[-- Attachment #1.1: Type: text/plain, Size: 507 bytes --]

Hello,

I'm in the process of releasing guile-config 0.5, which unfortunately is
backward incompatible in some ways.

As a result I want to give developers who are using it a chance to
upgrade gradually.

To this end, in the attached patch, I add a new variable for 0.5. My
intention is to have 0.4.2 and 0.5 coexist for a while and then to
switch fully to 0.5 in due course.


Is this an acceptable way of doing a gradual transition to a backwards
incompatible version of the library?

Best wishes,

Alex

Definitely!  We’ve done that in the past for Guile-JSON, among others.

Should we commit it on your behalf?

Thanks,
Ludo’.

You can remove the ‘name’ here; users will then be able to type
guile-config@0.5 when they want this version.

There seems to be something wrong with the repo though:

Does the URL need an update?
