EDIT: when this article was originally written, the 2.1.2 plugin SDK was not available, which caused a lot of confusion. The new SDK is now posted, and the building instructions are completely updated.
Beta 11 is out and this hopefully has the final set of SDK changes for 64-bit plugins. Besides a bunch of other fixes (see the release notes), here's the rough state of plugins:
- 32-bit plugins should just work. If you have a plugin that worked in X-Plane 10.11 but is broken in 10.20, please report a bug - even if it's not your own plugin! I really want to hear about any of these cases.
- 64-bit plugins should just work; if they don't, it may be due to programmer error, so please only report a 64-bit plugin problem if you wrote the plugin.
- A new SDK (2.1.2) is cut with real frameworks for the Mac; Sandy and I spent a pile of time working on this, but I need to update the wiki instructions. Docs coming in the next 48 hours I hope.
- Name and shame is gone for linking, so the logs should be clean. If your plugin crashes, you still get named and shamed.
