Objective Caml 3.12.0:
----------------------
(Changes that can break existing programs are marked with a "*" )
Language features:
- Shorthand notation for records: in expressions and patterns,
{ lbl } stands for { lbl = lbl } and { M.lbl } for { M.lbl = lbl }
- Record patterns of the form { lbl = pat; _ } to mark that not all
labels are listed, purposefully. (See new warning below.)
- Explicit naming of a generic type; in an expression
"fun ... (type t) ... -> e", the type t is considered abstract in its
scope (the arguments that follow it and the body of the function),
and then replaced by a fresh type variable. In particular, the type
t can be used in contexts where a type variable is not allowed
(e.g. for defining an exception in a local module).
- Explicit polymorphic types and polymorphic recursion. In let
definitions, one can write an explicit polymorphic type just
immediately the function name; the polymorphism will be enforced,
and recursive calls may use the polymorphism.
The syntax is the same as for polymorphic methods:
"let [rec] <ident> : 'a1 ... 'an. <typexp> = ..."
- First-class packages modules.
New kind of type expression, for packaged modules: (module PT).
New kind of expression, to pack a module as a first-class value:
(module MODEXPR : PT).
New kind of module expression, to unpack a first-class value as a module:
(val EXPR : PT).
PT is a package type of the form "S" or
"S with type t1 = ... and ... and type tn = ..." (S refers to a module type).
- Local opening of modules in a subexpression.
Syntax: "let open M in e", or "M.(e)"
- In class definitions, method and instance variable override can now
be made explicit, by writing "method!", "val!" or "inherit!" in place of
"method", "val" and "inherit". It is an error to override an
undefined member (or to use overriding inheritance when nothing get
overridden). Additionally, these constructs disactivate respectively
warnings 7 (method override, code 'M') and 13 (instance variable
override, code 'V'). Note that, by default, warning 7 is inactive
and warning 13 is active.
- "Destructive" substitution in signatures.
By writing "<signature> with type t := <typeconstr>" and
"<signature> with module M := <module-path>" one replaces "t" and "M"
inside the signature, removing their respective fields. Among other
uses, this allows to merge two signatures containing identically
named fields.
* While fixing PR#4824, also corrected a gaping hole in the type checker,
which allowed instantiating separately object parameters and instance
variables in an interface. This hole was here since the beginning of
ocaml, and as a result many programs using object inheritance in a non
trivial way will need to be corrected. You can look at lablgtk2 for an
example.
Compilers and toplevel:
- Warnings are now numbered and can be switched on and off individually.
The old system with letters referring to sets of warnings is still
supported.
- New warnings:
+ 9 (code 'R') to signal record patterns without "; _" where
some labels of the record type are not listed in the pattern.
+ 28 when giving a wildcard argument to a constant constructor in
a pattern-matching.
+ 29 when an end-of-line appears unescaped in a string constant.
+ 30 when the same constructor or record field is defined twice in
mutually-recursive type definitions.
* The semantics of warning 7 (code 'M', method override) have changed
(it now detects all overrides, not just repeated definitions inside
the same class body), and it is now inactive by default.
- Better error report in case of unbound qualified identifier: if the module
is unbound this error is reported in the first place.
- Added option '-strict-sequence' to force left hand part of sequence to have
type unit.
- Added option '-no-app-funct' to turn applicative functors off.
This option can help working around mysterious type incompatibilities
caused by the incomplete comparison of applicative paths F(X).t.
Native-code compiler:
- AMD64: shorter and slightly more efficient code generated for
float comparisons.
Standard library:
- Format: new function ikfprintf analoguous to ifprintf with a continuation
argument.
* PR#4210, #4245: stricter range checking in string->integer conversion
functions (int_of_string, Int32.of_string, Int64.of_string,
Nativeint.of_string). The decimal string corresponding to
max_int + 1 is no longer accepted.
- Scanf: to prevent confusion when mixing Scanf scanning functions and direct
low level input, value Scanf.stdin has been added.
* Random: changed the algorithm to produce better randomness. Now passes the
DieHard tests.
- Map: implement functions from Set that make sense for Map.
Other libraries:
* Str: letters that constitute a word now include digits 0-9 and
underscore _. This changes the interpretation of '\b' (word boundary)
in regexps, but is more consistent with other regexp libraries. (PR#4874).
Ocamlbuild:
- Add support for native dynlink.
New tool:
- ocamlobjinfo: displays various information, esp. dependencies, for
compiled OCaml files (.cmi, .cmo, .cma, .cmx, .cmxa, .cmxs, and bytecode
executables). Extends and makes more official the old objinfo tool
that was installed by some OCaml packages.
All tools:
- PR#4857: add a -vnum option to display the version number and nothing else

Objective Caml 3.11.0:
----------------------
(Changes that can break existing programs are marked with a "*" )
Language features:
- Addition of lazy patterns: "lazy <pat>" matches suspensions whose values,
after forcing, match the pattern <pat>.
- Introduction of private abbreviation types "type t = private <type-expr>",
for abstracting the actual manifest type in type abbreviations.
- Subtyping is now allowed between a private abbreviation and its definition,
and between a polymorphic method and its monomorphic instance.
Compilers:
- The file name for a compilation unit should correspond to a valid
identifier (Otherwise dynamic linking and other things can fail, and
a warning is emitted.)
* Revised -output-obj: the output name must now be provided; its
extension must be one of .o/.obj, .so/.dll, or .c for the
bytecode compiler. The compilers can now produce a shared library
(with all the needed -ccopts/-ccobjs options) directly.
- -dtypes renamed to -annot, records (in .annot files) which function calls
are tail calls.
- All compiler error messages now include a file name and location, for
better interaction with Emacs' compilation mode.
- Optimized compilation of "lazy e" when the argument "e" is
already evaluated.
- Optimized compilation of equality tests with a variant constant constructor.
- The -dllib options recorded in libraries are no longer ignored when
-use_runtime or -use_prims is used (unless -no_auto_link is
explicitly used).
- Check that at most one of -pack, -a, -shared, -c, -output-obj is
given on the command line.
- Optimized compilation of private types as regular manifest types
(e.g. abbreviation to float, float array or record types with only
float fields).
Native-code compiler:
- New port: Mac OS X / Intel in 64-bit mode (configure with -cc "gcc -m64").
- A new option "-shared" to produce a plugin that can be dynamically
loaded with the native version of Dynlink.
- A new option "-nodynlink" to enable optimizations valid only for code
that is never dynlinked (no-op except for AMD64).
- More aggressive unboxing of floats and boxed integers.
- Can select which assembler and asm options to use at configuration time.
Run-time system:
- New implementation of the page table describing the heap (two-level
array in 32 bits, sparse hashtable in 64 bits), fixes issues with address
space randomization on 64-bit OS (PR#4448).
- New "generational" API for registering global memory roots with the GC,
enables faster scanning of global roots.
(The functions are caml_*_generational_global_root in <caml/memory.h>.)
- New function "caml_raise_with_args" to raise an exception with several
arguments from C.
- Changes in implementation of dynamic linking of C code:
under Win32, use Alain Frisch's flexdll implementation of the dlopen
API; under MacOSX, use dlopen API instead of MacOSX bundle API.
- Programs may now choose a first-fit allocation policy instead of
the default next-fit. First-fit reduces fragmentation but is
slightly slower in some cases.
Standard library:
- Parsing library: new function "set_trace" to programmatically turn
on or off the printing of a trace during parsing.
- Printexc library: new functions "print_backtrace" and "get_backtrace"
to obtain a stack backtrace of the most recently raised exception.
New function "record_backtrace" to turn the exception backtrace mechanism
on or off from within a program.
- Scanf library: fine-tuning of meta format implementation;
fscanf behaviour revisited: only one input buffer is allocated for any
given input channel;
the %n conversion does not count a lookahead character as read.
Other libraries:
- Dynlink: on some platforms, the Dynlink library is now available in
native code. The boolean Dynlink.is_native allows the program to
know whether it has been compiled in bytecode or in native code.
- Bigarrays: added "unsafe_get" and "unsafe_set"
(non-bound-checking versions of "get" and "set").
- Bigarrays: removed limitation "array dimension < 2^31".
- Labltk: added support for TK 8.5.
- Num: added conversions between big_int and int32, nativeint, int64.
More efficient implementation of Num.quo_num and Num.mod_num.
- Threads: improved efficiency of mutex and condition variable operations;
improved interaction with Unix.fork (PR#4577).
- Unix: added getsockopt_error returning type Unix.error.
Added support for TCP_NODELAY and IPV6_ONLY socket options.
- Win32 Unix: "select" now supports all kinds of file descriptors.
Improved emulation of "lockf" (PR#4609).
Tools:
- ocamldebug now supported under Windows (MSVC and Mingw ports),
but without the replay feature. (Contributed by Dmitry Bely
and Sylvain Le Gall at OCamlCore with support from Lexifi.)
- ocamldoc: new option -no-module-constraint-filter to include functions
hidden by signature constraint in documentation.
- ocamlmklib and ocamldep.opt now available under Windows ports.
- ocamlmklib no longer supports the -implib option.
- ocamlnat: an experimental native toplevel (not built by default).
Camlp4:
* programs linked with camlp4lib.cma now also need dynlink.cma.

- Major GC and heap compaction: fixed bug involving lazy values and
out-of-heap pointers.
- PR#3915: updated most man pages.
- PR#4261: type-checking of recursive modules
- PR#4308: better stack backtraces for "spontaneous" exceptions such as

Objective Caml 3.10.0:
----------------------
(Changes that can break existing programs are marked with a "*" )
Language features:
- Added virtual instance variables in classes "val virtual v : t"
* Changed the behaviour of instance variable overriding; the new
definition replaces the old one, rather than creating a new
variable.
New tools:
- ocamlbuild: compilation manager for OCaml applications and libraries.
See draft documentation at http://gallium.inria.fr/~pouillar/
* Camlp4: heavily revised implementation, new API.
New ports:
- MacOS X PowerPC 64 bits.
- MS Windows 64 bits (x64) using the Microsoft PSDK toolchain.
- MS Windows 32 bits using the Visual Studio 2005 toolchain.
Compilers:
- Faster type-checking of functor applications.
- Referencing an interface compiled with -rectypes from a module
not compiled with -rectypes is now an error.
- Revised the "fragile matching" warning.
Native-code compiler:
- Print a stack backtrace on an uncaught exception.
(Compile and link with ocamlopt -g; execute with OCAMLRUNPARAM=b.)
Supported on Intel/AMD in 32 and 64 bits, PPC in 32 and 64 bits.
- Stack overflow detection on MS Windows 32 bits (courtesy O. Andrieu).
- Stack overflow detection on MacOS X PPC and Intel.
- Intel/AMD 64 bits: generate position-independent code by default.
- Fixed bug involving -for-pack and missing .cmx files (PR#4124).
- Fixed bug causing duplication of literals (PR#4152).
Run-time system:
- C/Caml interface functions take "char const *" arguments
instead of "char *" when appropriate.
- Faster string comparisons (fast case if strings are ==).
Standard library:
- Refined typing of format strings (type format6).
- Printf, Format: new function ifprintf that consumes its arguments
and prints nothing (useful to print conditionally).
- Scanf:
new function format_from_string to convert a string to a format string;
new %r conversion to accomodate user defined scanners.
- Filename: improved Win32 implementation of Filename.quote.
- List: List.nth now tail-recursive.
- Sys: added Sys.is_directory. Some functions (e.g. Sys.command) that
could incorrectly raise Sys_io_blocked now raise Sys_error as intended.
- String and Char: the function ``escaped'' now escapes all the characters
especially handled by the compiler's lexer (PR#4220).
Other libraries:
- Bigarray: mmap_file takes an optional argument specifying
the start position of the data in the mapped file.
- Dynlink: now defines only two modules, Dynlink and Dynlinkaux (internal),
reducing risks of name conflicts with user modules.
- Labltk under Win32: now uses Tcl/Tk 8.4 instead of 8.3 by default.
- VM threads: improved performance of I/O operations (less polling).
- Unix: new function Unix.isatty.
- Unix emulation under Win32:
fixed incorrect error reporting in several functions (PR#4097);
better handling of channels opened on sockets (PR#4098);
fixed GC bug in Unix.system (PR#4112).
Documentation generator (OCamldoc):
- correctly handle '?' in value names (PR#4215)
- new option -hide-warnings not to print ocamldoc warnings
Lexer generator (ocamllex): improved error reporting.
License: fixed a typo in the "special exception" to the LGPL.

Objective Caml 3.09.0:
----------------------
(Changes that can break existing programs are marked with a "*" )
Language features:
- Introduction of private row types, for abstracting the row in object
and variant types.
Type checking:
- Polymorphic variants with at most one constructor [< `A of t] are no
longer systematically promoted to the exact type [`A of t]. This was
more confusing than useful, and created problems with private row
types.
Both compilers:
- Added warnings 'Y' and 'Z' for local variables that are bound but
never used.
- Added warning for some uses non-returning functions (e.g. raise), when they
are passed extra arguments, or followed by extra statements.
- Pattern matching: more prudent compilation in case of guards; fixed PR#3780.
- Compilation of classes: reduction in size of generated code.
- Compilation of "module rec" definitions: fixed a bad interaction with
structure coercion (to a more restrictive signature).
Native-code compiler (ocamlopt):
* Revised implementation of the -pack option (packing of several compilation
units into one). The .cmx files that are to be packed with
"ocamlopt -pack -o P.cmx" must be compiled with "ocamlopt -for-pack P".
In exchange for this additional constraint, ocamlopt -pack is now
available on all platforms (no need for binutils).
* Fixed wrong evaluation order for arguments to certain inlined functions.
- Modified code generation for "let rec ... and ..." to reduce compilation
time (which was quadratic in the number of mutually-recursive functions).
- x86 port: support tail-calls for functions with up to 21 arguments.
- AMD64 port, Linux: recover from system stack overflow.
- Sparc port: more portable handling of out-of-bound conditions
on systems other than Solaris.
Standard library:
- Pervasives: faster implementation of close_in, close_out.
set_binary_mode_{out,in} now working correctly under Cygwin.
- Printf: better handling of partial applications of the printf functions.
- Scanf: new function sscanf_format to read a format from a
string. The type of the resulting format is dynamically checked and
should be the type of the template format which is the second argument.
- Scanf: no more spurious lookahead attempt when the end of file condition
is set and a correct token has already been read and could be returned.
Other libraries:
- System threads library: added Thread.sigmask; fixed race condition
in signal handling.
- Bigarray library: fixed bug in Array3.of_array.
- Unix library: use canonical signal numbers in results of Unix.wait*;
hardened Unix.establish_server against EINTR errors.
Run-time system:
- Support platforms where sizeof(void *) = 8 and sizeof(long) = 4.
- Improved and cleaned up implementation of signal handling.
Replay debugger:
- Improved handling of locations in source code.
OCamldoc:
- extensible {foo } syntax
- user can give .txt files on the command line, containing ocamldoc formatted
text, to be able to include bigger texts out of source files
- -o option is now used by the html generator to indicate the prefix
of generated index files (to avoid conflict when a Index module exists
on case-insensitive file systems).
Miscellaneous:
- Configuration information is installed in `ocamlc -where`/Makefile.config
and can be used by client Makefiles or shell scripts.

Objective Caml 3.08.3:
----------------------
New features:

- camlp4: install argl.* files (PR#3439)
- ocamldoc: add -man-section option
- labltk: add the "solid" relief option (PR#3343)
Bug fixes:
- typing: fix unsoundness in type declaration variance inference.
Type parameters which are constrained must now have an explicit variant
annotation, otherwise they are invariant. This is not backward
compatible, so this might break code which either uses subtyping or
uses the relaxed value restriction (i.e. was not typable before 3.07)

- camlp4: new function "make_lexer" for new-style locations
- unix: added missing #includes (PR#3088)
Objective Caml 3.08.1:
----------------------
Licence:

Objective Caml 3.08.0:
----------------------
(Changes that can break existing programs are marked with a "*" )
Language features:
- Support for immediate objects, i.e. objects defined without going
through a class. (Syntax is "object <fields and methods> end".)
Type-checking:
- When typing record construction and record patterns, can omit
the module qualification on all labels except one. I.e.
{ M.l1 = ...; l2 = ... } is interpreted as { M.l1 = ...; M.l2 = ... }
Both compilers:
- More compact compilation of classes.
- Much more efficient handling of class definitions inside functors
or local modules.
- Simpler representation for method tables. Objects can now be marshaled
between identical programs with the flag Marshal.Closures.
- Improved error messages for objects and variants.
- Improved printing of inferred module signatures (toplevel and ocamlc -i).
Recursion between type, class, class type and module definitions is now
correctly printed.
- The -pack option now accepts compiled interfaces (.cmi files) in addition
to compiled implementations (.cmo or .cmx).
* A compile-time error is signaled if an integer literal exceeds the
range of representable integers.
- Fixed code generation error for "module rec" definitions.
- The combination of options -c -o sets the name of the generated
.cmi / .cmo / .cmx files.
Bytecode compiler:
- Option -output-obj is now compatible with Dynlink and
with embedded toplevels.
Native-code compiler:
