MediaWiki 1.43 upgrade

MediaWiki 1.43.0 is the next long-term support (LTS) version of MediaWiki. It is expected to be released in December 2024.

MyWikis will begin to upgrade wikis to MediaWiki 1.43 soon after MediaWiki 1.43.0 is released by the Wikimedia Foundation. The process is expected to occur in stages, due to the amount of time needed to upgrade extensions.

This page serves as a central hub for information about MyWikis's upgrade to MediaWiki 1.43 for wikis on MyWikis Cloud, which include all wikis hosted under mywikis.wiki. Check back here for updates.

Upgrade eligibility criteria

Eligibility criteria will change to gradually include more and more wikis on MyWikis Cloud.

Currently, if your wiki is not automatically eligible, then your wiki may be eligible if all of the following criteria are met, pending a review by a member of our tech team:

• Criteria to be announced in the future

Eventually, all of these eligibility criteria will disappear, except for third-party community-developed extensions that remain incompatible with MediaWiki 1.43, which is outside of MyWikis's control.

Note: automatic eligibility does not mean the upgrade will happen automatically. It only means that no additional checks will need to be performed by our tech team.

How to request an upgrade

Before requesting an upgrade, please keep the following in mind:

• Please read the above eligibility criteria and confirm your wiki meets the criteria before making your request.
• Upgrades cannot be reversed. Once you upgrade to MediaWiki 1.43, you cannot downgrade back to MediaWiki 1.39.
• MyWikis is unable to assist with compatibility issues in extensions and third-party skins not maintained by MyWikis, the Wikimedia Foundation, or trusted partners.
• Some extensions and skins may have significantly differing functionality or appearances between their MediaWiki 1.43 and 1.39 versions. MyWikis is not responsible for fixing such issues.
• While we have performed extensive testing to make sure your 1.43 experience is flawless, MediaWiki 1.43 is a newly released MediaWiki version and every wiki is different. Please keep in mind there may still be some issues with using MediaWiki 1.43 at this time. Proceed with upgrading at your own risk.

If you understand the above stipulations, please visit mywikis.com/contact, log in to the Client Panel, and open a ticket with the subject line "MediaWiki 1.43 upgrade" and inform us of which wikis you'd like for us to upgrade to 1.43. We will then analyze your wiki to determine whether it's eligible for an upgrade at this time. If so, we'll upgrade you and let you know.

With limited exceptions, we cannot schedule upgrades for a specific time. If all goes well, the upgrade will take anytime between a few seconds to 5 minutes (yes, it's quick!) and will not have much impact on your wiki's uptime. Should something go wrong with your wiki's upgrade, we will restore from the latest backup and inform you that it failed.

Common questions

Will my wiki be automatically upgraded?

Many wiki owners would prefer to have finer-grained control over their wiki's version and the extension versions they use. Some wikis will be automatically upgraded. Wikis that do not currently meet our automatic eligibility criteria won't be automatically upgraded, but the upgrade process is very simple. See below answers for more details.

Is it possible to upgrade to MediaWiki 1.43 right now?

This depends on whether your wiki meets the above eligiblity criteria or not.

Over time, as we add support for more features, more wikis will become eligible for an upgrade to 1.43.

Is it possible to create a wiki on MediaWiki 1.43?

While the compatibility issues are still being resolved for MediaWiki 1.43, we will still create all new wikis on MediaWiki 1.39, but an option to immediately upgrade to 1.43 will be available for those who are interested. We will announce when this is possible.

Do I have to do any manual actions for the upgrade?

Other than requesting the upgrade, the vast majority of users will not need to perform any further actions. Our support team will reach out to you in case we need your assistance with processing your wiki's upgrade.

Is the upgrade free?

For all wikis already hosted under mywikis.wiki, the upgrade is free.

Why isn't the upgrade automatic?

MediaWiki (the wiki software used by Wikipedia, MyWikis, and many other wikis on the internet) is heavily customizable. Therefore, to ensure compatibility with everyone's wiki configuration settings, we will place the choice of using MediaWiki 1.43 or 1.39 in the hands of wiki owners until just before MediaWiki 1.39 is deprecated.

Does this upgrade impact my use of MyWikis Self Service?

It won't, because MyWikis Self Service supports both versions of MediaWiki.
