We need a URL to test it, please.

Same problem.
It seems the encrypted signature is now 42.43 every time.

New day, new algo. Reversing.

[FiloSottile]

They are sticking to their guns, changed the scheme completely. Not-on-my-watch.

Win! It was not a new scheme, only a more obfuscated source code.

Committing... Then we will have to find better ways to push these.

[FiloSottile]

Fix ready on HEAD. @phihag release?

But we can't release each time... And we need letters back into version numbers!

[phihag]

@FiloSottile I am releasing right now. I'm not sure why we need letters in the version numbers. What's the problem with the current approach?

[FiloSottile]

People get confused about releases from the future, and they tend to assume
they have the latest if the date is today. Also, elegance, no?

[jaimeMF]

I'd also prefer to have letters/number in the version for multiple releases in the same day, from a user's point of view , a release like 2013.06.34 looks strange.

[yasoob]

yes i also agree with @FiloSottile do you remember there was also an issue opened by someone regarding the release number ? I guess by having the letters/numbers the users will not be confused.
