The servers have been updated to be able to process the 5.2 combat log format. Existing reports that caused a "Miss type not supported" error should now work as expected.
The new tier 15 raid Throne of Thunder has been added with all bosses. Recognition & kill detection should work. Difficulty detection is not yet in place; player limits will depend on player counts and difficulty will always be reported as normal. We will add further detection and validation rules over the course of the week.
