Changes prefixed with "(*)" are potentially breaking to scripts or existing
repositories (changes that are automatically handled by the format upgrade tools
are not marked). Those prefixed with "(+)" are new command/option (since
2.1.0~alpha2).
2.1.0~rc:
* (*) Environment variables initialised only at opam client launch, no more via
libraries [#4606 #4703 @rjbou]
* (*) Deprecated `build-doc`, `build-test`, `make` flags [#4581 @rjbou]
* (+) Add `--confirm-level` and `OPAMCONFIRMLEVEL` for automatic answering
[#4582 @rjbou - fix #4168; #4683 @dra27 - fix #4682; #4691 @rjbou - fix #4682]
* (+) Add `--no` [#4582 @rjbou]
* (+) Add a `--with-0install-solver` option to the configure script to enable
the 'builtin-0install' solver [#4646 @kit-ty-kate]
* Add default cli mechanism: deprecated options are accepted (in the major
version) if no cli is specified [#4575 @rjbou]
* Add `opam config` deprecated subcommands in the default cli
[#4575 @rjbou - fix #4503]
* Add cli versioning for opam environment variables [#4606 @rjbou]
* Add cli versioning for enums of flags with predefined enums [#4606 @rjbou]
* Clearer messages about using --cli and OPAMCLI [#4655 @dra27]
* The options `--root` and `--switch` are now reflected in environment
variables when building packages so that calls to `opam` during build access
the correct root and switch [#4668 @LasseBlaauwbroek]
* Add cli versioning for enums of flags with predefined enums [#4626 @rjbou]
* Preprocess `--confirm-level` for plugins calls/install [#4694 @rjbou]
* Ensure the symlink for a plugin is maintained on each invocation
[#4621 @dra27 - partially fixes #4619]
* Initialise environment variables for plugins call/install [#4582 @rjbou]
* Expect plugins to end in .exe on Windows [#4709 @dra27]
* Introduce a `default-invariant` config field, restore the 2.0 semantics for
`default-compiler` [#4607 @AltGr]
* Fix default invariant with no system compiler [#4644 @AltGr - fix #4640]
* Perform an hard upgrade on intermediate roots, ie root from `2.1~alpha/beta`,
and keep a light upgrade from `2.0` [#4638 @rjbou]
* Send the 'opam root layout update' message to stderr [#4692 @AltGr]
* If opam root is different from the binary, allow reading it and try to read
in best effort mode [#4638 @rjbou - fix #4636]
* Don't check opam system dependencies on reinit after a format upgrade
[#4638 @rjbou]
* Fix `sys-ocaml-cc`, `sys-ocaml-arch` and `sys-ocaml-libc` when no system
compiler installed [#4706 @dra27]
* Fix `Not_found` (config file) in config report [#4570 @rjbou]
* Config report: Print variables of installed compilers and their (installed)
dependencies [#4570 @rjbou]
* Don't patch twice file [#4529 @rjbou]
* With `--deps-only`, set dependencies as root packages
[#4964 @rjbou - fix #4502]
* Keep global lock only if root format upgrade is performed
[#4612 @rjbou - fix #4597]
* Improve installation times by only tracking files listed in `.install`
instead of the whole switch prefix when there are no `install:` instructions
(and no preinstall commands)
[#4494 @kit-ty-kate @rjbou; #4667 @dra27 - fix #4422]
* Scrub OPAM* environment variables added since 2.0 from package builds to
prevent warnings when a package calls opam [#4663 @dra27 - fix #4660]
* Correct the message when more than one depext is missing [#4678 @dra27]
* Only display one conflict message when they are all owing to identical
missing depexts [#4678 @dra27]
* Don't exclude base packages from rebuilds (made some sense in opam 2.0 with
base packages but doesn't make sense with 2.1 switch invariants) [#4569 @dra27]
* Don't refer to base packages in messages any more
[#4623 @dra27 - fixes #4572]
* Give the correct command when demonstrating switch creation
[#4675 @dra27 - fixes #4673]
* On switch loading, if invariant is inferred and a write lock required, write
the file [#4638 @rjbou]
* Don't look for lock files for pin depends [#4511 @rjbou - fix #4505]
* Fetch sources when pinning an already pinned package with a different url
when using working directory [#4542 @rjbou - fix #4484]
* Don't ask for confirmation for pinning base packages (similarly makes no
sense with 2.1 switch invariants) [#4571 @dra27]
* Fix version pin source retrieving: mustn't error if archive opam file is
malformed [#4580 @rjbou]
* `opam list --silent` renamed to `--check` [#4595 @dra27 - fix #4323]

* Lint: Fix W59 & E60 for conf packages (no url required)
[#4550 @rjbou - fix #4549]
* Lint: Fix W59 & E60 with VCS urls, don't check upstream if url has VCS

* Lint: Fix manpage listing [#4708 @rjbou]
* Don't write lock file with `--read-only', `--safe`, and `--dryrun`
[#4562 @rjbou - fix #4320]
* Make `opam lock` consistent with `opam install`, on local pin always take
last opam file even if uncommitted [#4562 @rjbou - fix #4320]
* Opam file: Fix `features` parser [#4507 @rjbou]
* Opam file: Rename `hidden-version` to `avoid-version` [#4527 @dra27]

differentiate when it is not defined [#4638 @rjbou]
* Opam file: Differentiate bad format from bad (opam) version with
`Bad_version` exception, raised from `OpamFormat.check_opam_version`
[#4638 @rjbou]
* Opam file: Always print the `opam-version` field on files [#4638 @rjbou]

opam root [#4638 @rjbou - fix #4636]
* Opam file: Add `BestEffort` modules with reading functions that don't show
errors, given the `opam_file_format` internal field [#4638 @rjbou - fix #4636]
* Depext: Handle macport variants [#4509 @rjbou - fix #4297]
* Depext: Always upgrade all the installed packages when installing a new

--disable-checks is specified because configure is permitted to believe that
the MCCS library exists even if it couldn't detect it. [#3572 @dra27]

* Delay the removals of packages as much as possible, avoiding most cases of
mass uninstalled packages after a build failure
* Use a specific `opam` user-agent for downloads
* Remove globalisation of compiler package variables and support for
`available:` constraints depending on those. Rewrite the repository
accordingly to use explicit dependencies towards the compiler version.
2.0~alpha
* Changed license to LGPL 2.1 with linking exception, like OCaml (#2573)
* Track files installed by packages for cleaner removal and listing, add `opam
search --owns-file` (#502, #1215) *this requires packages to properly separate
build and install*, or unrelated files could get removed on package uninstall.

defined in `~/.opam/config`; include sample Linux wrappers to restrict process
permissions (e.g. ensure `build:` doesn't install)

the compiler package at installation)
* Discarded compiler files, `opam switch` now based on packages with the
`compiler` flag set
* Extended package configuration files
* Allow initialised opam without switch, initialised switch without compiler.
Better handling of compiler install failure
* (*) Large API rework, switch and repository state now handled separately, used in
functional style and avoiding many loads
* Git submodules are now automatically fetched by the git backend
* (*) Package definition files now prioritize `&` higher than `|`, like is most
common

* Url and description can now be included within a single package definition
`opam` file (#2328)

variables (#2337, #2361)
* Built-in support for alternative solver `mccs` (#2333)

* Non-system compiler definitions without source are now allowed

Actions are not aborted anymore on first failure when there is no
inter-dependency
* Rewritten parallel command execution engine
* Better display of actions, lots of improved messages
