• Fix for a bug that deselected all projects when a new user logged in for the first time
• Fix for a bug that was preventing Workflows from working correctly when located behind a proxy
• Bug fixes and improvements for Contexts

The installable version of CircleCI 2.8.0 includes the following fixes and improvements:

• An issue involving pre-allocated remote docker, machine VM creation, and other VM usage on AWS when the on-host VM option is selected has been fixed.

• An issue with the VM provider timing out when waiting for SSH to connect has been fixed. This upgrade supersedes any custom values for the Number of SSH attempts for starting VM setting and adds an equivalent field named Timeout for waiting for SSH to connect to VM(s) that you must set.

The installable version of CircleCI 2.6.0 includes the following fixes and improvements:

• It is now possible to create multiple Contexts in the Organization Settings of the CircleCI app. See the Contexts documentation for details and naming conventions.

The installable version of CircleCI 2.5.0 includes the following fixes and improvements:

• This release fixes a problem with DNS resolution failure on alpine-based containers. This problem was observed in the 2.3 release and was fixed for some service containers in 2.4. The 2.5 update fixes the issue for all service containers.
• This release includes improvements to scaling and garbage collection in the VM Service that should improve performance for installations with heavy use of machine executors or remote Docker.

The installable version of CircleCI 2.4.0 includes the following improvements and changes:

• Audit logging - This feature makes available a downloadable log of system events from the CircleCI Admin dashboard. This is the first release of audit logging; more events and improved data in the logs will be delivered in subsequent releases. Find detailed information about the data fields for each event in the Audit Logging section of the Security Features document.

• LDAP integration - It is possible to enable a new CircleCI installation to authenticate users with OpenLDAP or Active Directory credentials. New installations may be configured to have users authenticate through LDAP, including Active Directory support. Refer to the Authentication document for instructions.

• New build-agent - The new build-agent fixes some cases in which users were unable to log into a running job with SSH.

• VM Service improvements - Autoscaling of the VM Service has been improved, so machine executors should have more consistent performance at scale.

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

• New visualization for Workflows - When you click on a workflow in the CircleCI application, a diagram appears with the relationship of your jobs to one another and the complete sequence of the workflow.
• Updates to the onboarding flow - We now show a new user only projects already building on CircleCI rather than a list of all projects found in source control. This change was made to prevent inadvertent adding of projects to CircleCI during the onboarding process. We also added a confirmation dialog for any user opting to follow more than six projects and made it clearer how to add new projects not yet building on CircleCI.
• Support for object stores other than S3 - CircleCI 2.2.0 now supports the same object store options that are supported in 1.x. This is a prerequisite to future releases that will allow non-AWS installations of CircleCI 2.x.
• Updates to the VM Service; ACTION MAY BE REQUIRED IF YOU ARE USING AWS - The VM service has been updated to use volumes rather than persistent instances. This change allows operators to accommodate Docker Layer Caching with a smaller number of long-running VMs. If you installed using the suggested IAM permissions from prior versions you must update your IAM permissions with this upgrade. Refer to the policy template for the complete set of permissions.
• New Contexts feature; ACTION MAY BE REQUIRED IF YOU ARE USING THE HIGH AVAILABILITY CONFIGURATION - The Contexts feature uses a HashiCorp Vault secure storage mechanism. If your installation is running in HA mode, HashiCorp Vault needs to be externalized similar to the Mongo and Postgres databases. Refer to the Configuring High Availability documentation for instructions.

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.

If you have CircleCI installed you may access CircleCI 2.0 features on your current installation with no restrictions under your current agreement and support level. However, you must contact your CircleCI account representative for assistance with upgrading, to obtain migration scripts, and to receive a new license channel.

• CircleCI 2.0.0 is only available on AWS and may be installed with Terraform or manually.
• Teams may create a CircleCI 2.0 .circleci/config.yml file in their repositories to add new 2.0 projects incrementally while continuing to build 1.0 projects which use a circle.yml configuration file.

Documentation for the installable 2.0 application is available at CircleCI 2.0 Documentation for the following topics:

• Administrator’s Overview
• Administration FAQ
• Security Features
• Installing CircleCI 2.0 on Amazon Web Services with Terraform
• Configuring High Availability
• Administrative Variables, Monitoring, and Logging
• Introduction to Nomad Cluster Operation
• Backing up CircleCI Data

This feature adds the used minutes to your Org Settings > Plan Settings page. This feature displays used minutes against Linux machines. It expands on our current functionality which shows minutes used against OS X machines and is located on the same page: Org Settings > Plan Settings.

Data appears for Orgs with a billing date after Aug 31, 2017. So, a new org will immediately see minutes used, and existing orgs will see the minutes used appear within the coming 30 days, depending on the billing date for your plan.

Today we updated our Xcode 9.0 beta 3 image to Xcode 9.0 beta 5 (build version 9M202q) with the latest simulators.

You can use this image by specifying Xcode 9.0 in your circle.yml:

machine:
  xcode:
    version: "9.0"

This image tag will be automatically upgraded when new betas are released by Apple, until the final release of Xcode 9.

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 and Android jobs on the hosted CircleCI application.

Configuration moves into the code in 2.0, so every developer can configure jobs directly in their working branch, teams can try new things without the risk of slowing anyone else down, and business leaders have the ability to operate large global teams with minimal overhead. CircleCI 2.0 prevents you from writing clean-up scripts because every run starts in the same state, eliminating the risk of polluting a test database or leaving files in places that cause problems for the next run.

The CircleCI 2.0 platform includes significant performance, stability, and reliability improvements along with the following new features:

• First-class Docker Support: Choose any image to run your job steps, customizable on a per-job basis on a particular Git branch. Speed up your run times with advanced layer caching. Build docker images with full docker CLI support and full support for docker compose. Support for all programming languages and custom environments that offer more predictable output. See Specifying Container Images for instructions.

• Workflows: Orchestrate jobs and steps with great flexibility using a simple set of new keys in your configuration. Share temporary files between jobs with workspaces for fan-in, fan-out, parallel, and sequential runs. Hold a workflow for a manual approval and restart a workflow from a failed job. See Orchestrating Workflows for details.

• Resource Allocation: Configure your CPU and RAM needs on a per-job basis at the branch level, see the resource_class documentation for instructions. Paid accounts may request this feature from their Customer Success Manager, non-paid users may request to get started by sending email to support@circleci.com.

• Insights: Access interactive charts and analyses in seconds. Visualize trends in your build history to identify and pinpoint bottlenecks. Understand all of your builds at a glance. View the builds that fail most, so you can fix the slowest tests to improve efficiency. See the Collecting Test Metadata documentation for information.

• Debugging with SSH and CLI: Perform local job runs, configuration validation and SSH in to builds for access to log files and debugging running processes. See Using the CLI documentation to learn about running local jobs and refer to Debugging Jobs over SSH for SSH instructions.

• Parallelism: Automatic provisioning of containers as they are freed without waiting for other jobs to finish. See the Parallel Job Execution documentation for examples.

• Advanced Caching: Speed up builds by caching files from run to run using keys that are easy to control with granular caching options for cache save and restore points throughout your jobs. Cache any files from run to run using keys you can control, see the Caching Dependencies documentation for strategies and steps.

• Demonstration Applications: See the Language Guides and Demo Repos to learn CircleCI configuration by example for applications written in Go, Javascript, PHP, Python (Django and Flask), Ruby on Rails, Java, Elixir, and Clojure.

• New Documentation: New and restructured documentation including an Overview, Hello World, Sample 2.0 config.yml File, simplified instructions for Migrating from 1.0 to 2.0, plus examples for Configuring Databases and Creating Custom Docker Images. Refer to the Migration FAQ for common questions and known limitations.

Today we updated our Xcode 9.0 beta image to Xcode 9.0 beta 2 with the latest 10.2 simulators. To start using it, add the following to your circle.yml:

  xcode:
    version: "9.0"

This image tag will be upgraded automatically when new betas are released by Apple, until the final release of Xcode 9.

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:

1. They already had access to the build.
2. They identified the token in the build output.
3. The were to use the token within 30 minutes after the original artifact was uploaded.
