Earlier today Apple introduced this year's roundup of new iStuff but I thought this simultaneous press release was interesting: https://security.apple.com/blog/memory-integrity-enforcement/
Today we’re introducing the culmination of this effort: Memory Integrity Enforcement (MIE), our comprehensive memory safety defense for Apple platforms. Memory Integrity Enforcement is built on the robust foundation provided by our secure memory allocators, coupled with Enhanced Memory Tagging Extension (EMTE) in synchronous mode, and supported by extensive Tag Confidentiality Enforcement policies.

With the introduction of the iPhone 17 lineup and iPhone Air, we’re excited to deliver Memory Integrity Enforcement: the industry’s first ever, comprehensive, always-on memory-safety protection covering key attack surfaces...
I think we know who's had "always-on memory-safety protection covering key attack surfaces" for awhile now <ahem> but of course Apple will probably be hailed as groundbreaking by the industry. Just thought this was interesting and tangentially relevant to GrapheneOS.
