[ sent to caml-announce yesterday, but apparently this is not
automatically forwarded to caml-list ]
Dear OCaml users,
The release of OCaml version 4.03.0 is drawing near. We have
created a beta version for your testing pleasure. Please
use `opam switch 4.03.0+beta1` to install it, then test
your favourite software with it. Then let me know whether
it works for you.
We want to know about all bugs. Please report them at
http://caml.inria.fr/mantis/bug_report_page.php .
This beta version is available as source code at these addresses:
https://github.com/ocaml/ocaml/releases/tag/4.03.0%2Bbeta1
http://caml.inria.fr/pub/distrib/ocaml-4.03/
and will (very soon) be available as an OPAM switch.
Happy hacking,
-- Damien Doligez for the OCaml team.
OCaml 4.03.0:
-------------
(Changes that can break existing programs are marked with a "*")
Language features:
- PR#5528: inline records for constructor arguments (Alain Frisch)
- PR#6220, PR#6403, PR#6437, PR#6801:
Improved redundancy and exhaustiveness checks for GADTs.
Namely, the redundancy checker now checks whether the uncovered pattern
of the pattern is actually inhabited, exploding at most one wild card.
This is also done for exhaustiveness when there is only one case.
Additionally, one can now write unreachable cases, of the form,
"pat -> .", which are treated by the redundancy check. (Jacques Garrigue)
- PR#6374: allow "_ t" as a short-hand for "(_, _, ..) t" for n-ary type
constructors (Alain Frisch)
- PR#6714: allow [@@ocaml.warning] on most structure and signature items:
values, modules, module types
(whitequark)
- GPR#26: support for "(type a b)" as syntactic sugar for "(type a) (type b)"
(Gabriel Scherer)
- GPR#42: short functor type syntax: "S -> T" for "functor (_ : S) -> T"
(Leo White)
- GPR#88: allow field punning in object copying expressions:
{< x; y; >} is sugar for {< x = x; y = y; >}
(Jeremy Yallop)
- GPR#112: octal escape sequences for char and string literals
(Rafaël Bocquet)
- GPR#167: allow to annotate externals' arguments and result types so
they can be unboxed or untagged. Supports untagging int and unboxing
int32, int64, nativeint and float.
(Jérémie Dimino, Mark Shinwell)
- GPR240: replace special annotations on externals by attributes:
* "float" is generalized to [@@unboxed]
* "noalloc" becomes [@@noalloc]
Deprecate "float" and "noalloc".
(Jérémie Dimino)
- GPR#254: @ocaml.warn_on_literal_pattern attribute on constructors to
warn when the argument is matches against a constant pattern. This
attribute is applied on predefined exception constructors which
take an purely informational (with no stability guarantee) message.
(Alain Frisch)
- GPR#268: hexadecimal notation for floating-point literals
In OCaml source code, FP literals can be written using the hexadecimal
notation 0x<mantissa in hex>p<exponent> from ISO C99.
(Xavier Leroy)
- GPR#173: [@inline] and [@inlined] attributes (for function declarations
and call sites respectively) to control inlining
(Pierre Chambart, Mark Shinwell)

(Valentin Gatien-Baron, review by Jérémie Dimino)
- PR#6806: Allow type annotations before the "->" in "fun <args> -> <expr>"
(Valentin Gatien-Baron, review by Jérémie Dimino)
- GPR#282: change short-paths penalty heuristic to assign the same cost to
idents containing double underscores as to idents starting with an underscore
(Thomas Refis, Leo White)
- GPR#273: allow to get the extension slot of an extension constructor
by writing [%extension_constructor <path>]
(Jérémie Dimino)
- PR#6681 GPR#326: signature items are now accepted as payloads for
extension and attributes, using the syntax [%foo: SIG ] or [@foo: SIG ].
(Alain Frisch and Gabriel Radanne)
* GPR#342: Allow shortcuts for extension and attributes on all keywords.
The attribute in "let[@foo] .. in .." is now attached to the value binding,
not to the expression.
(Gabriel Radanne)
* GPR#234: allow "[]" as a user-defined constructor. Demand parenthesis
around "::" when using "::" as user-defined constructor.
(Runhang Li, review by Damien Doligez)
- GPR#188: accept [@@immediate] attribute on type declarations to mark types
that are represented at runtime by an integer

* GPR#170: Parse arbitrary precision integers.
Accept a single [A-Za-z] as modifier for integers (generalizing 'l','L','n')

This changes PR#6816 a little bit by reading the literal [123a] as a single
token that can later be rewritten by a ppx preprocessor.
