Cocos Creator v2.1.2 released!
Six months has passed since the release of Cocos Creator v2.1.0, and the team has been hard at work creating the next releases. Cocos Creator v2.1.0 is our most popular release to date. The development teams effort will be spent on Cocos Creator v2.1.0 and therefore maintenance of v2.0.x will be discontinued. v2.0.x users should consider upgrading to v2.1.1 when it makes sense to do so.
The v2.1.2 update includes not only general experience optimizations and bug fixes, but also the optimization of pure 2D projects, as well as a decrease in project size. At the same time, this version also incorporates all the changes in v2.0.10, supporting the two new platforms: Xiaomi Mini Games and Cocos Play.
What’s New
Optimizing 2D projects
Previously we had always positioned v2.1 as a 3D predecessor, so v2.1 was lagging behind for the care of pure 2D projects. However, v2.1.2 has been carefully optimized to work well with both 2D and 3D projects. Now we officially recommend that all v2.0 projects be upgraded to v2.1.2. Projects upgraded from v2.0 will default to 3D modules, ensuring that there is no impact on the package and performance of 2D projects. To add 3D support, manually check the 3D module in Menu → Project → Project Settings → Module Settings.

Improvements
Improve the WeChat game resource loading process
-
Fixed a problem where the resource might not load successfully (thanks to snow_storm for feedback) [#97]
-
Optimize processing logic when caching fails [#98]
-
Fixed a problem with subsequent callbacks of remote images without multiple callbacks [#96]
-
Avoid crashes caused by oversized json file parsing (thanks to canghai7789 for feedback)[#101]
-
Adjust the cache interval to reduce the impact on the game frame rate [#97]
Editor improvements
-
Complete automatic atlas algorithm, now you can generate the smallest size atlas without manually adjusting max size
-
Improve Windows platform support for multiple monitors. Now the editor automatically detects window visibility when it starts, ensuring that the window displays properly.
-
Increase warning information before project upgrade or downgrade to prevent users from misoperation
-
Added DragonBones and Spine’s dressup demo [#725] in the included sample project
-
Optimized editor compatibility with GPU devices and reduced false positives due to WebGL compatibility
-
Improved the Asset Watcher mechanism. If the type of an accessor(getset) of a component is defined as an array of resources, the setter will be triggered to reset the entire array when the corresponding resource changes.
Engine improvements
-
Turn off preserveDrawingBuffer by default on WeChat game, which solves the problem that the game will be stuck for a few seconds from the background to the front desk [#4537]. (The WeChat game must be enabled with preserveDrawingBuffer when it is first released, otherwise the scene switch will be black)
-
Improved positioning accuracy of Label on native platform [#4765], [#1764]
-
Optimized BMFont Memory usage during rendering [#4651]
-
Allow Label to be modified again after setting it to BITMAP mode (although it is still not recommended, resulting in additional memory and performance overhead)
-
Reduced the timeout for loading ttf fonts from Web platform from 60s to 3s [#4536]
-
Added
urlattribute to Asset to get the actual url of the current resource. Developers can directly call the platform’s native API to use these urls [#4536]

Since v2.0.0 has been rewritten from the bottom with a 3D renderer, Cocos Creator has evolved into a game engine that can be both lossless and purely 2D and 3D. In the future, Cocos Creator will continue to adhere to the 2D first concept, continue to improve 2D game development experience and basic performance, and gradually introduce 3D features suitable for 2D games.
We are proud of v2.1.2, and we wonder if you are proud too? Good quality is inseparable from careful polishing, and Cocos will continue to improve the quality of its products with a down-to-earth spirit. We welcome our community to continue to submit feedback to us through forums, GitHub, Cocos Enterprise Services and other channels!
