Feature wise difference between h265 and h266

Hi All,

I am totally new to this forum. So please pardon, if there is any mistake.

I have read that h266 uses several advanced algorithms and provides almost 50% more reduction than h265.
Other than the algorithms, I would like to know about any special features where h266 has an edge. (i.e. supported by h266, but not supported by h265).

Example: My understanding is that h266 supports AI based encoding, but h265 does not support it. In similar way, I would like to know about any new features in h266.
Could anyone please help me on this??
