16 Some specific notes for MediaWiki 1.38 upgrades are below:
19 For notes on 1.36.x and older releases, see HISTORY.
21 === Configuration changes for system administrators in 1.38 ===
24 ==== New configuration ====
25 * $wgBrowserFormatDetection – This setting allows overriding browsers' automatic
26 detection and handling of formats. It's initially used to prevent auto-linking
27 of possible telephone numbers in wiki pages' output in Safari on iOS; this can
28 be re-enabled if you wish, or locally extended for other browsers' quirks.
31 ==== Changed configuration ====
32 * $wgMaxImageArea - This setting may now be set to false to disable size
33 checking before scaling. Extensions can still override its value by
34 using the BitmapHandlerCheckImageArea hook.
37 ==== Removed configuration ====
38 * $wgShellLocale - This setting has been removed as it was a flawed solution
39 to the problem of locale dependence, MediaWiki will now always set a locale
40 of C.UTF-8 or C and works around the remaining problems of the C locale by
41 not using escapeshellarg. This follows the direction of PHP 8.0, which sets
42 a locale of C by default instead of respecting LC_CTYPE.
43 * $wgIncludejQueryMigrate - Deprecated in 1.36. We only support jQuery v3.
46 === New user-facing features in 1.38 ===
49 === New developer features in 1.38 ===
50 * Added a deleteUserEmail maintenance script - This file enables the deletion
51 of a given user's associated email address. It can be helpful for
52 privacy-preserving operations.
55 === External library changes in 1.38 ===
58 ==== New external libraries ====
