v2.5.3

Highlights

This release brings the Python, TypeScript, Rust, and Go package version metadata into sync at 2.5.3 and rolls up the retry parity work that landed since v2.5.0. It also fixes the release packaging so optional middleware and bridge integrations do not become hard dependencies.

• Optional integration packages are not hard dependencies. OpenTelemetry and bridge-specific packages stay out of required package dependencies. The Go core module now depends only on github.com/google/uuid; OTEL is not required by default. TypeScript keeps OTEL/bridge packages as optional peers, and Python keeps bridge packages in extras/lazy imports.
• retry now preserves sync functions instead of forcing async wrappers. Python and TypeScript retry wrappers auto-detect sync callables, return synchronously, and block synchronously for retry sleeps and semaphore waits while preserving the existing async behavior.
• TypeScript retry now supports decorator and closure usage. The same retry implementation works as retry(...)(fn), as a standard TypeScript method decorator, and as a legacy experimentalDecorators method decorator while keeping the wrapped method signature and return type intact.
• Rust now has first-class retry support. abxbus::retry! supports sync and async free functions and methods with retry/backoff, per-attempt timeout, retry predicates, semaphore limits, semaphore scopes, and multiprocess semaphore coordination.
• Retry remains standalone across runtimes. The retry modules are documented and tested as usable without creating an EventBus or depending on bus state.
• Sync and async retry coverage was expanded across languages. Python, TypeScript, and Rust now have mirrored sync/async tests for retry attempts, backoff, error filtering, timeouts, semaphore behavior, reentrancy, multiprocess locking, standalone usage, and method/function wrapping.
• Rust crate imports now use abxbus. The Rust crate package name is abxbus while the repository directory remains abxbus-rust; docs and examples were updated accordingly.
• Retry docs were refreshed. The docs now show Python decorators, TypeScript closure wrappers, TypeScript @retry(...) decorators, Rust abxbus::retry!, and the supported sync/async callable forms for functions, methods, lambdas, and arrow functions where each language supports them.
