Last week's Operation Developer Love was a little disappointing as it contained no updates. At least it meant that there was nothing bad happening under the hood on Facebook and no major changes that developers needed to worry about. That all changes this week with Facebook announcing one major update to the platform.
To that end, the company says that applying patches to the FB object will no longer work. You also can no longer directly manipulate properties like FB._https. Some developers rely on accessing those internal properties to make apps work though, but Facebook wants you to stop. They even compiled a handy list of publicly available methods that developers can instead use. Of course, you can still use methods that aren't part of the public API, but Facebook says that those methods can be changed or removed without notice.
As for the bug report, there were 174 bugs reported with 48 of them being fixed. Twenty-seven bugs were reproducible and accepted so they should be fixed by next week.
