Release Notes

All releases are cumulative. Upgrading to the latest version includes all previous changes, so it's sufficient to install or run only the most recent release.

🏷️ v3.9.3

May 25, 2026

Changes

• Local agents upload through the nginx HTTPS proxy.
• Extensive DEBUG tracing of the query-text / execution-plan pipeline (observability only, no behavioral change).
• HTTP 204 accepted as a success status on metric writes.

🏷️ v3.9.2

May 21, 2026

Fixes

• Empty tag handling The agent now automatically strips empty tags before transmission. Previously, an empty tag could occasionally be sent to the platform, causing an insertion error in the metrics database.
• Application name sanitization The application_name value retrieved from pg_stat_activity is automatically added as a tag, but could sometimes contain special formats, that triggered an insertion error in the metrics database. The agent now strips any content enclosed in parentheses before transmitting the tag.

🏷️ v3.9.0

Feb 02, 2026

Changes

• Allows switching from an MD5-based query identifier to PostgreSQL’s native queryid. Refer to the documentation for more details.
• Added the DATASENTINEL_FOREGROUND environment variable to facilitate automatic startup via a systemd service.

🏷️ v3.8.0

Nov 12, 2025

Changes

• Fully compatible with the newest release, PostgreSQL Version 18.
• Updated third-party libraries.

Fixes

Solaris Compatibility for system_stats Extension: Resolved an issue where the current system_stats extension running on Solaris systems was missing certain metric fields.

🏷️ v3.7.0

Jun 9, 2025

Changes

The agent now includes the PostgreSQL listening port in the metadata it sends to the repository. This enables the repository to track database connection endpoints.

Fixes

• Extension Compatibility Update: The agent now detects the version of the pg_store_plans extension and adjusts its queries accordingly. It automatically runs the appropriate query to collect metrics based on the detected version. This ensures compatibility with version 1.9 (related to PostgreSQL 17), which includes renamed columns.

🏷️ v3.6.0

Oct 15, 2024

Changes

• Fully compatible with the newest release, PostgreSQL Version 17.
• Replaced WSGI CherryPy, a web framework, with Uvicorn, an ASGI web server optimized for handling asynchronous requests. The agent now includes a hard-coded limit for the maximum size of the api_calls.log file. The log file cannot exceed 10MB, ensuring better management of disk usage and avoiding unbounded growth
• Updated third-party libraries.
• Internal memory management improvements
