Dk 2.1.3 - Please upgrade!

THE DkML DISTRIBUTION HAS BEEN SUNSET

End-of-life is December 31, 2026.

In PowerShell do:

winget remove dkml

You’ll see Uninstall failed with exit code: 4294967295 but otherwise it should succeed.

Then do:

winget install dkml

winget upgrade and winget remove will fail with an innocuous error:
```
Uninstall failed with exit code: 4294967295
```
Just ignore the error and continue with winget install dkml. Issue: https://gitlab.com/dkml/distributions/dkml/-/issues/26.
The installer does not yet check that all OCaml programs are stopped before upgrading or uninstalling. If you get Permission denied then stop OCaml manually: close Visual Studio Code, stop any dune build, and stop any opam install / opam exec. And then forcibly kill the processes in PowerShell:
```
1..6 | % {  @("bash","sh","with-dkml","ocamllsp","git","opam","dune","ocamlrun") | % { taskkill /F /IM "$_.exe" }; Start-Sleep 1 }
```

Upgraded from opam 2.2.0 to opam 2.2.1.
The ocaml/opam-repository tag was advanced to Sep 10, 2024.
bugfix: dk Ml.Switch init was broken on Linux and macOS. DkML 2.1.2 had incorrectly pinned the dkml-host-abi and dkml-target-abi of the master DkML build machine. https://gitlab.com/dkml/distributions/dkml/-/issues/24
Allow prereleases of Visual Studio; requested at https://gitlab.com/dkml/distributions/dkml/-/issues/23.

You can continue to use dkml.exe and with-dkml.exe but both are deprecated; the new (unified) executable is dk.exe. See Deprecated Commands in the release notes.
Once every two weeks DkML news about new versions, errata, uninstalling, etc. will be shown on a webpage. It is triggered from the now deprecated dkml init, the replacement dk Ml.Switch init and the with-dkml proxy commands, and can be disabled with dk Ml.News disable. In particular, use dk Ml.News to show the news if you are experiencing problems with DkML.

The deprecated commands still work, but will first display the new command on the standard error and then pause for 15 seconds.

(1) with-dkml bash / with-dkml python3 / etc will not pause for 15 seconds.

dkml-target-abi-windows_x86_64 and similar 64-bit packages now conflict with ocaml-option-32bit, and 32-bit Linux/macOS/Win32 target packages depend on ocaml-option-32bit.
dk Ml.Use no longer pauses for 15 seconds since with-dkml bash / with-dkml python3 / etc is used frequently by opam install inside DkML switches.
