Changelog compared to 2.2.0~rc1:

Miscellaneous changes

Version

External dependencies

  • Always pass --no-version-check and --no-write-registry to Cygwin setup [#6046 @dra27]
  • Use --quiet-mode noinput for the internal Cygwin installation (which is definitely a fully-specified command line) and --quiet-mode unattended for external Cygwin installations (in case the user does need to select something, e.g. a mirror) [#6046 @dra27]

API updates

opam-state

  • OpamStateConfig.opamroot_with_provenance: restore previous behaviour to OpamStateConfig.opamroot for compatibility with third party code [#6047 @dra27]

⚠️ opam-full-2.2.0-1.tar.gz is equivalent to opam-full-2.2.0.tar.gz but contains the missing mccs archive as noted in #6066

2.2.0~alpha Pre-release
Pre-release

This is the alpha release of opam 2.2.0.

This alpha release contains new features, enhancements, updates & fixes. Please see blog post for main new features highlights and upgrade instructions.

Binaries and full archive are signed by by opam dev team (fingerprint 92C5 26AE 50DF 3947 0EB2 911B ED4C F1CA 67CB AA92).

Changelog (possibly scripts breaking changes are prefixed with ✘):

New features

Windows Support

Opam 2.2 comes with native Windows compatibility. You can now use opam from your preferred Windows terminal! We rely on the Cygwin UNIX-like environment for Windows as a compatibility layer, but it is possible for packages to generate native executables.

For more details, see blog post entry.

Recursive Pin

Recursive pinning allows to have opam lookup for opam files into subdirectories. It provides 2 new options --recursive and --subpath <path> that permit, respectively, to lookup recursively in directories, and to focus on a given directory. They can be combined.

For more details, see blog post entry.

Tree

opam tree show packages and their dependencies on a tree view. It can also display a reverse-dependency tree (through opam why, which is an alias to opam tree --rev-deps`), which can be useful to examine how dependency versions get constrained.

For more details, see blog post entry.

  • Add tree subcommand to display a dependency tree of currently installed packages [#5171 @cannorin - fix #3775]
  • Add why subcommand to examine how the versions of currently installed packages get constrained (alias to tree --rev-deps) [#5171 @cannorin - fix #3775]
  • tree subcommand now supports --json option [#5303 @cannorin - fix #5298]

Recommended development tools

There is now a way for a project maintainer to share their project developments tools: the with-dev-setup dependency flag. It is used in the same way as with-doc and with-test.

For more details, see blog post entry.

  • Add --dev-setup option to install recommended development tools from opam file (as with-test/with-doc), and its environment variable OPAMWITHDEVSETUP, and for post-messages [#5016 #5160 #5214 @rjbou - fix #4959]
  • Opam file: Add with-dev-setup variable for recommended tools [#5016 #5214 @rjbou]

Software Heritage binding

Opam now integrates a fallback to Software Heritage archive retrieval, based on SWHID. If an SWHID url is present in an opam file, the fallback can be activated.

For more details, see blog post entry.

Formula (experimental)

It is now possible to leverage the full expressivity of package dependency formulas from the command-line during switch creation and package operations.

  • Add --formula option to specify a formula to install [#4975 @AltGr]

New options

Pin

  • New option opam pin --current to fix a package to its current state (disabling pending reinstallations or removals from the repository) [#4973 @AltGr - fix #4970]
  • Add opam pin remove --all to remove all the pinned packages from a switch [#5308 @kit-ty-kate]
  • Allow opam pin remove to take a package (<pkg>.<version>) as argument [#5325 @kit-ty-kate]

Exec

Source

Clean

  • Add --untracked option to remove untracked files interactively [#4915 @rjbou - fix #4831] {2.1.3}

Switch

  • Add support for opam switch - that goes to previous selected global switch [#4910 @kit-ty-kate - fix #4688]
  • ✘ Change --base into --invariant, column name and the content is invariant formula installed dependencies [#5208 @rjbou]

Admin

  • Add opam admin add-constraint <cst> --packages to select a subset of packages to apply constraints [#5386 @rjbou - fix #3077]

Repository

  • Add OPAMREPOSITORYTARRING environment variable to enable repository tarring optimisation, it is disabled by default because it is an optimisation only on some os/configurations [#5015 @rjbou]

Enhancements, updates, and fixes

Initialisation

opam init

  • Run the sandbox check in the temporary directory [#4787 @dra27 - fix #4783] {2.1.1}

  • When a field is defined in switch and global scope, try to determine the scope also by checking switch selection [#5027 @rjbou] {2.1.3}
  • Resolve and use global config and environment variable before polling system informations (os, os-family, etc.) [#4892 @rjbou - fix #4883]

  • Open the release files when determining the distribution [#5568 @Leonidas-from-XIV

Fixes

  • Fix OPAMCURL and OPAMFETCH value setting [#5111 @rjbou - fix #5108]
  • Don't error when displaying if switch is not set [#5027 @rjbou - fix #5025] {2.1.3}
