v1.1.13

Changed

• Acquire opam from GitHub release on Unix.

Fixed

• Turn off git directory ownership check.

v2.0.2

Changed

• Relax the restore keys for the opam cache.

v2.0.1

Changed

• Update the package index if the system package installation fails.

v2.0.0

Added

2.0.0-alpha

• Added support for 32 bits compiler variants.
• Added semver-style version matching support.
• Cache opam root (~/.opam on Unix, D:\.opam on Windows), opam download-cache (~/.opam/download-cache on Unix, D:\.opam\download-cache on Windows), and opam local switch (_opam).
• If dune-cache enabled, install dune, automatically configure the dune cache for the most efficient use in CI (exports DUNE_CACHE=enabled, DUNE_CACHE_TRANSPORT=direct. TRANSPORT must be direct, not daemon, to speed up the opam install process and to support Windows: ocaml/dune#4166, ocaml/dune#4167), and share the dune cache directory for each run.
• If opam-pin is enabled, pin the local packages specified by opam-local-packages.
• If opam-depext is enabled, install the system dependencies specified by opam-local-packages via depext
• If opam-disable-sandboxing is enabled, sandboxing is disabled for all platforms except Windows. (Sandboxing is always disabled on the Windows runners due to limitations of opam.)
• The profiling functionality allows us to check the duration of each group if debug mode is enabled. (https://docs.github.com/en/actions/managing-workflow-runs/enabling-debug-logging)

2.0.0-beta

• Added opam-repositories input to support multiple opam repositories.

2.0.0-beta10

• Added "extends" experimentally.

Changed

2.0.0-alpha

• The Windows runners install mingw64-i686-gcc-core and mingw64-i686-gcc-g++ for 32 bit compiler variant support.
• Clean the log output by grouping some operations.
• The compiler will be initialised in all platforms with an opam local switch to eliminate differences between platforms and prepare for full dependency caching in the future.
• The macOS and Ubuntu runners install and cache opam from the GitHub release directly without the system package manager.
• The macOS and Ubuntu runners install darcs and mercurial.
• The Windows runners install mercurial.
• Export OPAMCOLOR=always.
• Export OPAMERRLOGLEN=0.
• Export OPAMPRECISETRACKING=1.
• Export OPAMSOLVERTIMEOUT=500.
• Export OPAMROOT=D:\.opam on the Windows runners.
• Export OPAMVERBOSE=true if the actions debug mode is enabled. (https://docs.github.com/en/actions/managing-workflow-runs/enabling-debug-logging)
• Export MSYS=winsymlinks:native for @actions/cache on the Windows runners.
• Export HOME=%USERPROFILE% for opam on the Windows runners.

2.0.0-beta2

• Changed to force an update of the opam cache if the week number is changed.

2.0.0-beta3

• Use the week number to manage Cygwin cache.

2.0.0-beta4

• Set OPAMSOLVERTIMEOUT to 1000 to avoid a timeout even if the opam solver is slow.
• Increase cache hit ratio by loosening restore keys of opam cache.

2.0.0-beta5

• Reduce GitHub API calls to avoid issues that can easily hit rate-limiting.

2.0.0-beta6

• Unlock opam 2.1 on the Ubuntu and macOS runners.

2.0.0-beta8

• Use 2.1 mode instead of 2.0 mode on the Ubuntu and macOS runners.

2.0.0-beta9

• Increase the allowed artifact cache size from 5GB to 10GB.

2.0.0-beta10

• Remove some hacks as --no-depexts is now used in CLI 2.0 mode from opam 2.1.2.

2.0.0-beta13

• Do not install opam-depext if it's not enabled.

2.0.0

• Update default runtime to node16.

Removed

2.0.0-alpha

• The ocaml-version input has been removed. Use the ocaml-compiler instead.
• The simplified version specifying scheme (e.g. 4.12.0) support has been removed.

2.0.0-beta

• The opam-repository input has been removed in order to add the opam-repositories input.

2.0.0-beta2

• Removed the profiling functionality added in 2.0.0-alpha.

Fixed

2.0.0-alpha

• Use the appropriate file system behavior parameters on the Windows runners. (R2L:1, R2R:1)
• Add ppa: avsm/musl on 18.04 and older Ubuntu runners.
• Pass --enable-shell-hook to opam init fixes a bug that must be run via opam exec in subsequent steps.
• The Ubuntu runners install gcc-multilib, g++-multilib for ocaml-option-32bit.

2.0.0-beta3

• Set repository priorities correctly for multiple repositories feature.
• Lock the version of opam to be installed only to < 2.1 releases until opam 2.2 is released.

2.0.0-beta5

• If no user-input version is found in the opam-repository, explicitly raise an error instead of implicitly breaking the workflow.
• Retrieve the base compiler version from opam-repository to use the live released compiler version.

2.0.0-beta7

• Return an empty array to avoid depext failure when depext flags are not passed.

2.0.0-beta11

2.0.0-beta12

• Fallback to the version in which the assets exist if no assets exist in the latest opam release.
• Instruct Cygwin setup to use "sys" symlinks during setup (partial workaround for bug with native symlinks in Cygwin setup - some depexts may still be affected)

2.0.0-beta13

• Print a proper error if the version not found in the .ocamlformat file.

v2.0.0-beta13
