+
+=== Configuration changes for system administrators in 1.33 ===
+==== New configuration ====
+* $wgEnablePartialBlocks – This enables the Partial Blocks feature, which gives
+ accounts with block permissions the ability to block users, IPs, and IP ranges
+ from editing specific pages, while allowing them to edit the rest of the wiki.
+ It is a temporary setting for gradual enablement, current default to `false`,
+ and will be set to `true` and then removed once initial development completes.
+
+==== Changed configuration ====
+* $wgChangeTagsSchemaMigrationStage (T193868) — This temporary setting, added in
+ MediaWiki 1.32, now defaults to MIGRATION_NEW instead of MIGRATION_WRITE_BOTH.
+* $wgPasswordPolicy – There is a new password policy to check that the account's
+ password is not in the large blacklist. This is enabled by default for the
+ built-in user groups bureaucrat, sysop, interface-admin, and bot. To configure
+ this for other user groups, set the `PasswordNotInLargeBlacklist` flag `true`.
+* wgPasswordDefault – There is a new password type configuration using Argon2
+ password hashing (which requires PHP 7.2 and above). It's designed to resist
+ timing attacks, and (on systems with PHP 7.3+) GPU hacking; if you configure
+ argon2 to be used, by default, it will automatically choose the best available
+ algorithm depending on which version of PHP you have available. To use this,
+ you can set `$wgPasswordDefault = 'argon2';`.
