Where is 6.x-2.0-dev?

I'd love to know the answer on that question, but I'm puzzled myself.
6.x-2.x is currently being developed in HEAD
there is a release node for HEAD at http://drupal.org/node/94922, which should contain the nightly development snapshot of HEAD, but the attached tar ball hasn't been updated since march 2008 for some reason. I have to look into this

The only way to get the latest dev version is through CVS.
I'm also planning to release a Beta2 when I'm ready with #237147: usability tweaks for CAPTCHA admin, I hope in one of the coming days

I've also added a self made tar ball of the latest dev version, in case you're interested

Updating title and status of thread as the interim solution has been provided by soxofaan, after which this title may attract the attention of the maintainer to provide your longer term solution. :)

I'm the main maintainer of CAPTCHA right now, so this already had my attention ;)

I prefer to work in HEAD as long as there is no need to branch, to avoid double commits in order to keep two branches in sync, that's why there is no DRUPAL-6--2 branch (aka 6.x-2.x) for the moment and why I'd like to keep it that way. When Drupal 7 stabilizes, a DRUPAL-6--2 branch will be created and the Drupal 7 version will be developed in HEAD.

The reason for the brokenness of the HEAD release node is discussed in #89699: make release node form smarter when editing HEAD releases. It's not yet sure if it will be fixed, so maybe I'll have to create a DRUPAL-6--2 earlier after all.

To be continued...

Whoops, so you are! :)

That issue is interesting, but hasn't seen any actual progress in nearly two years, so yes, perhaps a -dev is in order. Interesting as just getting my head around this whole HEAD vs -dev thing myself, having just released the -dev version of my first module (Contrib Toggle) myself...

Here is 6.x-2.0-dev: http://drupal.org/node/94922
yay!
