[opam-devel] OPAM 0.9.5 released

[Thomas Gazagnaire]

Hi,

I'm pleased to announce the release 0.9.5 of OPAM.  All the features that I though are important for the first releases are in, so you can consider 0.9.5 to be something like 1.0-rc1.

For this release, I'm particularly keen on getting people feebdack on the new auto-setup thing: OPAM now asks the user if he wants his local configuration upgraded to fully use OPAM (including installation auto-completion scripts). Use `opam init --no-setup` if you want to continue using OPAM as before.

One notable change which will please packagers of OPAM for OS distributions: I've added a `make with-ocamlbuild` and `make install-with-ocamlbuild` targets to not depend on the unreleased (and thus unpackaged) ocp-build. Otherwise, when using the development version of OPAM, it is still recommended to use ocp-build (as it is much faster). 

The changelog:
* If necessary, apply patches and substitute files before removing a package
* Fix `opam remove <pkg> --keep-build-dir` keeps the folder if a source archive is extracted
* Add build and install rules using ocamlbuild to help distro packagers
* Support arbitrary level of nested subdirectories in packages repositories
* Add `opam config exec "CMD ARG1 ... ARGn" --switch=SWITCH` to execute a command in a subshell
* Improve the behaviour of `opam update` wrt. pinned packages
* Change the default external solver criteria (only useful if you have aspcud installed on your machine)
* Add support for global and user configuration for OPAM (`opam config setup`)
* Stop yelling when OPAM is not up-to-date
* Update or generate `~/.ocamlinit` when running `opam init`
* Fix tests on *BSD (thx Arnaud Degroote)
* Fix compilation for the source archive
