Coming not too long after the recent libtheora 1.2 beta release is now the official libtheora 1.2.0 milestone. This is a rather quick turnaround after the beta considering the prior libtheora 1.2 alpha had been worked on in 2018. Libtheora 1.1 was released in 2009 and since then there hasn't been any major stable updates.
The Theora 1.2 library update brings better ARM support, initial RISC OS support, various library changes, MinGW build fixes, performance improvements, and other code clean-ups/enhancements over the past many years.
