In master, trying to build odoc docs with dune fails with:

Error: Conflicting implementations for virtual library "dune._wp":
- "dune._wp.dune" in _build/default/src/wp/dune-impl
- "dune._wp.jbuilder" in _build/default/src/wp/jbuilder-impl
Multiple rules generated for _build/default/_doc/_html/dune/Wp/.dune-keep:
- <internal location>
- <internal location>

A reasonable approach for now might be never to build docs for implementations of virtual libraries, since they all must share the same signature.

Given the restrictions going into dune 1.10 for virtual libraries (#2134), it might be possible to list the implementations available as part of the doc index generation step...

Yep, sounds like a good idea.

Given the restrictions going into dune 1.10 for virtual libraries (#2134), it might be possible to list the implementations available as part of the doc index generation step...

The restriction is only imposed on variants and not on virtual libraries. It will not be possible to list all implementations when building a virtual library.

Another option is to just include implementations in the generated index but link them to the virtual library with an appropriate note.

[new release] dune (1.10.0)
31f7a06 
CHANGES:

- Restricted the set of variables available for expansion in the destination
  filename of `install` stanza to simplify implementation and avoid dependency
  cycles. (ocaml/dune#2073, @aalekseyev, @diml)

- [menhir] call menhir from context root build_dir (ocaml/dune#2067, @ejgallego,
  review by @diml, @rgrinberg)

- [coq] Add `coq.pp` stanza to help with pre-processing of grammar
  files (ocaml/dune#2054, @ejgallego, review by @rgrinberg)

- Add a new more generic form for the *promote* mode: `(promote
  (until-clean) (into <dir>))` (ocaml/dune#2068, @diml)

- Allow to promote only a subset of the targets via `(promote (only
  <pred>))`. For instance: `(promote (only *.mli))` (ocaml/dune#2068, @diml)

- Improve the behavior when a strict subset of the targets of a rule is already
  in the source tree for projects using the dune language < 1.10 (ocaml/dune#2068, fixes
  ocaml/dune#2061, @diml)

- With lang dune >= 1.10, rules in standard mode are no longer allowed to
  produce targets that are present in the source tree. This has been a warning
  for long enough (ocaml/dune#2068, @diml)

- Allow %{...} variables in pps flags (ocaml/dune#2076, @mlasson review by @diml and
  @aalekseyev).

- Add a 'cookies' option to ppx_rewriter/deriver flags in library stanzas. This
  allow to specify cookie requests from variables expanded at each invocation of
  the preprocessor. (ocaml/dune#2106, @mlasson @diml)

- Add more opam metadata and use it to generate `.opam` files. In particular, a
  `package` field has been added to specify package specific information.
  (ocaml/dune#2017, ocaml/dune#2091, @avsm, @jonludlam, @rgrinberg)

- Clean up the special support for `findlib.dynload`. Before, Dune would simply
  match on the library name. Now, we only match on the findlib package name when
  the library doesn't come from Dune. Someone writing a library called
  `findlib.dynload` with Dune would have to add `(special_builtin_support
  findlib_dynload)` to trigger the special behavior. (ocaml/dune#2115, @diml)

- Install the `future_syntax` preprocessor as `ocaml-syntax-shims.exe` (ocaml/dune#2125,
  @rgrinberg)

- Hide full command on errors and warnings in development and show them in CI.
  (detected using the `CI` environment variable). Commands for which the
  invocation might be omitted must output an error prefixed with `File `. Add an
  `--always-show-command-line` option to disable this behavior and always show
  the full command. (ocaml/dune#2120, fixes ocaml/dune#1733, @rgrinberg)

- In `dune-workspace` files, add the ability to choose the host context and to
  create duplicates of the default context with different settings. (ocaml/dune#2098,
  @TheLortex, review by @diml, @rgrinberg and @aalekseyev)

- Add support for hg in `dune subst` (ocaml/dune#2135, @diml)

- Don't build documentation for implementations of virtual libraries (ocaml/dune#2141,
  fixes ocaml/dune#2138, @jonludlam)

- Fix generation of the `-pp` flag in .merlin (ocaml/dune#2142, @rgrinberg)

- Make `dune subst` add a `(version ...)` field to the `dune-project`
  file (ocaml/dune#2148, @diml)

- Add the `%{os_type}` variable, which is a short-hand for
  `%{ocaml-config:os_type}` (ocaml/dune#1764, @diml)

- Allow `enabled_if` fields in `library` stanzas, restricted to the
  `%{os_type}`, `%{model}`, `%{architecture}`, `%{system}` variables (ocaml/dune#1764,
  ocaml/dune#2164 @diml, @rgrinberg)

- Fix `chdir` on external and source paths. Dune will also fail gracefully if
  the external or source path does not exist (ocaml/dune#2165, fixes ocaml/dune#2158, @rgrinberg)

- Support the `.cc` extension fro C++ sources (ocaml/dune#2195, fixes ocaml/dune#83, @rgrinberg)

- Run `ocamlformat` relative to the context root. This improves the locations of
  errors. (ocaml/dune#2196, fixes ocaml/dune#1370, @rgrinberg)

- Fix detection of `README`, `LICENSE`, `CHANGE`, and `HISTORY` files. These
  would be undetected whenever the project was nested in another workspace.
  (ocaml/dune#2194, @rgrinberg)

- Fix generation of `.merlin` whenever there's more than one stanza with the
  same ppx preprocessing specification (ocaml/dune#2209 ,fixes ocaml/dune#2206, @rgrinberg)

- Fix generation of `.meriln` in the presence of the `copy_files` stanza and
  preprocessing specifications of other stanazs. (ocaml/dune#2211, fixes ocaml/dune#2206,
  @rgrinberg)

  case of syntax errors. (ocaml/dune#2223, @rgrinberg)

- In .merlin files, don't pass `-dump-ast` to the `future_syntax` preprocessor.
  Merlin doesn't seem to like it when binary AST is generated by a `-pp`
  preprocessor. (ocaml/dune#2236, @aalekseyev)

- `dune install` will verify that all files mentioned in all .install files
  exist before trying to install anything. This prevents partial installation of
  packages (ocaml/dune#2230, @rgrinberg)
