Feature Freeze #

Announce a feature freeze #

(Skip for patch releases) Usually, a feature freeze for one week is announced in #minetest-dev. New features aren’t accepted in this time and people focus on finding and fixing bugs. To find high priority issues faster, consider linking a release candidate binary to get more test results. This release candidate is usually also posted on the forums (News section).

The feature freeze and release date is set by core developers.

Autogenerate files #

Also update the translation templates:

  • Engine: Regenerate Gettext files with util/updatepo.sh. Note that before that, you most likely want to import existing changes first.
  • Builtin: Change directory to builtin, then run util/mod_translation_updater.py from there

Also ensure that the language setting enum values contains en: there is no “en” directory, but Luanti supports it.

Read Translation for details.

Update source strings on Weblate #

Make sure that the source strings on hosted.weblate.org are up-to-date.

Do not just blindly run the scripts without checking. Check if the source strings on Weblate were actually updated. A simple way to check is to look at any translation that was at 100% (on Weblate) before the update. After the update, the percentage should drop because of new strings. If it didn’t drop but you know there are new strings in Luanti, this means the update failed.

Before releasing #

Verify special translation strings #

The translation files contain a special string: LANG_CODE (see Translating).

Verify that all *.po files have a valid value for these strings because translators frequently misunderstand them and enter an invalid value. Fix any invalid values on Weblate by either entering the correct one or by removing the bad translation.

Update translations from Weblate #

How to do this -> Translating#How_to_merge_translations_from_Hosted_Weblate

If doing a backported release, you can use the following command to cherry-pick all translation commits from weblate:

git log --reverse --pretty=format:"%h" $BASE..weblate/master -- po | xargs -L1 git cherry-pick

BASE is the commit on master to start from when looking for translation commits. This commit should be newer than the last translation commit on the backport-X branch.

Update main menu credits #

This consists of:

  • Making use of util/gather_git_credits.py
    • edit the REVS_ACTIVE variable to contain the version number of two major versions in the past (e.g. 5.6.0 if you are releasing 5.8.0)
    • run the script
  • Editing builtin/mainmenu/credits.json and putting the results there
  • Don’t forget to update the list of core developers if that changed

Update website credits #

Once the credits are decided on in the previous step, update the website to be in sync with the mainmenu. Simply copy the same credits.json to here: https://github.com/minetest/minetest.github.io/tree/master/_data

Update changelog #

Changelog can be found here.

Ensure protocol version codes have been bumped #

If not a patch release: ensure that PROTOCOL_VERSION has been increased since the last release. (deciding discussion)

If formspec features have been added: ensure LATEST_FORMSPEC_VERSION has been increased since the last release.

The process #

This is mostly done by several core developers.

Update version in source #

The process with patch releases is slightly different but the script will take care of it correctly in any case.

  • Define a new version number by running util/bump_version.sh. Verify that this script correctly:
    • changes TRUE to FALSE for the line set(DEVELOPMENT_BUILD TRUE) in CMakeLists.txt
    • updates the version number and release date in misc/net.minetest.minetest.appdata.xml
    • and commits.
  • Tag the version in local git (the script does this) to allow the CMake versioning script to remove the git hash from the version. Do not push the tag to GitHub yet.
  • Build, get newest minetest_game, run and check if the thing seems to be working.

Build Windows version #

As of December 2023, we use the mingw artifacts of the “windows” CI workflow.

  • Extract the outer ZIP file so that users only have one ZIP file to extract (should be named luanti-5.x.x-win64.zip)

Note that the correct build only shows up after the release commit has been pushed to Github.

→ → → Make sure that the Windows builds work before continuing to do anything ← ← ←

Mini checklist of things to test #

Note: Don’t cheat on this by testing in Wine, it has happened that things crash/break in wine while they are fine on real Windows.

  • check that the build identifies itself as 5.x.x not 5.x.x-dev or 5.x.x-abc4de7
  • click some menu buttons
  • create world with MTG, enter it, exit back to menu
  • open multiplayer tab, attempt to join a server
  • install a package from CDB, uninstall it again
  • enable dynamic shadows, join in-game and look

Upload packages to somewhere #

  • All official builds are hosted at Github: https://github.com/minetest/minetest/releases
  • The Windows build is created by CI
    • (see above)
  • The macOS build is created by Github Actions
    • you will only be able to grab the build after the release has been pushed
    • download the artifact, unpack it once, you should have a luanti-5.x.x-osx.zip. This is then uploaded.
  • Android APKs are also uploaded here when they’re done
    • these are signed before uploading, see a few sections below

Update branches and tags of minetest on GitHub #

Tagging is handled by the script for the engine.

The new release should be merged to the stable-5 branch on both minetest. Its important to merge, and not just rebase, so that git describe works.

The problem on the stable-5 branch #

Usually, merging releases onto the stable branch just consists of adding the commits to the branch, as it contains direct ancestors of master commits, and git can do a fast forward. During release/freeze of 5.0.1 (both minetest and minetest_game), the ancestor rule has been broken.

Therefore, you’ll generate merge commits, but this shouldn’t be a problem. In the case of merge conflicts, ensure that the changes on stable-5 are all discarded in favor of the tagged commit at master, by doing a merge commit like:

   git checkout version-tag
   git merge -s ours origin/stable-5
   git push origin HEAD:stable-5

Tag Android deps #

Create a new tag on this repo with the version number of the release. This is to make it easier to figure out which state an APK was built from.

Update Launchpad stable build to get Ubuntu builds for the new version #

celeron55, rubenwardy, and ShadowNinja have access.

Process:

  • Go to minetest-c55/upstream and minetest-c55/upstream_game and click “start import”.
  • First, find out the commit hashes of the minetest and minetest_game git repos corresponding to the release.
  • Now visit the recipe.
  • At the bottom of the page there is a section called “Recipe contents”. In this section you need to edit the recipe. Make sure you update:
    • The version number at the end of the first line. Doing this is a must otherwise there would be duplicate packages which would lead to a fail. The version number has a format like 5.1.1-ppa0. You should keep the ppa postfix so that it’s easy to differentiate the package by origin, ppa or upstream Debian.
    • The commit hash of the main minetest repo in the second line.
  • Check whether everything has been updated correctly.
  • Click the green “Request builds” link, enable the newer distro versions, and click confirm.

The build has two steps: first it assembles the source code and uploads it, then it builds the code. If the first step completed successfully but the second one failed, you need to update the version number in the recipe (e.g. 1.2.3-ppa1) before rebuilding.

Build and publish Android APK #

nerzhul or rubenwardy have access to Google Play. Both also hold the signature keys for the app.

Signing APKs for the Play Store #

  • Wait for CI to finish
  • Download the .aab from GitHub CI
  • Sign: Android/Sdk/build-tools/34.0.0/apksigner sign --ks ~/Documents/keystore-minetest.jks --min-sdk-version 21 ~/Downloads/app-release.aab
  • Upload to Google Play

Creating Native Debug Symbols #

FIXME: nobody does this anymore. what now?

  • Copy native/build/intermediates/ndkBuild/release/obj/local/ to new folder
  • Remove all but .so files from new folder
  • Check the .so contain debug info using the file command
  • zip -r symbols.zip .

After releasing #

Reenable -dev version suffix #

(Skip for patch releases) Check that the util/bump_version.sh script did the following steps:

  • Update the version number in CMakeLists.txt and the titles of doc/client_lua_api.txt and doc/menu_lua_api.txt
  • Change FALSE to TRUE for the line set(DEVELOPMENT_BUILD FALSE) in CMakeLists.txt. This will add the -dev suffix to the version name again.
  • Commit.

Write a release notice #

  • Don’t forget to edit the luanti.org page (Repo).
    • currently you will need to update machine readable metadata in _data/release.yml and downloads.html itself.
  • Post a new topic in the News section of the forum. See Changelog.
    • It is customary to sticky the newest release topic and lock older ones.
  • Add a new post to the blog
  • Announce the release on Twitter and Mastodon. rubenwardy has access.

Update wiki version template #

There is a special wiki template containing the version number at [1], used to make updating various wiki pages by hand less tedious. Update it so it includes the latest version.

Notify known package maintainers #

  • Arch Linux/Manjaro: can be flagged outdated on the package page
  • Debian/Ubuntu: has own version tracking, no need to contact
  • Fedora and others: should automatically show up here, but can be flagged manually
  • F-Droid: has volunteer maintainers, if nobody notices consider opening an issue here
  • Snap: open an issue (or contribute) here
  • Flatpak: open an issue (or contribute) here
  • Gentoo: has own version tracking, no need to contact

You can find out how quick various distro are to adopt new versions by visiting Repology.

ContentDB #

Add a new version #

Add the new version to the drop-down list of compatible Luanti versions that authors can select for their things.

Note that CDB tells Luanti versions apart by their protocol version so this is obviously not applicable to patch releases.

People who have access: rubenwardy + ???

Package devtest #

Minetest Game is no longer connected to our release cycle, so we can ignore it.

The Development Test package needs to be released manually. Make a new release, upload a ZIP file with Development Test as it looks like the Luanti source tree in the stable branch, and set the minimum and maximum Luanti versions to the exact Luanti version it is intended for.
