Cuberite Newsletter Summer 2020

Hello all Cuberite fans - it’s been about 6 months since the last update, so it’s about time to let you know the current status of the project as well as what’s gone on since the last update!

General News

  • In general, the Cuberite infrastructure has had a bit of an overhaul. A new dedicated server has been commissioned and most services rebuilt to run as docker containers on this new server. Hopefully this should lead to more uptime and a lower operating cost.
  • As part of the infrastructure upgrade, the build server has been replaced. Production builds now use a version-controlled container for consistency and to make upgrades easier. As a result, old updater scripts or versions of the Cuberite app that did not use Cuberite’s canonical download URIs will no longer work.
  • Binary builds for Mac are now once again being produced and are available for download fom the website. FreeBSD builds remain unavailable due to a lack of build slaves.
  • Before the new server could be activated, the old email system for the forum failed. If you didn’t get notifications for this period, don’t worry as the problem has now been resolved.
  • As part of the upgrade to the new system, emails from the forum are now sent from rather than as before.
  • Public demo servers are now available and you can connect on or depending on your preferred location. Server contents are regularly reset and uptime is not guaranteed. Please see the website for more information.
  • Progress for protocol versions greater than 1.12 is encouraging, and Cuberite now accepts connections from 1.13 clients, although the fundamental changes required for implementing all the new features are still incomplete, as yet.

Development News

  • Cuberite has updated to C++17, allowing use of the new language and standard library features in the project. As a result, the minimum compiler versions are now clang 6 and GCC 7.
  • The CMake system has also been reworked, so a newer version of CMake is required. CMake 3.13 is required, but 3.17+ is advised to take advantage of LTO and unity builds.
  • Since the last update, development effort has been coming on slowly but surely, with 174 PRs merged since the last update. The changes include:
