  (Francois Berenger, Gabriel Scherer)

• Clarification and improvements to the documentation

  682, #685, #693

  (Florian Angeletti, Johannes Kloos, Michael Färber)

  724

  (Thibault Suzanne)

  734

  (Thibault Suzanne, review by Gabriel Scherer, request by Oscar Gauthier)

v2.5.3

Batteries 2.5.3 synchronizes library functions with OCaml 4.04+beta2, and will hopefully be an extension of the upcoming OCaml 4.04 release.

• Compatibility with OCaml 4.04. 5e63a9a756f (Gabriel Scherer)

v2.5.1, v2.5.2

Batteries 2.5.1 and 2.5.2 fix a silly packaging bug in Batteries 2.5.0.

v2.5.0

Batteries 2.5.0 is a minor release whose main change is that it is compatible with the newly released OCaml 4.03.

Note that Batteries 2.5.0 is compatible with older OCaml releases as well, and provides back-ported versions of most standard library functions made available in 4.03 only. For example, BatString.uppercase_ascii is usable under all OCaml versions.

If the documentation of a Batteries function says @since 2.5.0 then it is available under all supported OCaml version (3.12.1 and up). If it says @since 2.5.0 and OCaml 4.03.0 then it is only available under OCaml 4.03.0.

• BatTuple: add Tuple{N}.make : 'a1 -> ... -> 'an -> 'a1 ... 'an

  657

  (Thibault Suzanne)
• BatBig_int: fix sequence operators (--), (---) to avoid polymorphic comparison

  674, #675, #676

  (Pieter Goetschalckx and Cedric Cellier)
• Extend all Batteries module to cover OCaml 4.03 features
