Dune 2.2.0

dune test is now a command alias for dune runtest. This is to make the CLI less idiosyncratic (#3006, @shonfeder)

Allow to set menhir flags in the env stanza using the menhir_flags field. (#2960, fix #2924, @bschommer)

By default, do not show the full command line of commands executed by dune when dune is executed inside dune. This is to make integration tests more reproducible (#3042, @diml)

dune subst now works even without opam files (#2955, fixes #2910, @fangyi-zhou and @diml)

Hint when trying to execute an executable defined in the current directory without using the ./ prefix (#3041, fixes #1094, @voodoos).

Extend the list of modifiers that can be nested under with-accepted-exit-codes with chdir, setenv, ignore-<outputs>, with-stdin-from and with-<outputs>-to (#3027, fixes #3014, @voodoos)

It is now an error to have a preprocessing dependency on a ppx rewriter library that is not marked as (kind ppx_rewriter) (#3039, @snowleopard).

Fix permissions of files promoted to the source tree when using the shared cache. In particular, make them writable by the user (#3043, fixes #3026, @diml)

Only detect internal OCaml tools with .opt extensions. Previously, this detection applied to other binaries as well (@kit-ty-kate, @rgrinberg, #3051).

Give the user a proper error message when they try to promote into a source directory that doesn't exist. (#3073, fix #3069, @rgrinberg)

Correctly build vendored packages in -p mode. These packages were incorrectly filtered out before. (#3075, @diml)

Do not install vendored packages (#3074, @diml)

make now prints a message explaining the main targets available (#3085, fix #3078, @diml)

Add a byte_complete executable mode to build programs as self-contained bytecode programs (#3076, fixes #1519, @diml)
