Hi everyone,
opam 2.5.2 is now available. This release is fixing:
- a security issue (OSEC-2026-10)
- a regression from 2.5.1 preventing cross-compiled packages that use dune from installing properly (ocaml/dune#14393)
We invite everyone to upgrade to 2.5.2 as soon as possible.
If you depend on the older opam package of your preferred distribution, maintainers of distributions such as Debian Stable have been notified and we expect backporting of the relevant fixes to be available there very soon.
You can read our blog post for relevant links and details.
Try it!
The upgrade instructions are unchanged:
For Unix systems
bash -c "sh <(curl -fsSL https://opam.ocaml.org/install.sh) --version 2.5.2"
or from PowerShell for Windows systems
Invoke-Expression "& { $(Invoke-RestMethod https://opam.ocaml.org/install.ps1) } -Version 2.5.2"
Please report any issues to the bug-tracker.
Happy hacking,
