=== Configuration changes for system administrators in 1.34 ===
==== New configuration ====
-* …
+* $wgAllowExternalReqID (T201409) - This configuration setting controls whether
+ Mediawiki accepts the request ID set by the incoming request via the
+ `X-Request-Id` header. If set to `true`, that value will be used throughout
+ the code as the request identificator. Otherwise, the sent header will be
+ ignored and the request ID will either be taken from Apache's mod_unique
+ module or will be generated by Mediawiki itself (depending on the set-up).
==== Changed configuration ====
+* $wgUseCdn, $wgCdnServers, $wgCdnServersNoPurge, and $wgCdnMaxAge – These four
+ CDN-related config variables have been renamed from being specific to Squid –
+ they were previously $wgUseSquid, $wgSquidServers, $wgSquidServersNoPurge, and
+ $wgSquidMaxage respectively. This aligns them with the related existing
+ variable $wgCdnMaxageLagged. The previous configuration variable names are
+ deprecated, but will be used as the fall back if they are still set.
+ Note that wgSquidPurgeUseHostHeader has not been renamed, as it is deprecated.

==== Removed configuration ====
-* …
+* $wgWikiDiff2MovedParagraphDetectionCutoff — If you still want a custom change
