Gateway Changelog

v1.2.9

2026-05-26

Improved

• Improved provider credential refresh reliability: targeted retry paths now force a fresh token-provider fetch, while normal delivery remains cache-first for lower latency.
• Added explicit runtime profile selection: small remains the default for private or light deployments, and public is for high-load deployments.
• Moved low-level queue, dispatch, provider, database-pool, and SQLite tuning into profile-owned defaults to reduce misconfiguration risk.
• Bound retained stats rows after persistence failures so transient storage pressure cannot grow memory without limit.

v1.2.8

2026-05-13

Improved

• Improved high-load message dispatch stability by fixing a pending dedupe cleanup timing bug that could cause intermittent failures during slower fanout writes.
• Added a clear 32-subscriber-per-channel limit response with structured error code and localized message.
• Added reproducible benchmark tooling for future gateway capacity checks.

v1.2.7

2026-05-10

Improved

• Strengthened SQLite, PostgreSQL, and MySQL upgrade checks with legacy-runtime migration scenarios, schema convergence checks, and post-upgrade read/write verification.
• Completed preflight, blackbox, and cross-database parity audit passes before release.

v1.2.6

2026-04-24

Improved

• Brought the current Gateway snapshot after v1.2.5 into the release line and aligned runtime version, package metadata, and diagnostic labeling.

v1.2.5

2026-04-22

Fixed

• Fixed private maintenance cleanup failures on SQLite builds that do not support DELETE ... LIMIT.

Improved

• Private transport profiles now advertise wss_port correctly when PUSHGO_PUBLIC_BASE_URL includes a custom external port.

v1.2.4

2026-04-22

Improved

• Private transport configuration is now explicit through PUSHGO_PRIVATE_TRANSPORTS / --private-transports, such as none, wss, or quic,tcp,wss.
• Runtime behavior now follows selected transports strictly: /private/ws is mounted only when wss is enabled, and QUIC/TCP listeners start only when selected.
• TLS dependency checks are transport-aware: QUIC requires cert+key; TCP requires cert+key only when TLS is not offloaded; WSS does not require private transport certs.

v1.2.3

2026-04-22

Improved

• Added profile-driven observability for diagnostics, structured Trace events, and runtime stats.
• Streamlined diagnostics around private-channel operations while unifying dispatch/runtime telemetry into stats and trace paths.
• Aligned Linux release artifacts and runtime container baseline on Debian bookworm-slim.

v1.2.2

2026-04-19

Improved

• Brought accumulated Gateway changes after v1.2.1 into the production release baseline and synchronized release documentation with diagnostic version metadata.

v1.2.1

2026-04-15

Improved

• Improved ACK + pull delivery reliability by caching provider wakeup deliveries before dispatch.
• Improved first-sync behavior for provider pull routes, reducing missed pulls after subscribe/sync.
• Improved provider-pull subscription initialization consistency across SQLite, PostgreSQL, and MySQL.

v1.2.0

2026-04-10

Improved

• Adopted SemVer release naming for Gateway.
• Added formal release notes and Changelog governance.
• Aligned wakeup title propagation across provider delivery paths.
• Improved private channel fallback reliability after ACK timeout.
