* Bug fixes
* New features:
- otherlibs/labltk: browser uses menu bars instead of menu buttons
Changes 3.09.0:
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.
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.
* Other (see 'Changes')
