- Looking for Diablo 3 Console patches?
A patch is an update to a computer program that fixes bugs, makes changes, and adds content. Most computer games are patched regularly, to fix problems, adjust game balance issues, and sometimes add content. Patches are designated by version numbers; v1.01, v1.02a, v1.2b, etc.
Patches are usually embraced by players, as they bring desired bug fixes and can shake up the game with rebalances, added items, and more. Opinions always differ though, since while everyone likes improvements and buffs to their character, cries of "nerfed!" always ring out, as various overpowered skills, items, monsters, and other things are reduced in value or power, much to the chagrin of players who had come to count on those imbalances working to their favor.
 Diablo 3 Patches and Hotfixes
Patches are released by Blizzard to fix bugs and remedy issues with game balance and gameplay issues. Most patches are minor with just a few bug fixes and game tweaks. Some patches are major content updates with dozens of important game changes or even new features, such as the PvP Battle Arena.
Hotfixes are small, urgent changes that are fixed directly to the servers, without requiring a full patch. A number of skills that the developers felt were overpowered were nerfed via hotfixes, shortly after Diablo III's release.

 What to Expect in Diablo 3 Patches
The Diablo III developers will support their game with regular big fixes and other patches; this is standard for Blizzard games, since the company has a legacy of providing excellent long term game support. The D3 Team is not planning to include a great deal of new content in the patches though, since they want to save it up and make major updates in expansion packs. Jay Wilson spoke on their philosophy in an interview from Blizzcon 2010.
When asked in January 2012 on Twitter by @Procrastajason, "Is the retail release of the game the entirety of the content we'll see for a while or will there be content patches ala WoW?" Blizzard reiterated
 Diablo III Beta Patches
Blizzard patched the beta client 18 times, making changes both large and small. All these patches came with lists of feature changes, and many more details about them were uncovered by data mining. See the Diablo 3 Beta patches article for more details, or click on the individual patch pages.
 Diablo 2 Patches
There were numerous patches issues to Diablo II. The game is up to v1.13c, with the most recent patch released in May 2010. Blizzard has not released a patch since then.
Diablo II has released more content and major changes via patches than is common for computer games; especially ones that have been on the market for years and years. Several of Diablo II's patches, most notably v1.10, introduced a great deal of new content and brought about sweeping changes in the balance of the skills, characters, monsters, and more.
