4. What's cvs-news?

5. How it works?
When a developer commits a change, s/he puts a mark-up in the message, to make it a "news"
Each news contains tags, title, and optional body
Some tags are added automatically based on context
User name
Branch name
Project name
[NEWS:for-tango architecture] WSEndpointReference is refactored.
WSEndpointReference class is refactored to achieve higher performance. Because of this change, a few methods are deprecated...

6. Why?
To automate more
Machine readable CVS commits can drive a lot of things
Bug tracking system
Continuous integration
Publicizing projects
Less overhead = more productivity
To improve visibility for free
Helps grow the community
More things to show to people
Reduces the communication overhead
No more "when will your change go into Glassfish?" question

7. What can it do today? Simplify communication
Often someone else is waiting for your change
Use cvs-news instead of writing a separate
Just commit and be done
Benefits
Interested party can subscribe via RSS or e- mail
More detailed history information helps future development
No more "I'm sorry, I forgot to CC to you"
Example: a change in JAX-WS RI that affects Tango

8. What's being planned? Changelog generation for builds
A tool to scan the commit messages, then automatically generate "list of noteworthy changes"
Hudson integration
Bi-directional links to find out which build contains the change
Answers "Which WSIT build includes this JAXB fix?"
Automatic issue tracker update
When you put bug ID as a tag, the bug will be marked as fixed with cross-references

There's a lot of ways to take advantage of cvs- news
