The bot was acting, so I checked WTF was going on... and what do you know... new patch.
Copy paste from http://www.hiveworkshop.com/
Despite Blizzard's patch notes not mentioning it, we have confirmation that the 8mb multiplayer limit for maps has been removed on Battle.net! Various Hive Workshop users have tested out maps over 8mb, including a specialized version Gaias Retalliation ORPG which is around 50mb. Map maker @Zwiebelchen succeeded to host and play that map online in Battle.net. Other map makers and testers reported the same.
What does this mean? This means one of the biggest limits of WC3 modding has been taken off. There is so much more map makers and other types of modders can do now! This makes room for more creativity and higher quality content, along with more things to experience and improve in custom games online. The top RPGs can finally be expanded and epic strategy maps can now have more room for upping the quality without sacrificing quantity. Horror, first person shooter, anime, Sci-Fi, and more types of maps can be taken to a whole another level. We can also see more hi-res imports from models, textures, etc.
There are also some World Editor and file changes (including bug fixes) reported by some users, and you can discuss some of the specifics in this thread or throughout the Patch Discussion forum. We'll hope to have some sort of list of the changes and bug fixes.
Here you can find our thread from may regarding our meeting with Blizzard about The Future of Warcraft. You can find the PDF document Blizzard seems to be following attached to the bottom of the mini-article's first post.
