links 6.x-1.0-beta3

Fully functional links_admin.module. Some new APIs in links.inc. Smarter updating when a link's title is changed in the master or node records. Removed an extraneous diagnostic message from links_weblink.module.

This is the initial beta release of links_admin.

Developers using the Links API, please read the CHANGELOG.txt file and API.html files, because the last couple of CVS commits have had some API changes. Most of the changes are backward-compatible, but there was one change between beta versions that is not backward-compatible because the API itself was wrong.
