What happened to AIX?

So, what exactly transpired with AIX? I've been hearing some buzz about its recent developments, but I'm not entirely clear on the specifics. Did it experience a significant price swing? Was there a security breach or a hack? Or perhaps there was a major update or partnership announcement that's got everyone talking? Whatever the case may be, I'd love to get a concise yet informative overview of what's been going on with AIX lately.
