== [[m:Special:MyLanguage/Tech/News/2017/31|Tech News: 2017-31]] ==

<section begin="technews-2017-W31"/><div class="plainlinks mw-content-ltr" lang="en" dir="ltr"><div class="plainlinks">
Latest '''[[m:Special:MyLanguage/Tech/News|tech news]]''' from the Wikimedia technical community. Please tell other users about these changes. Not all changes will affect you. [[m:Special:MyLanguage/Tech/News/2017/31|Translations]] are available.
 
'''Problems'''
*Some pages show the error <code>Lua error in mw.wikibase.entity.lua at line 34: The entity data must be a table obtained via mw.wikibase.getEntityObject</code>. This problem happens on pages with a [[:w:en: Lua (programming language)|Lua module]] that uses Wikidata. The developers are working on fixing the problem. You can fix a page by opening it for editing and then saving without changing anything. [https://phabricator.wikimedia.org/T170039]
*Wikidata and German Wikipedia could not be edited for an hour on 28 July. You can read why and how we could avoid it in the future in the [[wikitech:Incident documentation/20170728-s5 (WikiData and dewiki) read-only|incident report]].

'''Changes later this week'''
*Some wikis already have the larger and brighter [[mw:Contributors/Projects/Accessible_editing_buttons|OOjs UI edit page buttons]]. All remaining wikis except Commons will have these from 1 August. [https://phabricator.wikimedia.org/T162849]
* <span title="Recurrent item">[[File:Octicons-sync.svg|12px|link=]]</span> The [[mw:MediaWiki 1.30/wmf.12|new version]] of MediaWiki will be on test wikis and MediaWiki.org from 1 August. It will be on non-Wikipedia wikis and some Wikipedias from 2 August. It will be on all wikis from 3 August ([[mw:MediaWiki 1.30/Roadmap|calendar]]).

'''Meetings'''
* <span title="Recurrent item">[[File:Octicons-sync.svg|12px|link=]]</span> You can join the next meeting with the Editing team. During the meeting, you can tell developers which bugs you think are the most important. The meeting will be on [http://www.timeanddate.com/worldclock/fixedtime.html?hour=19&min=00&sec=0&day=01&month=08&year=2017 1 August at 19:00 (UTC)]. See [[mw:Editing team/Weekly triage meetings|how to join]].

'''Future changes'''
* The default font in the edit window will soon change for some users. Instead of using the browser default it will be monospace. Users can change this in their preferences. This should only change this for some users on Macs and iOS devices. [https://phabricator.wikimedia.org/T171201]
