Any estimates on when opam 2.2.0 will be released?

[ReallySnazzy]

I'm aware that this is an open source project for people without regular schedules, but I was hoping to ask and see if anyone has any guesses for when opam 2.2.0 will be released? My primary machine is Windows and I'd like to develop some small applications primarily for personal use, but a lot of documentation online suggests I should wait until the 2.2.0 release of opam.

We are trying to release an alpha this summer. it will indeed contain a lot of windows enhancement (cf.changes).

[XantreDev]

Any updates?

[rjbou]

The 2.2.0~alpha is in the pipeline. It should be released in the next days.

[XantreDev]

This is cool, but there are no windows executables

[rjbou]

Not for the moment. We will see if we can have windows executable available by the final release.
You can find install instructions in the release blog post

[XantreDev]

I can't build it. I followed instruction but has this error:

@MisterDA is this fixed by #5579 ?
