2.5.0, August 31st, 2026
- Update the Go runtime to 1.26.6.
- Add an optional OTLP metrics publisher for scheduled scrapes, so the metrics exporter can publish metrics to OTLP backends.
- Add an OTLP quickstart, architecture overview, deployment guidance, and troubleshooting documentation, and highlight OTLP publishing on the project homepage and README.
- Restart the exporter process when its configuration file changes, after validating the updated configuration.
- Avoid restarting for a transient configuration while an in-place configuration-file update is still being written.
- Treat
ORA-12541: TNS:no listeneras a temporary connection error so unavailable database listeners honorconnectionBackoff. - Add the exporter user's passwd entry to the godror container image, preventing concurrent Oracle Client connection creation from aborting when UID 1000 cannot be resolved.
- Enable godror's Oracle session pool whenever a
poolIncrement,poolMaxConnections, orpoolMinConnectionssetting is configured, and cap warmup at the configured pool maximum.
