It'd be kind of nice if we had a deprecation policy written up.  Doesn't have to
be big and hardcore, but just some notes on what we are aiming for, and some
guidelines on how to get there.

Well, what are people *actually* doing? That's always a good basis for a policy
discussion...

comment:3 Changed 14 years ago by Jonathan Lange 

I *think* the advice on the street is "Deprecate in Release 2.n, remove in
Release 2.(n+1)"

Deprecation is done by issuing a DeprecationWarning using the warnings module.

This sounds fine to me :)

Perhaps with some guidelines to the effect that modules where this is regularly
going on or has recently gone on should be marked unstable?

glyph says, "We should have a time-based deprecation policy." (See #2352)

Also, having the policy means documenting and enforcing it.

I've written up a proposed compatibility policy. I think the real remaining challenge here is to get our release process back on track so that we can have an official point where it takes effect; and perhaps also to clean up the deprecation warnings listed there.

#3262 #3263 #3264 #3265 and #3266 have all been filed in response to the new thread at: ​http://twistedmatrix.com/pipermail/twisted-python/2008-April/017497.html

They have all been tagged with "deprecation-policy" and assigned to me.

This ticket is now functioning as the master ticket for the new work. I'm happy to consider #1216 superceded by the new keyword.

#3262 is not part of the deprecation policy work.

I've updated the description to reference these tickets so that it'll be a little easier to find them.

I would say that with #8082 we now have an official deprecation policy.

#3266 is there, but it talks about a very strange API ... and for me, the simple Vesion() object is enough
