[Caml-list] [ANN] Beta release of OPAM 1.1.0

[Caml-list] [ANN] Beta release of OPAM 1.1.0

[Thomas Gazagnaire]

We are very happy to announce the beta release of OPAM version 1.1.0!
 
OPAM is a source-based package manager for OCaml. It supports multiple
simultaneous compiler installations, flexible package constraints, and
a Git-friendly development workflow which. OPAM is edited and
maintained by OCamlPro, with continuous support from OCamlLabs and the
community at large (including its main industrial users such as
Jane-Street and Citrix).
 
Since its first official release last March[1], we have fixed many
bugs and added lots of new features and stability improvements[2]. New
features go from more metadata to the package and compiler
descriptions, to improved package pin workflow, through a much faster
update algorithm. The full changeset is included below.
 
We are also delighted to see the growing number of contributions from
the community to both OPAM itself (35 contributors) and to its
metadata repository (100+ contributors, 500+ unique packages, 1500+
packages). It is really great to also see alternative metadata
repositories appearing in the wild (see for instance the repositories
for Android[3], Windows[4] and so on[5]). To be sure that the
community efforts will continue to benefit to everyone and to
underline our committment to OPAM, we are rehousing it at
`http://opam.ocaml.org` and switching the license to CC0 (see [6],
where 85 people are commenting on the thread).
 
The binary installer has been updated for OSX and x86_64:
- http://www.ocamlpro.com/pub/opam_installer.sh
 
You can also get the new version either from Anil's unstable PPA:
    add-apt-repository ppa:avsm/ppa-testing
    apt-get update
    sudo apt-get install opam
 
or build it from sources at :
- http://www.ocamlpro.com/pub/opam-full-1.1.0-beta.tar.gz
- https://github.com/OCamlPro/opam/releases/tag/1.1.0-beta
 
NOTE: If you upgrade from OPAM 1.0, the first time you will run the
new `opam` binary it will ugrade its internal state in an incompatible
way: THIS PROCESS CANNOT BE REVERTED. We have tried hard to make this
process fault-resistant, but failures might happen. In case you have
precious data in your ~/.opam folder, it is advised to backup that
folder before you upgrade to 1.1.
 
Happy hacking,
Thomas, on behalf on all the OPAM team

== CHANGES ==
* Automatic backup before any operation which might alter the list of installed packages
* Support for arbitrary sub-directories for metadata repositories
* Lots of colors

Re: [Caml-list] [ANN] Beta release of OPAM 1.1.0

[Anil Madhavapeddy]

For those curious about the package growth, I've plotted the results of
"opam-admin stats" here:

http://anil.recoil.org/2013/09/20/opam-1-1-beta.html

Also, I'd love to get any feedback about whether the beta PPAs in my
ppa-testing repository work well for you.  I'm still learning my way
around the (very powerful) system Canonical have, and I think this new
repository should work with Ubuntu Precise, Quantal and Raring on both
x86_64 and i386.  I'm still working my way through building ARM packages
for the rPi and Dreamplugs, since that's a more manual process.

cheers,
Anil

Re: [Caml-list] [ANN] Beta release of OPAM 1.1.0

[Prashanth Mundkur]

FYI, the source seems to require ocaml 4.0+ due to the use of
bin-annot.  It would be nice to support 3.12 too.

0.02s opam-core/opamScript.cmo [failed]
-- stderr of ocamlc.opt --
/usr/bin/ocamlc.opt: unknown option `-bin-annot'.

Re: [Caml-list] [ANN] Beta release of OPAM 1.1.0

[Thomas Gazagnaire]

This has been fixed in `master` (and thus will be fixed in the final release which should happen at the end of the week if no blocking bug pop-ups).

Best,
Thomas
