Happy belated Summer Solstice to all who celebrate. This is a maintenance release that includes all of the merged PRs through July 2025 (last year).
Note
As you may have noticed, highlight.js has been inactive since last summer, through no one's fault; maintaining open source projects is time-consuming. I'll be doing my best to keep the lights on around here, but I'll need the community's help. If you are interested in helping review pull requests, contributing, or even becoming a maintainer, speak up in #1678.
Important
Why is this version not published on npm or CDNs?
In December 2025, npm revoked all classic tokens for improved security. Since we haven't had a release since July 2025, I didn't notice that our release pipeline is currently broken because it uses a now-revoked token.
When will 11.11.2 be available on npm and/or CDNs?
This week. I need to update our Release pipeline to use npm's Trusted Publisher functionality.
I see two 11.11.2 releases on my GitHub feed, were you hacked?
A 11.11.2 tag was created prematurely on GitHub and caused a run failure during the release pipeline since all work to bump the release had not been completed. There was no version 11.11.2 that was accidentally published to npm or the CDNs; therefore, the Git tag has been recreated to point to f273f00.
