) will still contain the\nbackwards-compatible replica.
Django 5.1 will remove the feature outright.
The warnings are silent by default. You can turn on display of these warnings\nwith the python -Wd option.
A more generic example:
\nX.0
X.1
X.2 LTS
Y.0: Drop deprecation shims added in X.0 and X.1.
Y.1: Drop deprecation shims added in X.2.
Y.2 LTS: No deprecation shims dropped (while Y.0 is no longer supported,\nthird-party apps need to maintain compatibility back to X.2 LTS to ease\nLTS to LTS upgrades).
Z.0: Drop deprecation shims added in Y.0 and Y.1.

\nAt any moment in time, Django’s developer team will support a set of releases\nto varying levels. See the supported versions section of the download\npage for the current state of support for each version.
\nThe current development branch main will get new features and bug fixes\nrequiring non-trivial refactoring.
Patches applied to the main branch must also be applied to the last feature\nrelease branch, to be released in the next patch release of that feature\nseries, when they fix critical problems:
\nSecurity issues.
Data loss bugs.
Crashing bugs.
Major functionality bugs in new features of the latest stable release.
Regressions from older versions of Django introduced in the current release\nseries.
The rule of thumb is that fixes will be backported to the last feature\nrelease for bugs that would have prevented a release in the first place\n(release blockers).
\nSecurity fixes and data loss bugs will be applied to the current main branch,\nthe last two feature release branches, and any other supported long-term\nsupport release branches.
Documentation fixes generally will be more freely backported to the last\nrelease branch. That’s because it’s highly advantageous to have the docs for\nthe last release be up-to-date and correct, and the risk of introducing\nregressions is much less of a concern.
As a concrete example, consider a moment in time halfway between the release of\nDjango 5.1 and 5.2. At this point in time:
\nFeatures will be added to the development main branch, to be released as\nDjango 5.2.
Critical bug fixes will be applied to the stable/5.1.x branch, and\nreleased as 5.1.1, 5.1.2, etc.
Security fixes and bug fixes for data loss issues will be applied to\nmain and to the stable/5.1.x, stable/5.0.x, and\nstable/4.2.x (LTS) branches. They will trigger the release of 5.1.1,\n5.0.5, 4.2.8, etc.
Documentation fixes will be applied to main, and, if easily backported, to\nthe latest stable branch, 5.1.x.
Django uses a time-based release schedule, with feature releases every eight\nmonths or so.
\nAfter each feature release, the release manager will publish a timeline for the\nnext feature release. The timeline for an upcoming feature release can be found\nin the corresponding wiki roadmap page, e.g.\nhttps://code.djangoproject.com/wiki/Version6.0Roadmap.
\nWork begins on the feature release A.B after the feature freeze of the\nprevious release, i.e. when the stable/A.B-1.x branch is forked.
You can find the current branch under active development in the\nDjango release process on Trac.
\nAll major and minor features, including deprecations and breaking changes, must\nbe merged by the feature freeze. Any features not done by this point will be\ndeferred to the next feature release.
\nAt this point, the stable/A.B.x branch will be forked from main.
After the alpha, all bug fixes merged in main are also backported to\nstable/A.B.x. Refactors are backported at the discretion of the merger.\nMergers will be more and more conservative with backports, to avoid introducing\nregressions.
In parallel to this phase, main can continue to receive new features, to be\nreleased in the A.B+1 cycle.
If there is still a consistent stream of release blockers coming in at the\nplanned release candidate date, a beta 2 will be released to encourage further\ntesting and the release candidate date will be pushed out ~1 month.
\nThe release candidate marks the string freeze, and it happens at least two\nweeks before the final release. Translators can then submit updated\ntranslations for inclusion in the final release. After this point, new\ntranslatable strings must not be added.
\nAfter the release candidate, only release blockers and documentation fixes are\nbackported.
\nIdeally, the final release will ship two weeks after the last release\ncandidate.
\nIf there are major bugs still being found 2 weeks after the release candidate,\nthere will be a decision on how to proceed (likely another release candidate\nwould be issued and the final release date will be pushed out).
\nAfter a feature release (e.g. A.B), the previous release will go into bugfix\nmode.
\nThe branch for the previous feature release (e.g. stable/A.B-1.x) will\ninclude bugfixes. Critical bugs fixed on main must also be fixed on the\nbugfix branch; this means that commits need to cleanly separate bug fixes from\nfeature additions. The developer who commits a fix to main will be\nresponsible for also applying the fix to the current bugfix branch.
