Time for a new release, just in time for the weekend:

- server: Add missing entitlement for iOS >= 17. Kudos to [@alexhude][] for
helping get to the bottom of this one.
- stalker: Improve exclusive store handling on arm and arm64. Instead of
potentially expanding the current block to include instructions beyond where
the block would naturally end, we move to a safer approach: Once we encounter
an exclusive store, we look back at the previously generated blocks to see if
we can find one with an exclusive load. If we do, we mark this range of blocks
as using exclusive access. We also invalidate the blocks, so that problematic
instrumentation can be omitted upon recompilation. To also allow custom
transformers to adapt their generated code, we introduce
StalkerIterator.get_memory_access(). Thanks for the fun and productive
pair-programming, [@hsorbo][]!
- gumjs: Add *StalkerIterator.memoryAccess*, allowing a custom transformer to
determine what kind of instrumentation is safe to add without disturbing an
exclusive store operation. Set to either 'open', when “noisy” instrumentation
such as callouts are safe, or 'exclusive', when such instrumentation is risky
and may lead to infinite loops. (Due to an exclusive store failing, and every
subsequent retry also failing.)
- gumjs: Fix CModule bindings for Stalker on arm.
- stalker: Fix crash on invalidation in added slabs.
- arm64-writer: Add put_eor_reg_reg_reg(). Thanks for the fun and productive
pair-programming, [@hsorbo][]!
