Open Source Release Magnesium-20151002
######################################

o! Kernel     [2016/01/03] Modules Dataflow is deprecated, and will be removed
              in Aluminium. Module Dataflow2 offers a very similar but simpler
              API.
-  Doc        [2015/11/16] Fixed typo in the manual (Thx Mihaela Sighireanu)
-* Kernel     [2015/10/12] Fix clearing of old statuses and hypotheses when a
              new status is emitted or an annotation is removed.
-! Kernel     [2015/09/07] Removed support for OCaml 3.12.1
-  Value      [2015/09/03] Assertions containing \at(P, L), where L is a C
              label, can now be evaluated. Evaluation is done once Value has
               run; thus, it ignores option -slevel
-* Value      [2015/09/03] pointer_comparable alarms are now emitted with
              arguments properly cast to void* or void (*)()
-  Value      [2015/08/10] The alarms raised when evaluating a global
              initializer that leads to an undefined behavior are now marked
              with an "Invalid" status
-  Report     [2015/08/10] Reports in csv format now honor option
              -report-specialized (previously, preconditions at a
              callsite were always skipped)
-* Libc       [2015/08/26] Fix bug in the specifications of readir, opendir,
              closedir and fopen functions, that would cause incorrect analysis
              in -lib-entry-mode
-! Value      [2015/08/03] WIDEN_HINTS directive are now cumulative with
              automatically inferred bounds. Fixes bug #876
-* Cil        [2015/08/03] Fix bug #1553, related to nested initialisations
              of structures containing pointers
-! Value      [2015/08/03] All plugins that depend on Value, plus Value itself
              are now dynamic. Custom plugins must specify in their Makefile the
              plugins they depend on (e.g. PLUGIN_DEPENDENCIES:=Inout Value)
-* Cil        [2015/07/29] Cil transformation can introduce assertion to ensure
	      that size expressions in an array declarations evaluated at
	      program execution time are positive and do not overflow.
o  Ptests     [2015/07/29] New LOG: directive
-  Value      [2015/07/19] Garbled mix origins now include at most one source
	      location
-  Report     [2015/07/19] New option -report-proven to control the display
	      of proven properties
-  Report     [2015/07/19] New export format (.csv), through option -report-csv
o! Callgraph  [2015/07/16] Remove Cil.Callgraph, Db.Syntactic_callgraph and 
              Db.Semantic_callgraph which are all replaced by the single
              plug-in Callgraph. See Changelog_detailled.md for further detail
              about this change.
-! Callgraph  [2015/07/16] New plug-in callgraph which merges the old
	      Syntactic_callgraph and Semantic_callgraph plug-ins (now
	      removed). Either this plug-in uses Value if already computed, or
	      computes the syntactic callgraph otherwise. This new plug-in
	      unifies the behavior of its two ancestors. In particular,
	      the edges of callgraph computed with the help of Value are
	      now directed in the same way as the syntactic callgraph (was
	      reversed before) and so the computed services are now
	      equivalent. Also, the uncalled functions are now displayed
	      by default. For plug-in developers, the callgraph is easily
	      accessible via an API (bts #755).
-! Value      [2015/07/14] Float operations that are guaranteed to lead
	      to +/-infty (e.g. x = FLT_MAX*10.) now stop propagation.
              Previous behavior was to continue with an imprecise value for x.
-  Kernel     [2015-07-09] New option -custom-char-annot for changing the
              character introducing ACSL annotations (instead of '@')
-  Value      [2015/07/09] Do not emit pointer_comparable alarms on valid
	      pointer comparisons involving objects of size 0
-  Value      [2015/07/07] The semantics of copying a lvalue has been changed
	      when a type mismatch occurs between the destination and the copied
	      value. A bitwise reinterpretation of the value to the destination
	      type is now performed during the copy.
o! Kernel     [2015/07/01] Ival.Float_abstract renamed to Fval.
	      Fval.inject_r now may raise Fval.Non_finite instead of the old
	      Float_abstract.Bottom.
-  Value      [2015/06/29] Option -val-split-return-auto now always split
	      between NULL/non-NULL pointers
-* Value      [2015/06/26] Check the validity of the operands of the ACSL
	      operators /, %, << and >> when evaluating a predicate
o! Value      [2015/06/25] Remove duplicate values Ival.singleton_zero and
	      Ival.singleton_one. Use script sodium2magnesium.sh for automatic
	      migration
-*  Logic     [2015/06/15] Fix typing bug when converting into a term an
	      expression containing a pointer substraction
-* Value      [2015/06/09] Pointer comparisons using relational operators (<,
	      >=, etc) between a pointer and NULL is now flagged as undefined.
o! Kernel     [2015/06/09] Remove support of plug-ins without .mli.
-*  Cil       [2015/05/29] Better typing of '?' operator. Fixes bug #2117.
o! Kernel     [2015/05/29] Remove long-obsoleted functions Cfg.computeCFGInfo
	      Cfg.printCfgFilename, and Cfg.printCfgChannel
-  Value      [2015/05/28] Functions call using a function pointer are now
	      treated more leniently when too many arguments are supplied. An
	      alarm is emitted, but execution continues with the right number
	      of arguments.
-  Value      [2015/05/12] Improved reduction by predicate \initialized when
	      the left argument is a range of locations
-  Impact     [2015/05/12] Removed function Db.Impact.slice, that was actually
	      unrelated to Impact. You can use the functions contained in
	      Db.Slicing.Select, in particular Db.Slicing.Select.select_stmt,
	      to obtain the same result.
-  Makefile   [2015/05/06] Dynamic plug-ins are now declared as Findlib
   	      packages. Use variables PLUGIN_REQUIRES and PLUGIN_DEPENDENCIES.
	      Loading a plug-in automatically loads all necessary dependencies.
	      Plugin "MyPlugin" is register under "frama-c-myplugin" package.
-! Kernel     [2015/05/06] Dynamic now rely on Findlib. Small changes in API.
   	      Option -load-module can now load any Findlib package and its
	      dependencies as well.
-  Kernel     [2015/05/06] Reformulated help messages.
	      Option -help is more concise.
	      Option -version only prints version number.
              Options -print-xxx uniformized.
	      New options -plugins, -print-config.
-   Value     [2015/05/29] Added built-ins for mathematical functions: atan2,
	      fmod, pow, expf, logf, log10f, powf, sqrtf, floor, floorf,
	      ceil, ceilf, round, roundf, trunc, truncf.
-*  Value     [2015/05/03] In -lib-entry mode, allow the generation of initial
	      states with 0-sized bitfields
-* Metrics    [2015/05/05] Fix computation of global cyclomatic complexity.
	      Fixes bug #!2089.
-   Scope     [2015/04/22] Assertions previously removed by
	      -remove-redundant-alarms are now marked as proven, but remain in
	      the AST
-   Value     [2015/04/22] New GUI panel 'Values', that displays nearly all the
	      information previously available under the 'Information' panel
o!  Logic     [2015/04/08] Functions Db.Properties.Interp.lval and
	      Db.Properties.Interp.expr have been renamed (into term_lval
	      and term, respectively), and have a new signature
-* Cil        [2015/04/19] Fix parsing of packing directives of the form
	      '#pragma pack(push, N)'
-! Value      [2015/04/13] In -lib-entry mode, functions pointers no longer
	      force the generation of dummy functions. Instead, they are
	      initialized to NULL. Fixes bug #!2104.
-  Kernel     [2015/04/01] New API for backward dataflow propagation in file
	      Dataflows
-  Metrics    [2015/03/25] New category 'Extern global variables', that can
	      be used to check whether some files are missing
-  Metrics    [2015/03/24] Functions from Frama-C standard library are now
	      hidden by default
-* Cil	      [2015/03/26] Switch statements in which some cases are not
	      constant expressions are now completely disallowed, as per the
	      C standard.
-! Cil        [2015/03/21] Parsing no longer accepts structures containing
	      incomplete types. Fixes bug #!2091
-  Kernel     [2015/03/24] Special functions CEA_ have been removed
-! Libc       [2015/03/19] Most .c and .h files under /share have been merged
              into /share/libc. Inclusions of builtin.h should be replaced by
              __fc_builtin.h
-  Kernel     [2015/03/18] New ACSL predicate \valid_read_string in
	      share/libc/__fc_string_axiomatic.h
-! Value      [2015/03/12] Terms involving l-values that are bit-fields are now
	      correctly handled
-  Cil        [2015/03/19] Fix incorrect simplifications of '!E' to 0 when
	      E is either an enum with value 0 (bug #2090), or an expression
	      whose value wraps.
-  Kernel     [2015/03/10] macro __FRAMAC__ is defined when pre-processing
	      C files in Frama-C
o! Kernel     [2015/03/10] AST change: split GVarDecl into GVarDecl and GFunDecl
o!  GUI       [2015/04/04] Constructor Pretty_source.PTermLval now has an
	      additional argument, the property in which the term appears
-   Defs      [2015/04/04] L-values for which defs are queried are now evaluated
	      only for the callstacks that are currently active, resulting
	      in possibly less locations
-!  Value     [2015/03/08] Fix bug in -memexec-all option in presence of
	      instructions where evaluation was guaranteed to fail
-! Inout      [2015/03/08] The inputs of an instruction whose evaluation always
	      fail include the sub-expressions for which evaluation succeeds
-  Kernel     [2015/02/26] Added -no-tty option to disable terminal capabilities
-  Value      [2015/02/23] Faster treatment of imprecise struct copying and
	      left shifts in the logic
o! Kernel     [2015/02/22] Function Integer.two_power now raises an exception
	      for overly big arguments
-  Kernel     [2015/02/20] Add new suffix '.ci' for pre-processed files
              containing ACSL annotations to be pre-processed
-! Value      [2015/02/18] In synthetic results, for local variables that are
	      not those of the current function, the approximated values
	      encompass only the callstacks for which the variables were
	      in scope in one of the callers
-  Value      [2015/02/18] Local variables that are in scope but not yet
	      initialized are now present in the environment
-! Value      [2015/02/15] Option -subdivide-float-var has been renamed into
	      -val-subdivide-non-linear, and has now an effect on non-linear
	      integer expressions
o! Value      [2015/02/15] Removed function Cvalue.V.min_and_max_float. Use
	      Cvalue.V.project_ival and Ival.min_and_max_float
-  Cil        [2015/02/11] Function Printer.change_printer now allows composing
	      printers, and is called Printer.update_printer
-  GUI        [2015/02/11] Variables are now left- and right- clickable in
	      the 'information' panel.

-* Logic      [2015/02/09] The ACSL parser accepts qualifiers in logic C types.
-  Value      [2015/01/07] Special functions CEA_ are deprecated. Use
	      Frama_C_show_each or Frama_C_dump_each instead.
-  Kernel     [2014/12/28] Improve pretty-printing of some loops.
-* Kernel     [2014/12/16] -load-module M now works fine if M uses the API
	      of another plug-in (bts #!1824).
-! Cil        [2014/12/09] Default preprocessing command now includes Frama-C's
	      standard library, and when possible sets option '-nostdinc'.
	      See options -frama-c-stdlib and -cpp-gnu-like.
*! Cil        [2014/12/09] Variables __FC_MACHDEP_FOO_BAR are now automatically
	      positioned when setting a non-standard machdep and using Frama-C's
	      standard library.
-  Cil        [2014/12/09] Option -pp-annot should be much faster when parsing
	      files with many ACSL annotations.
-  Logic      [2014/11/28] The ACSL parser now ignores /*@{ and /*@} comments,
	      to avoid conflicting with Doxygen.
-  Value      [2014/11/10] Accesses to locations that contain garbled mix now
	      cause the garbled mix to be reduced to the set of valid locations.
-  Value      [2014/11/07] Accesses to '*(foo *)p' may now reduce p according
	      to the validity of the access, when useful.
-  Value      [2014/11/07] Removed message "assigning non-deterministic
	      value from the first time".
-  Value      [2014/10/28] Option -slevel-merge-after-loop renamed to
	      -val-slevel-merge-after-loop. Now takes a set of kernel functions
	      as an argument.
-  Value      [2014/10/24] Per-callstack results are now always computed.
	      Option -val-callstack-results is deprecated.
-  From       [2014/10/24] New option -from-verify-assigns to give assigns/from
	      clauses of function with bodies a validity status.
-! Value      [2014/10/24] Logic ranges are now evaluated using a dedicated
	      lattice. Results are almost always more precise, and the analysis
	      faster.
-* Kernel     [2014/10/23] allow dynamically loaded module to start with a
	      lower-case letter. Fixes #1276.

	      the source location.
-  Value      [2014/10/15] Arguments of functions that give rise to an alarm
	      are now reduced when possible.

o! Value      [2014/09/26] Remove experimental support for periodic bases.
-* Value      [2014/09/25] Fix bug when writing precise values at too many
	      locations in packed arrays.
-* Value      [2014/09/19] When for missing '\from' clause for '\result' when
	      result is used in a postcondition. Fixes bug #1908.
o! Value      [2014/08/29] Garbled mix (constructor Top in modules
	      Location_Bits/Bytes) now explicitly mention the NULL base.
-  Kernel     [2014/08/15] New option '-then-last', which behaves like
	      '-then-on' on the last project created by a program transformer.
-* Value      [2014/07/27] Text-only alarms that used the '\defined' predicate
	      (to warn about dereferencing pointers to out-of-scope variables)
	      are now emitted with the '\dangling_contents predicate.
-  Logic      [2014/07/27] The ACSL predicate '\specified', which has been
	      renamed to '!\dangling_contents' is now supported.
o! Value      [2014/07/22] Value 'empty' is no longer exported in module
	      Offsetmap. The API should prevent any accidental creation.
-  Inout      [2014/07/22] Remove undocumented option -access-path
o! Value      [2014/07/22] Most iterators of module Lmap and Cvalue.Model
	      now accept only the non-bottom and non-top cases.
o! Value      [2014/07/22] API of module Cvalue.V_Or_Uninitialized is now
	      type-safe. Replace all occurrences of 'get_flags v' by 'v'.
o! Value      [2014/07/22] Improve and clarify the return conventions of modules
	      Offsetmap, Lmap, Cvalue.V_Offsetmap and Cvalue.Model, by returning
	      three cases: `Bottom, `Top and `Map. The latter case indicates
	      the operation succeeded precisely'.
o! Value      [2014/07/22] Functions find_base and find_base_or_default in
	      modules Lmap and Cvalue.Model now return an optional type, to
	      account for invalid bases (that may not be present in the map).
o! Value      [2014/07/22] Some functions of modules Offsetmap, Lmap,
	      Cvalue.V_Offsetmap and Cvalue.Model now require a separate
	      Locations.Location_Bits.t and (integer) size, instead of a
	      Locations.location. This avoids errors when the case was
	      Int_Base.Top.
o  Value      [2014/07/22] Argument ~conflate_bottom to Cvalue.Model.find is now
	      optional. The documentation has been updated to better explain its
	      meaning.
-  Value      [2014/07/22] Message 'extracting bits of a pointer' is no longer
	      emitted, as it was redundant with the warnings about garbled mix.
-* Value      [2014/07/22] Fix evaluation of '/' in the logic, that silently
	      ignored the presence of the value 0 in the divisor.
-  Value      [2014/07/22] The arguments of an invalid shift operation are now
	      reduced so that they belong to the proper range.
o! Value      [2014/07/22] Multiple low-level functions have been removed from
	      modules Cvalue.V and Cvalue.Model, and are no longer available.
o! Value      [2014/07/22] Function Cvalue.Model.find does *not* signal its
	      result is indeterminate anymore. Use function
	      Cvalue.Model.find_unspecified instead.
o! Value      [2014/07/22] Major API change in directories src/ai and
	      src/memory_state. Functions no longer take ~with_alarms arguments.
	      Instead, they return booleans, that indicate an alarm occurred.
-  Value      [2014/07/22] More systematic emission of message 'operation [...]
	      incurs a loss of precision', signaling an arithmetic operation
	      on a pointer address. This message is now emitted by Value itself.
-! Kernel     [2014/07/09] New way to handle command line options which
	      accepts sets of values. Values may be prefixed by '+' or
	      '-' to add/remove them and categories of values prefixed by

	      now displays a callstacks-wide consolidation of the possibles
	      values for expressions and terms. Previously, the potentially
	      less precise summary state was used.
-  From       [2014/04/05] Major performance improvements on big analyses.
-! Value      [2014/04/05] Complete rewrite of the modules Int_Intervals and
	      Offsetmap_bitwise; both are now implemented with the same
	      datastructure as Offsetmap. Many performance improvements.
	      Many changes in the API of module Offsetmap_bitwise. Few changes
	      in Int_Intervals, but the englobing module Lattice_Interval_Set

	      requires the address to be comparable to NULL.
-  Value      [2014/03/02] Alarms are now re-evaluated at the end of the
	      analysis. If their truth value is 'Valid' or 'Invalid', this more
	      precise status is used, instead of the previous 'Unknown' one.
-  Value      [2014/03/01] Preconditions of functions that are never called are
	      now also marked as dead at each call-site.
-  Rte        [2014/03/01] Very big floating-point constants that are converted
