[Python-Dev] Python 2.1 release schedule (PEP 226)

We had our first PythonLabs meeting of the year yesterday, and we went
over the 2.1 release schedule. The release schedule is posted in PEP
We found that the schedule previously posted there was a bit too
aggressive, given our goals for this release, so we have adjusted the
dates somewhat. We have also decided on a date for the first alpha
release (previously unmentioned in the PEP). So, here are the
19-Jan-2001: First 2.1 alpha release
23-Feb-2001: First 2.1 beta release
01-Apr-2001: 2.1 final release
We're already in PEP freeze mode -- no more PEPs will be considered
for inclusion in 2.1. Below is a list of the PEPs that we are
currently considering, with some comments. But first some general
- The alpha release cycle is for testing of tentative features. Alpha
releases contain working code that we want to see widely tested;
however, it's possible that a feature present in an alpha release is
changed or even retracted in a later release.
- Beta releases represent a feature freeze -- after the first beta
release, we will resign ourselves to fixing bugs. Once beta 1 is
released, no new features will be introduced, and no features will
The alpha cycle is especially important for features (such as nested
scopes) that (may) introduce backwards incompatibilities. There may
be more than one alpha release depending on feedback on the alpha 1
release. (But having too many alpha releases is not good -- people
won't bother downloading.)
Thus, we can only introduce a new feature in beta 1 if we're very sure
that it is mature enough to stay without interface changes. The final
decision on all PEPs under consideration has to be made before the
beta 1 release.
The beta cycle is important to ensure stability of the final release.
Specific PEPs under consideration:

Actually, most of these won't be fulfilled in 2.1.
SD 205 pep-0205.txt Weak References Drake
Fred is still working on this. I hope Tim can assist. But
we may have to postpone this.
S 207 pep-0207.txt Rich Comparisons Lemburg, van Rossum
I'm pretty sure that this is a piece of cake now that the
coercion patches are checked in.
S 208 pep-0208.txt Reworking the Coercion Model Schemenauer
All checked in. Great work, Neil!
S 217 pep-0217.txt Display Hook for Interactive Use Zadka
Moshe, this was accepted ages ago. Would you mind
submitting a patch to SourceForge? If you don't champion
this (and nobody else does), we may have to postpone it
S 222 pep-0222.txt Web Library Enhancements Kuchling
This is really up to Andrew. It seems he plans to create
new modules, so he won't be introducing incompatibilities in
S 227 pep-0227.txt Statically Nested Scopes Hylton
Jeremy is still working on a proper implementation, which he
hopes to have ready in time for the first alpha release
S 229 pep-0229.txt Using Distutils to Build Python Kuchling
I just moved this from pie-in-the-sky to active. Andrew has
a working prototype, it just doesn't work 100% yet, so I'm

Still waiting for Barry to implement this, but it's pretty

Paul, what's up with this? Tim & I recommended to do
something simple and working, and then you disappeared from
the face of the earth.
