Weekly highlight

• Many Wikimedia tools were taken offline last week because of a security vulnerability in PHP. This affected many websites worldwide. Toolforge and Cloud VPS have been back up since October 22. Many important tools have been gradually restored. Some tools need the respective volunteer maintainers to restart them. Others still need to upgrade to a patched PHP version. Some tools were using older versions of PHP which are not supported by the recent security patches. They will require maintainers to upgrade to a more recent version. This might require additional effort. You can follow the work on Wikitech.

Updates for editors

• A new optional search experiment is running in the Wikipedia Android and iOS apps for Arabic, French, and Japanese Wikipedias. Participating readers can search inside articles and open quoted passages directly in their source articles, no answers or summaries are generated. This is the first of four experiments in Phase 2 of Semantic Search. It began on October 22 and runs for 20 days. Feedback is welcome on the project’s discussion page.
• The Future Audiences team is planning to bring Share Cards to Wikipedia on mobile. This feature gives users the option to share a visually appealing card with friends, based on the article they are reading. The card contains the article’s title, image, opening text, and related attribution, and links back to the article for full reading. Editors are invited to try out this feature by adding ?useformat=mobile&sharecard=1 to any article URL from October 29 to November 8. Share any thoughts on the project talk page and report any bugs on Phabricator.
• The default renderer for math formulas will change on November 2. After the change, the server sends the formula as MathML, and your browser uses MathJax to show it. This is the last step towards the Mathoid/RESTBase deprecation process, for sustainability and security reasons. You can ask questions or report problems. [1]
