Merlin 2.1.0

backend:

• add PPX support
• make use of context before locating (#308, #316, #318).
• generate match patterns for arbitrary expressions and missing patterns for incomplete matchings (#123).
• reintroduce type expansion (asking the times of the same expression several times will resolve type aliases).
• "smart" (a.k.a "do what I mean") completion: L.m will expand to List.map ; List.m... ; ListLabels.map ; ... if L doesn't exist.
• simplify incremental parser and typer interfaces
• locate: better handling of packed modules (supposedly)
• more precise recovery on patterns (before the recovery was done at the expression level, so the whole match was discarded, now only the pattern is)

emacs:

• don't use fringe in emacs23 (broken)
• remove obsolete aliases: merlin-occurences => merlin-occurrences merlin-to-end => merlin-error-check
• disable merlin-mode on type buffer
• require caml-types (needed for highlighting) (#331).

misc:

• update README (#301).

vim:

• add a type history buffer (#313, #322) -- only available for vim > 7.3.
• highlight types when displaying them in the command line -- only for vim > 7.3
• add tab completion for the argument of the :Locate command
• add support for text objects based on type enclosing
• introduce an interactive version of :Rename
• locate results can now be shown in a new or existing tab (#335)
• use fileencoding where necessary (#332)
• ctrlp bindings for outline and locate
