+* When $wgEditSubmitButtonLabelPublish is true, MediaWiki will label the button
to store-to-database-and-show-to-others as "Publish page"/"Publish changes";
if false, the default, they will be "Save page"/"Save changes".

=== New features in 1.28 ===
* User::isBot() method for checking if an account is a bot role account.
collation, you will need to run the updateCollation.php maintenance script.
* Two new codes have been added to #time parser function: "xit" for days in current
month, and "xiz" for days passed in the year, both in Iranian calendar.
+* mw.Api has a new option, useUS, to use U+001F (Unit Separator) when
+ appropriate for sending multi-valued parameters. This defaults to true when
+ the mw.Api instance seems to be for the local wiki.
+* After a client performs an action which alters a database that has replica databases,
+ MediaWiki will wait for the replica databases to synchronize with the master database
+ while it renders the HTML output. However, if the output is a redirect to another wiki
+ on the wiki farm with a different domain, MediaWiki will instead alter the redirect
+ URL to include a ?cpPosTime parameter that triggers the database synchronization when
+ the URL is followed by the client. The same-domain case uses a new cpPosTime cookie.
=== External library changes in 1.28 ===
action=createaccount, action=linkaccount, and action=changeauthenticationdata
in the query string is now deprecated and outputs a warning. They should be
submitted in the POST body instead.
+* (T141960) Multi-valued parameters may now be separated using U+001F (Unit Separator)
+ instead of the pipe character. This will be useful if some of the multiple
+ values need to contain pipes, e.g. for action=options.
+* The API will now warn if input is not NFC-normalized Unicode or if it
+ contains invalid characters.
+* The 'normalized' list output by action=query and other modules that use
+ ApiPageSet may contain entries where the 'from' value is percent-encoded as
+ the raw value cannot be represented in a valid API response. These are
+ indicated by a 'fromencoded' boolean alongside the existing 'from' parameter.
+* (T28680) action=paraminfo can now return info about all submodules of a
+ module without listing them all explicitly.
=== Action API internal changes in 1.28 ===
* Added a new hook, 'ApiMakeParserOptions', to allow extensions to better
interact with ApiParse and ApiExpandTemplates.
