Recent parser change regarding tildes in comments?
by Thomas Dalton 28 Feb '26

28 Feb '26

Has the parser just been changed with regards to tildes (~~~~) inside HTML comments? It appears they used to be ignored, and are now suddenly being replaced en masse the next time someone edits the page (and can't be easily reverted - it just changes the sig to the reverter's instead). See http://en.wikipedia.org/wiki/Wikipedia:Articles_for_creation/2006-06-02-ear… for an example.

Hello, While I develop and design websites, I’m not a Mediawiki developer. A friend/client has been needing their site updated to the latest version, for several months. The site is currently running an outdated version and is needing an update/upgrade. If you have an interest in discussing this project, please contact me. Thank you, sincerely, M. Mead mmeadpond(a)icloud.com

Some of the referenced Phabricator tasks above _may_ still be private. Unfortunately, when security issues are reported, sometimes sensitive information is exposed and since Phabricator is historical, we cannot make these tasks public without exposing this sensitive information. If you have any additional questions or concerns regarding this update, please feel free to contact security(a)wikimedia.org or file a security task within Phabricator [3].

Extension:Layers
by Paul Vodrazka 06 Jan '26

06 Jan '26

Greetings, I hope everyone has had a great holiday season. I've been working on a new extension to allow for non-destructive image editing and annotation. Please help me fix issues and make improvements. I am leaning heavily on GitHub copilot so I would love to have some experts review my code and documentation. I am not nearly as qualified as most of the users here. There will be issues. Please be patient and kind. https://www.mediawiki.org/wiki/Extension:Layers https://github.com/slickdexic/Layers I look forward to some valuable feedback. Thank you, Paul Vodrazka
