=== Configuration changes in 1.28 ===
+* BREAKING CHANGE: $wgHTTPProxy is now *required* for all external requests
+ made by MediaWiki via a proxy. Relying on the http_proxy environment
+ variable is no longer supported.
* The load.php entry point now enforces the existing policy of not allowing
access to session data, which includes the session user and the session
user's language. If such access is attempted, an exception will be thrown.
* $wgForeignUploadTargets now defaults to `[ 'local' ]`, where `'local'`
signifies local uploads. A value of `[]` (empty array) now means that
no upload targets are allowed, effectively disabling the upload dialog.
+* The deprecated $wgEditEncoding variable has been removed; it was only used
+ for Esperanto language character conversion. You are now recommended to use
+ input methods provided by the UniversalLanguageSelector extension.
+* When $wgPingback is true, MediaWiki will periodically ping
+ https://www.mediawiki.org/beacon with basic information about the local
+ MediaWiki installation. This data includes, for example, the type of system,
+ PHP version, and chosen database backend. This behavior is off by default.
