v0.5.0

Metal v0.5.0

Diff since v0.4.1

Metal.jl 0.5 is a feature release, bringing initial support for atomic operations (#168).
Low-level atomics that mimic Metal C are supported (atomic_store_explicit,
atomic_load_explicit, etc), as well as a higher-level Metal.@atomic that can be used to
update array values similar to how CUDA.jl's @atomic works. This uses native atomics when
supported, and falls back to a compare-exchange loop otherwise.

Minor changes include an update for the @device_code_agx disassembler, the addition of a
type variable to MtlArray encoding the storage mode (#194), and support for MPSVector
(#199) which should accelerate matrix/vector multiplications.

Also note that Metal.jl now disallows the construction of Float64 arrays, as these are not
support by the Metal libraries.

Closed issues:

• Support for atomics (#79)
• Make MtlArray storage mode a type parameter (#190)
• Long stacktrace when trying to create Float64 rand arrays (#205)
• allowscalar equivalent for Metal.jl (#206)
• Define map! ? (#219)
