Crowd 2.1 Beta 4 Release Notes

2010 年 11 月 19 日

We are working towards the launch of Crowd 2.1, with a number of new features and improvements. These release notes are for Crowd 2.1 Beta 4, which is now available for review. Crowd 2.1 Beta 4 contains all the features described in the Crowd 2.1 Beta 2 release notes as well as the improvements described below.

We would love your feedback on this beta release. See our download instructions and early adopter's guide below.

Crowd 2.1 Beta 3 was an internal release and was not made publicly available.

Do not use a beta release on production servers

Beta releases are not safe. A beta release is a snapshot of the ongoing Crowd development process. While we try to keep these releases stable, they have not undergone the same degree of testing as a full release.
Features in beta releases may be incomplete, or may change or be removed before the next full release.
Because beta releases represent work in progress, we cannot provide a supported upgrade path between beta releases or from any beta to the eventual final release. Therefore, you may not be able to migrate data stored in a Crowd beta release to a future Crowd release.

What's New in Crowd 2.1 Beta 4

IPv6 Support

Crowd 2.1 Beta 4 supports IPv6 and CIDR notation (RFC 4632). This improvement also fixes the problem reported in Beta 2, which prevented the use of IPv6 in client applications like JIRA and Confluence.

Fix for Nested Groups in Confluence

This releases includes a fix for CWD-1996: 'Crowd integration cache loses some nested groups'.

Targets for your Testing

We invite your feedback on this beta release, in particular on the following aspects:

The new REST APIs. See our overview of the new APIs and guide to the REST resources.
Database-backed LDAP caching. See the Crowd 2.1 Beta Guide to LDAP Caching.
We are keen to hear about any performance improvements or other impacts that you notice. Try tuning the polling interval and let us know what happens. We have optimised the database caching for directories containing approximately 10 000 (ten thousand) users. If your directory is significantly larger the new caching may not be as beneficial, but we are interested in hearing about the performance of larger directories too. When sending feedback, please include the following information:
- Your LDAP directory type (Active Directory, ApacheDS, Novell eDirectory, etc).
- The number of users, groups and average memberships per user in your directory.
- The time it takes to synchronise.
- Any other information you consider relevant, such as network topology, whether you are using SSL, and so on.
The fix for CWD-1996: 'Crowd integration cache loses some nested groups'.
If you are affected by CWD-1996, we are especially interested in your feedback on this fix. To test it, upgrade your Confluence installation to use version 2.1 Beta 4 of the Crowd integration client. (You do not need to upgrade your entire Crowd installation. Just the integration client is enough.) Please refer to CWD-1996 for instructions.
