Transformations
  * All split transformations respect the "stop_split" label now.
    split_*_wp is a synonym for split_*_right
  * split_*_right split the left-hand side subformulas
    when they carry the "case_split" label
  * split_intro is now the composition of split_goal_right and
    introduce_premises

    (BTS #17181)

transformations
  * fix a soundness bug in "compute_in_goal" regarding the handling of
    logical implication.
  o several improvements to "compute_in_goal":
    . left-hand side of rewrite rules can be any symbols, not only
      non-interpreted ones.
140 141
    . perform beta-reduction when possible

    subcommands: execute, extract, and realize
  * why3replayer has been moved to the "replay" subcommand
  * other tools have been moved to why3 subcommands too: config, doc, ide,
    session, wc; for local usage, the old commands are still available

proof sessions
  o session files are split in two parts: "why3session.xml" and
    "why3shapes". The latter file contains the checksums and the shapes
    for the goals. That second file is not strictly needed for
    replaying a proof session, it is only useful when input programs
    are modified, to track obsolete goals. If Why3 is compiled with
    compression support (provided by ocamlzip library) then files for
    shapes are compressed into why3shapes.gz.

174 175 176
library
  * renamed array.ArraySorted -> array.IntArraySorted
    array.ArraySorted is now generic, with type and order relation parameters

177 178 179 180
  * reduced amount of "use export" in the standard library: theories
    now only export the symbols they define. Users may need to insert more
    "use import" in their theories (typically int.Int, option.Option,
    list.List, etc.).

version 0.83, March 14, 2014
============================

syntax
  o extra semicolons are now allowed at end of blocks
  o new clause "diverges". Loops and recursive calls not annotated
    with variants will generate a warning, unless the "diverges"
    clause is given
  o clauses "reads" and "writes" now accept an empty set
  * modified syntax for "abstract": abstract <spec> <expr> end
204 205
  o types in quantifiers are now optional
  o formulas and Boolean terms can be used interchangeably
206 207

  o [logic] accept type expressions in clone substitutions
  o [whyml] support for relation chains (e.g., "e1 = e2 < e3")
  * [whyml] every exception raised in a function must be listed
    in as "raises { ... }" clause. A postcondition may be omitted
    and equals to "true" by default.
  * [whyml] if a function definition contains a "writes { ... }"
    clause, then every write effect must be listed. If a function
    definition contains a "reads { ... }" clause, then every read
    _and_ write effect must be listed.
  * [drivers] syntax rules, metas, and preludes are inherited
    through cloning. Keyword "cloned" becomes unnecessary and
    is not accepted anymore.

==========================

  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 |}

  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:
419 420 421 422
    - 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)
