Guia

Releases and development of QGIS follow a timebased schedule.

  • Os números pares da versão (2.18, 3.2 etc) são versões de lançamento.
  • Os números ímpares da versão (2.99, 3.1 etc) são versões de desenvolvimento.

A new release will happen every four months. In the first three months, new development is taking place. In the last month before a release, a feature freeze is invoked and the final month is used for testing, bugfixing, translation and release preparations. When the release happens, a branch with an even release number is created and the master branch advances to the next odd version. After the release a call for packaging is issued.

A cada terceiro lançamento (a começar com o 2.8) é um lançamento de longo prazo (LTR) que é mantido até ocorrer o próximo lançamento de período longo.

Fase de desenvolvimento

In the development phase, developers work on adding new features for the next release. Early adopters can use the nightly builds we have for all major platforms to see the development progress, do preliminary testing and provide bug reports and their thoughts to help with development.

Congelamento de funcionalidade

In the feature freeze phase, new features are not allowed in anymore and the focus of everyone moves from enhancing QGIS to stabilizing it. This also turns the nightly builds effectively into prereleases.

Utilizadores devem começar a fazer testes intensivos destes pré-lançamentos no seu ambiente para verificar se não existe problemas, eles não querem ver o lançamento que vai sair. Todos os problemas devem ser reportados (veja `Erros, Características e Problemas`_). Tudo que não é noticiado, irá acabar no próximo lançamento. Apenas em casos de sérios problemas ocorrerá um lançamento pontual (ex.: 2.4.1). Portanto o teste dos pré-lançamentos é o aviso de problemas é muito importante.

In the feature freeze, developers monitor the bugtracker and start working on fixing the reported issues and update the visual changelog with the features they added.

With the start of the feature freeze, the translation files will be updated so that translators can start their work. Note that this might be an incremental process as although the features are frozen, bug fixes might still introduce translation string changes.

Two weeks before the release, a hard freeze is initiated after which only fixes to severe problems and regressions introduced after the feature freeze are allowed in.

The release manager announces this on feature freeze.

Lançamento

On major and minor release dates, the release branch is created and the release is tagged and tar balls are prepared. Point releases are just tagged and tar balls are created.

The packagers are notified that packaging can begin.

Once some packages are available the release can be announced and the website is updated accordingly.

Calendário de lançamento

The schedule is aligned to produce roughly the same dates for each year given our four monthly releases with LTRs in late february.

Beginning after 2.12 the development phase is always 12 weeks and the freeze phase is at least 5 weeks. Remainders are used to extend the freeze phase of LTR releases.

Point releases will happen every month on the latest release branch and the LTR branch, if there are backports.

In the first four months after its release, a new LTR is also the current LR. In this phase, the new LTR doesn’t replace the previous LTR in the LTR repositories. This happens as soon as a new LR is released.

This schedule is also available as «iCalendar».
