v0.1.14

0.1.14 (2026-08-17)

This release focuses on observability and configurability improvements, adding OpenTelemetry/Prometheus metrics export and making cache and database pool settings tunable. A few dependency updates are included as well.

Features

• metrics:
  • Add support to export metrics in OpenTelemetry or Prometheus formats using metrics_utils crate (#72) by @SanchithHegde
  • Add metrics to instrument operations and system boundaries (#74) by @SanchithHegde
  • Add postgres pool connection lifecycle counters (#78) by @SanchithHegde

Refactors

• cache: Make TTL, TTI and max capacity of caches configurable (#75) by @SanchithHegde
• metrics: Unify all pull-based metrics as observable instruments and eliminate background collector (#79) by @SanchithHegde
• postgres: Allow configuring pool and connection timeouts (#76) by @SanchithHegde
• Migrate to use build_info and log_utils crates for build information and logging framework (#70) by @SanchithHegde

Documentation

• Add sample config file documenting all available configuration options (#73) by @SanchithHegde

Build System / Dependencies

• deps:
  • Pull hyperswitch_masking from crates.io instead of as a git dependency (#69) by @SanchithHegde
  • Upgrade dependencies (#71, #77) by @SanchithHegde

Database Migrations

No database migrations between v0.1.13 and v0.1.14.

Configuration Changes

This release includes the following configuration changes:

• Renames metrics_server section to metrics, and accepts a mode to allow exporting in either OTLP or Prometheus formats.
• Introduces a cache section to configure cache entry lifetimes and capacity.
• Adds database pool timeout configuration (max_lifetime_secs, idle_timeout_secs, connection_acquire_timeout_secs, connect_timeout_secs).

Refer to the config.example.toml file for more information.
