What's New

Workspace Restructure

• Cargo workspace with 12 crates — the monolithic codebase has been restructured into a proper Cargo workspace under crates/, with clear dependency boundaries, per-crate feature flags, and independent compilation. This significantly improves build times for incremental development and makes the architecture easier to navigate.

SNS Queue Driver

• New sns queue driver — publish-only queue backend that pushes webhook jobs to an AWS SNS topic for fan-out to downstream consumers (SQS queues, Lambda functions, HTTP endpoints). Ideal for architectures where multiple services need to react to the same webhook events. Thanks to @lilfaf for the contribution.

Webhook Improvements

• Retry with exponential backoff — webhook delivery now retries with exponential backoff (1s, 2s, 4s, ...) for up to 5 minutes on non-2XX responses or network errors, matching the Pusher specification.
• 3-second disconnect delay — channel_vacated and member_removed webhooks are delayed 3 seconds with a re-check, so momentary disconnects or page navigations don't trigger spurious webhooks.

Performance

• Reduced lock contention — removed Mutex from Redis cache managers in favor of clone-based concurrency. Reduced global locks across cache, metrics, and queue subsystems.

Bug Fixes

• Fixed partial cluster channel counts in horizontal scaling
• Fixed webhook batching and filter handling
• Fixed Dockerfile for workspace crate structure
• Replaced deprecated axum_extra::Host with direct header extraction; removed axum-extra dependency
• Resolved clippy warnings

New Metrics

• Added process_max_fds metric for monitoring file descriptor limits

App Manager: Delta Compression Persistence

• All database app managers (MySQL, PostgreSQL, DynamoDB, ScyllaDB) now correctly persist and retrieve the channel_delta_compression field. Previously this field was silently dropped on read, causing delta compression config to be lost when apps were loaded from a database backend.

Documentation

• Added SNS queue driver documentation
• Added SNS environment variables and config reference
• Included docs site in the main repository
