Releasing Icinga DB v1.5.1

Today we are announcing the release of Icinga DB version 1.5.1. This release addresses the issue of leaking SQL prepared statements when Icinga DB is configured as a source for Icinga Notifications.

Each time the custom variables for an Icinga Notifications event were fetched, a new prepared statement was executed by the database. Unfortunately, this prepared statement was not closed, resulting in an increasing number of open prepared statements until the database refuses to create any more. This effectively blocked both Icinga DB and potentially the entire database management system.

This bug does not affect those who are not using the Icinga Notifications source.

Additionally, dependencies were updated.

• Close Prepared Statement in Icinga Notifications Source. #1051
• Use icinga/icinga2:edge container image for testing. #1048
• Update dependencies. 11 times

Packages are already available on the package servers. We would kindly ask you to upgrade, especially if you are using Icinga Notifications with Icinga DB.
