Dear OCaml users,

We are pleased to announce the 2.6.0 release of
OCaml batteries-included.

Batteries Included is a community-maintained standard library
extension, with a focus on performance, stability and compatibility.

Bug reports, pull requests and user feedback are warmly welcome, see the
project page at
https://github.com/ocaml-batteries-team/batteries-included/

The library's API documentation can be found at:
http://ocaml-batteries-team.github.io/batteries-included/hdoc2/

Batteries 2.6.0 is a minor release, compatible with OCaml 4.04.0.

As usual, Batteries 2.6.0 is compatible with older OCaml releases as well (until OCaml-3.12.1), and provides back-ported
versions of most standard library functions made available recently.

After an 'opam update' your will be able to do an
'opam upgrade batteries' an enjoy this new release.

Many thanks to the contributors for this release:
Florian Angeletti
Francois Berenger
Michael Färber
Oscar Gauthier
Ifaz Kabir
Johannes Kloos
Gabriel Scherer
Thibault Suzanne
