This cycle, to address these problems for our ever-growing set of projects, the release management team is introducing a new tool for handling release notes as files in-tree, to allow us to simply and continuously build the release notes for stable branch point releases and milestones on the master branch. The idea is to use small YAML files, usually one per note or patch, to avoid merge conflicts on backports and then to compile those files in a deterministic way into a more readable document for readers. Files containing release notes can be including in patches directly, or you can create a separate patch with release notes if you want to document a feature than spans several patches. The tool is called Reno, and it currently supports ReStructuredText and Sphinx for converting note input files to HTML for publication. Reno is git branch-aware, so we can have separate release notes documents for each release series published together from the master build. -- Excerpted from Doug Hellmann's email to the mailing list http://lists.openstack.org/pipermail/openstack-dev/2015-November/078301.html For more information about Reno: http://docs.openstack.org/developer/reno/ Change-Id: I4028d52f5e67d2873b3dc9df279f78a15c35d84f
Barbican
Barbican is a REST API designed for the secure storage, provisioning and management of secrets. It is aimed at being useful for all environments, including large ephemeral Clouds.
Barbican is an OpenStack project developed by the Barbican Project Team with support from Rackspace Hosting, EMC, Ericsson, Johns Hopkins University, HP, Red Hat, Cisco Systems, and many more.
The full documentation can be found on the Barbican Developer Documentation Site.
If you have a technical question, you can ask it at Ask OpenStack with the barbican tag, or you can
send an email to the OpenStack General mailing list at
openstack@lists.openstack.org with the prefix [barbican] in the
subject.
To file a bug, use our bug tracker on Launchpad.
For development questions or discussion, hop on the OpenStack-dev mailing list
at openstack-dev@lists.openstack.org and let us know what you think, just add

#openstack-barbican on Freenode.
Barbican began as part of a set of applications that make up the CloudKeep ecosystem. The other systems are:
- Postern - Go based agent that provides access to secrets from the Barbican API.
- Palisade - AngularJS based web ui for the Barbican API.
- Python-barbicanclient - A convenient Python-based library to interact with the Barbican API.

Why Should You Use Barbican?
The current state of key management is atrocious. While Windows does have some decent options through the use of the Data Protection API (DPAPI) and Active Directory, Linux lacks a cohesive story around how to manage keys for application use.
Barbican was designed to solve this problem. The system was motivated by internal Rackspace needs, requirements from OpenStack and a realization that the current state of the art could use some help.
Barbican will handle many types of secrets, including:
- Symmetric Keys - Used to perform reversible encryption of data at rest, typically using the AES algorithm set. This type of key is required to enable features like encrypted Swift containers and Cinder volumes, encrypted Cloud Backups, etc.
- Asymmetric Keys - Asymmetric key pairs (sometimes referred to as public / private keys) are used in many scenarios where communication between untrusted parties is desired. The most common case is with SSL/TLS certificates, but also is used in solutions like SSH keys, S/MIME (mail) encryption and digital signatures.
- Raw Secrets - Barbican stores secrets as a base64 encoded block of data (encrypted, naturally). Clients can use the API to store any secrets in any format they desire. The Postern agent is capable of presenting these secrets in various formats to ease integration.
For the symmetric and asymmetric key types, Barbican supports full life cycle management including provisioning, expiration, reporting, etc. A plugin system allows for multiple certificate authority support (including public and private CAs).
Design Goals
- Provide a central secret-store capable of distributing secret / keying material to all types of deployments including ephemeral Cloud instances.
- Support reasonable compliance regimes through reporting and auditability.
- Application adoption costs should be minimal or non-existent.
- Build a community and ecosystem by being open-source and extensible.
- Improve security through sane defaults and centralized management of policies for all secrets.
- Out of band communication mechanism to notify and protect sensitive assets.
