The installable version of CircleCI 2.2.0 includes the following improvements and changes:

• Fix setting for certain proxy configurations.

• Added support for 2.0 builders to use object storage other than S3 (mirroring the options from the 1.x releases).
• Support for private images in docker jobs, including support for ECR authentication.
• New VM service and build agent to address certain situations that resulted in build infrastructure failures.
• Better accommodations for using proxies throughout the core infrastructure.

• Added support for proxies to the VM Service/Remote Docker setup.
• Fixed an issue in the mongo migration scripts when moving from 1.x to 2.x that caused some customers problems.

CircleCI 2.0 is a completely updated CI/CD platform that starts every run with a clean image which is automatically provisioned just-in-time for Linux jobs on the CircleCI application installed in your private cloud. The CircleCI 2.0 platform includes significant performance, stability, and reliability improvements along with first-class Docker support, Workflows (pipelines), Resource Allocation, and Contexts. The Management Console (Replicated) also includes new options for enabling 2.0 Builders and appropriate default settings.

• Addresses an issue with CloudWatch metrics not being reported correctly.
• Address an issue with some build output being truncated in the UI.

• Fix issue where /etc/hosts was not being applied properly to every container.
• Add ability to configure VM instance type in AWS EC2 when configuring the VM Service in the Management Console.

• Addresses an issue with CloudWatch metrics not being reported correctly. UPDATE: some customers report this has not addressed their CloudWatch problems. The next release will have a new fix.

• Addresses an issue for installations pointing at github.com (rather than an instance of GitHub Enterprise) that prevented those installations from adding new projects.

• Fixes a bug that was causing lists of builds to be truncated in some circumstances.
• Fixes a bug where certain configurations of GitHub were not syncing email addresses properly.
• Fixes a bug where some users were seeing a beta UI that should have not have been showing up.
• Various minor UI fixes.

• Fixes a bug in new installs that prevented the first user from becoming an Admin.
• Fixes a bug with using the built-in Heroku deployment support.

• New Projects list in the Admin section gives you an overview of all projects across your entire installation of CircleCI Enterprise.
• New onboarding flow – new users will be prompted with a list of projects to follow drawn directly from their GitHub account.
• New option for users to choose “My builds” or “All builds” when viewing lists of builds.
• New JIRA integration for creating issues from a Build Page - configured under Project Settings.
• Option to externalize the underlying persistance storage (Postgres and Mongo) - talk to your CircleCI contact for details.
• Improved support for snapshot backup and restore via the Admin Console.
• Various performance improvements and minor bug fixes.

This is a security update to prevent logging temporary access tokens in build output. Those access tokens would have allowed a user to do a PUT request to overwrite an existing artifact only if all of the following were true:

A minor maintenance release, primarily to improve the single-box installation process for new trials of CircleCI Enterprise. Also, we have now follow advice from GitHub to not check if emails in GitHub Enterprise are “verified” — we will continue to check verified status if you are using github.com. If you have reason to change “verified” checks on your users’ emails let us know.

Note for Admins

This release requires extra steps than usual. Please see https://circleci.com/docs/enterprise/upgrade-for-1.46.x-and-earlier/ for detailed instructions.

The installable version of CircleCI 2.3.0 includes the following improvements and changes:

We have released patches to our AMIs and other infrastructure to address CVE-2016-8655. We recommend all CircleCI Enterprise installations follow the instructions below to update both their Services box and their Builder fleet.

• Fix for a bug causing builders to not honor CIRCLE_CONTAINERS_SUBNET when passed in the initialization.
• Builds with high parallelism were experiencing slow performance on the build detail page in the web UI – this should now be improved.
• Some emails generated by CircleCI had hard-coded links to circleci.com. These should now point at your installation host.
• A handful of minor UI fixes.

We have released patches to our AMIs and other infrastructure to address CVE-2016-5195. We recommend all CircleCI Enterprise installations follow the instructions below to update both their Services box and their Builder fleet.

• Fix for a bug that stopped certain CloudWatch metrics from working.

• Fix for a bug that caused UI problems for certain Pull Requests

• Minor changes to help debug some esoteric issues.

• Fixed layout problems in Safari on Mac.
• Fixed issue with tag builds interacting with the Auto-Cancel of Redundant Builds setting.
• Fixed performance of the build page, including awkward interaction when expanding build steps
• Fixed environment variables not sorting properly in project settings

• Note for Admins: we will now block your upgrade if there are pending migrations that need to be performed against your databases.
• We have changed the default behavior for builds with parallelism set above the current total container count in your build fleet. Previously we would auto-cancel any build with a parallelism above the total number of containers in your fleet. Those builds will now remain in the queue until the fleet is big enough to accommodate their parallelism setting. Builds behind those builds will continue to be bumped ahead, however, so the behavior is somewhat different than normal queuing behaviors, which is a strict FIFO model.
• New System Settings option to set the maximum parallelism for all projects. This allows you to prevent teams from using more of your fleet than intended.
• New option to auto-cancel “redundant” builds on a branch - found in the project settings, this new option allows you to set builds on branches other than your default branch to auto-cancel any builds on that same branch already running. This avoids running multiple simultaneous builds on the same working branch if you push several times in quick succession.
• On the Systems Settings page under Admin you can now enter “Container Tweaks” that will be run whenever containers are started in your build fleet. This feature allows you to make adjustments to the execution environment prior to builds running, so you can save time in each build. Note that these tweaks are only appropriate for things you want to apply to the environment for ALL of your builds.
• We now parse your circle.yml before the build runs and fail if there are errors. Before, the build would start and errors would be surfaced only once they caused a failure in a running build.
• Fixed a bug preventing artifacts from being generated in some circumstances after a failed build.
• The Artifacts API now allows cross-origin requests when requesting specific artifacts. In the past you could do this when using the API to get a list of your artifacts but not for downloading specific artifacts. You can now do both with the API.
• Fixed a bug that prevented some cases of triggering builds via the API. If you have had problems triggering builds with the API you may need to recycle your build fleet for this fix to take effect.
• Fixed a bug that would cause problems if someone’s access was removed from a project in GitHub Enterprise but that person’s token was being used by CircleCI Enterprise. Other users should now be able to continue using the project as expected if the original token’s owner no longer has access.
• Fixed a bug that prevented builds cancelled from the UI from actually cancelling in a timely fashion.
• Various design improvements such as better notifications and confirmation dialogs when changing various settings, new links on the build page and builds list to make it easier to link directly to specific containers or parts of your build output, better information for builds marked as “Not Run”, hiding some settings that aren’t applicable to Enterprise customers, and various minor improvements and bug fixes.

• Fix for an issue that was causing builds to fail that were triggered by users with a github account but no circleci account.

Note: we are shifting our versioning to better reflect the current release semantically.

• PR-only builds - We have added functionality to only run builds when a pull request is open. To enable this functionality you can navigate to “Advanced Settings” for your project and enable the “Only build pull requests” option.
• Chrome notifications - see the docs
• Fixed a bug where builds triggered by people who don’t have seats in CircleCI Enterprise were not running. They now should run as before.
• Some UI changes to make updating data in the web interface more consistent.
• Reliability improvements by changing retry logic in various places.

New Feature: The maximum size of files that you can upload for caching during builds has been fixed to 5G. The size is now bumped 20G by default on CircleCI Enterprise and customers can also override the default value to even larger size.

Bug fix: We’ve fixed a bug that --branch option was missing when --single-branch is used.

New Feature: Custom base URL for version control webhooks. When a new project is added, CircleCI will add a webhook to the GitHub repository of the project. With this new feature, you can override the default webhook base URL from the System Settings page under the Admin tools (available to designated administrative users). This feature is useful when your instance is behind firewall or other proxy and cannot directly receive webhooks from GitHub.

This release fixes a bug in the URL structure used to serve build artifacts.

• Please Note: If you are using OS X builds you will need to run a manual migration as part of this release. After upgrading you will need to run this in a REPL: (circle.backend.model.esxi-vm/run-migrations!). Please talk with your account manager if you need further instructions.
• The Admin Users page now has links to the builds of each user.
• The API has a new endpoint /api/v1/admin/licensing that returns information about the number of seats available, number being used, when the license will expire, and how many inactive users there are in the system.
• Fixed a bug where links to the documentation broke.
• Various small bug fixes and UI improvements.

Please make sure that you are using the latest provision-builder.sh and init-builder-0.2.sh before you upgrade to this release:
