version 0.70, July 6, 2011
==========================

  New features

  o [WhyML] language and VC generator
  o [syntax] record types
    - introduced with syntax "type t = {| a:int; b:bool |}"
      actually syntactic sugar for "type t = `mk t' (a:int) (b:bool)"
      i.e. an algebraic with one constructor and projection functions
    - a record expression is written {| a = 1; b = True |}

    - access to field a with syntax x.a
    - update with syntax {| x with b = False |}
    - record patterns

  Fixes and other changes

  * [syntax] new syntax for conjunction (/\) and disjunction (\/)
    ("and" and "or" do not exist anymore)
  * [syntax] "logic" is not a keyword anymore, use "function" and "predicate"
25 26
  o [IDE] interactive detection of provers disabled because incompatible
    with session. Detection must be done with why3config --detect-provers

  o [IDE] does not use Threads anymore, thanks to Call_provers.query_call
  o [IDE] displays explanations using labels of the form "expl:..."

  o [IDE] dropped dependence on Sqlite3
33 34 35 36 37 38 39
  o [Alt-Ergo output] bugfix: no triggers for "exists" quantifier
  o [Coq output] bugfix: polymorphic inductive predicates
  o [Coq output] fixed bug 12934: type def with several type params
  * [API] functions to create an environment are now exported from Env
  * [API] calls to prover can now be asynchronous
    Driver.prove_task now returns some intermediate value
    (of type prover_call), which can be queried in two ways:
40 41 42 43
    - blocking way with Call_provers.wait_on_call
    - non-blocking way with Call_provers.query_call
    So old code performing "prove_task t () ()" should be translated to
    "wait_on_call (prove_task t ()) ()".

  o transformation split-goal does not split under disjunction anymore
  o fixed --enable-local
  o why.conf is no more looked for in the current directory; use -C or
    WHY3CONFIG instead
  o why.conf: when changed, a backup up copy is made in why.conf.bak
  o why.conf now contains a magic number; configuration must be
    rebuilt with why3config if the magic number has changed
  o why3config: --autodetect-provers renamed to --detect-provers
                --autodetect-plugins renamed to --detect-plugins
     new option --detect to perform both detections
  o why3config: --conf_file is replaced by -C and --config

  o IDE: source file names are stored in database with paths relative

    to the database, so that databases are now easier to move from a
    machine to another (e.g when they are stored in source control
    repositories)
