What’s New in Release 2.19.00
- Before upgrading to Server v2.19 your Nomad launch configuration must be updated by following this guide. Server v2.19 uses Nomad version 0.9.3, so if you have externalized Nomad, contact your support engineer before upgrading.
You can now customize resource classes for your installation to provide developers with CPU/RAM options for the Jobs they configure. For more information see our guide to customizing resource classes in Server v2.19.
CircleCI Server installations on AWS can now be configured to work on GovCloud. Using AWS GovCloud enables you to meet a variety of regulatory requirements, such as FedRAMP, ITAR, DoD SRG, CJIS, and HIPAA. Read more about how CircleCI helps customers meet security and compliance needs here.
Upgrades and Fixes
For v2.19 we have updated Nomad clusters from 0.5x to 0.9, reducing the accumulation of dead jobs and improving overall performance. For more information, see the Nomad changelog.
The image used to run the RabbitMQ server has been updated to fix vulnerabilities.
The Server-Mongo-Upgrader service has been removed from the Services machine. Server Mongo Upgrader was a migration service written to facilitate the upgrade from Mongo 3.2 to 3.6, which was done as a part of the CircleCI Server v2.15.0 release in October 2018. This means it is not possible to upgrade directly from a Server version pre v2.15.0 to v2.19.0.
- If you are using an HTTP proxy for your installation, do not upgrade to v2.19.x until further notice. We have known issues around job step logging and docker commands customization that make the current 2.19.x releases incompatible with an HTTP proxy setup of CircleCI Server. This issue will be fixed in a future 2.19.x patch release and the ‘safe’ version will be flagged up clearly for affected customers.
