=== Configuration changes in 1.29 ===
+* Default cookie expiration time has been reduced to 30 days. Login cookie expiration time is
+ kept at 180 days.
+* A new configuration variable has been added: $wgCookieSetOnAutoblock. This
+ determines whether to set a cookie when a user is autoblocked. Doing so means
+ that a blocked user, even after logging out and moving to a new IP address,
+ will still be blocked.
=== New features in 1.29 ===
+* (T5233) A cookie can now be set when a user is autoblocked, to track that user if
+ they move to a new IP address. This is disabled by default.
=== External library changes in 1.29 ===
