If your wiki uses markup like <div class="mw-content-ltr"> or <div class="mw-content-rtl"> without the required dir attribute, then these will no longer work in 2 weeks. There is a short-term fix that can be added to your local wiki's Common.css page, which is explained at T287701. From now on, all usages should include the full attributes, for example: <div class="mw-content-ltr" dir="ltr" lang="en"> or <div class="mw-content-rtl" dir="rtl" lang="he">. This also applies to some other HTML tags, such as span or code. You can find existing examples on your wiki that need to be updated, using the instructions at T287701.
Last week, all wikis had slow access or no access for 30 minutes. There was a problem with generating dynamic lists of articles on the Russian Wikinews, due to the bulk import of 200,000+ new articles over 3 days, which led to database problems. The problematic feature has been disabled on that wiki and developers are discussing if it can be fixed properly.
