Most of the changes are backend code and database updates (partly to just update very old code, and partly to make some features due later in the year possible) - there will be very little visible change on Sunday.

One effect that may become apparent is install count adjustments - the current system just adds one (or takes one) from an existing stored number (similar to how post counts work). Over time this means errors have crept in and some counts are no longer exactly correct. Every install is also kept as a record in a database and after the update, when you mark a mod as installed (or uninstalled) it will actually work out the correct count from the database - this will mean counts (esp for older mods) may change slightly as they get corrected.
