v0.7.0

rustfs-mimalloc v0.7.0

mimalloc V3 (v3.5.4) bindings for Rust.

Changed

• Breaking (rustfs-mimalloc-profiling): the default profiling core no
  longer selects an allocator. Install SamplingAllocator<A> around the
  application's GlobalAlloc provider. Both mimalloc::MiMalloc and
  rustfs_mimalloc::MiMalloc use the same recorder and pprof implementation.

• Keep the existing SamplingMiMalloc::new() and Default convenience API
  behind the explicit rustfs-allocator feature. Library adapters can depend
  on the core with default-features = false.

• Keep all three crate versions synchronized at 0.7.0 and refresh the locked
  libc resolution to 0.2.191. The pinned native allocator and ABI are unchanged.

• Restrict direct object parsing to uncompressed Linux ELF metadata, disabling
  unused format/compression features and removing the ruzstd decoder dependency.
  Backtrace symbolization keeps its existing features.

Added

• Stateful-provider forwarding contracts for alignment, zeroing, realloc
  failure/in-place/move outcomes and cross-thread free, with deterministic
  live-record rollback checks independent of provider size classes.
• A shared behavior/release test suite run from independent Cargo workspaces
  for both providers. Provider requirements come from root workspace dependencies;
  resolved dependency graphs reject accidental inclusion of a second allocator.
• Default-core, optional compatibility API and dual-provider validation of the
  normalized published archive, plus stable/Rust 1.95 and platform CI checks.
