Two different posts on the Zend Developer Zone today announce two different events surrounding Zend's framework - the release of the latest stable version, 1.0.4 and the posting of the latest Release Candidate, 1.5RC1.

About the Zend Framework 1.0.4 release:

It is our pleasure to announce the release of Zend Framework 1.0.4! You can download this new mini-release now from the Zend Framework download site. With this mini-release we bid a fond farewell to the 1.0 branch as we move on to the 1.5 release.

And about the Release Candidate:

This obviously marks a very important step towards a high-quality, thoroughly tested 1.5 GA release. Thanks to everyone who has contributed to this release in any way: with patches/check ins, documentation/translations, and bug reports.

You can grab this new Candidate from the download site as well.
