The Arvados team is pleased to announce Arvados v2.0.0. This is a
major upgrade, with many new features. Some older components have also
been deprecated or removed, superceded by newer components or APIs.

This release introduces an entirely new Arvados Workbench, called
“Workbench 2”, built using modern web technologies and based on user
feedback. It features:
Enhanced accessibility for the most important features
Better responsiveness, loading only data needed for display
Advanced tagging and searching of data collections with user-supplied metadata
The traditional Workbench also remains available.
Support for CWL 1.1
The Arvados workflow runner supports the latest Common Workflow
Language standard. CWL 1.1 adds optional secondary files on inputs,
and standardizes options to control work reuse, enable network access,
and load directory listing contents.
Improved keyword search
Keyword search now reliably returns expected results when searching
for parts of filenames.
New unified configuration file
Configuration has been reorganized into a single unified configuration
file at /etc/arvados/config.yml which is read by all components. This
streamlines installation and maintenance, and reduces opportunities
for error by eliminating redundancy.
New Cloud Dispatcher
The arvados-dispatch-cloud service manages the full lifecycle of VM
creation, container scheduling, and idle VM destruction for elastic
cloud computing. It replaces the previous approach of managing an
elastic SLURM cluster with Arvados Node Manager and
crunch-dispatch-slurm. SLURM is still supported for on-premise HPC
Install and Admin documentation overhaul
The installation and admin documentation have been substantially
updated and rewritten to be easier to follow and fill in gaps.
Centralized user management option
An organization with multiple Arvados clusters can now centralize user
management by designating one cluster to be the “LoginCluster” which
owns the user accounts for the federation. This enables users to log
in to any cluster in the federation with consistent identity,
credentials, and permissions.
Transfer ownership of user objects
An admin can now transfer ownership of all objects and permissions
from one user to another, for example to transition the work of a user
who is leaving the organization to another user.
Identify users by upstream email address
During login, users in Arvados are now looked up based on email
addresses supplied by the upstream login provider. This avoids the
need to migrate user accounts in order to switch from one login method
to another. Users can change email addresses provided the old email
address is retained as an alias.
Native Google login
The arvados-controller component now directly supports Google login
(as an alternative to redirecting to the SSO server). If you only
require Google login, you can now configure it in config.yml and
decommission the Arvados SSO server.
The admin can configure rules (“protected” and “original owner”) that
apply to specific user-defined properties on collections.
Support for Debian 10
Arvados now supports Debian 10 (“buster”).
Crunch v1 (jobs/pipelines API)
The legacy crunch v1 (“jobs”) infrastructure for running pipelines has
been removed. A read-only API remains to provide access to legacy
database records for installations that have them. Arvados
installations performed since the end of 2017 (v1.1.0) should only
have ever used the crunch v2 (“containers”) API, and are unaffected by
Although not removed from this release, the functionality of Arvados
Node Manager is superseded by the new arvados-dispatch-cloud service.
Ubuntu 14.04 and Debian 8
Ubuntu 14.04 and Debian 8 are no longer supported.
