2.5.0

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 listener as a temporary connection error so unavailable database listeners honor connectionBackoff.
• 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, or poolMinConnections setting is configured, and cap warmup at the configured pool maximum.
