  SmallEiffel/man/external.hlp).

- Release - 0.93 -  Thursday July 18 1996
  * Fixed some more bugs with conformance rule VNCG.
  * Type BIT is now implemented.
  * Added ELKS 95 `STRING.left_adjust' and `STRING.right_adjust'.

- Release - 0.92 -  Saturday July 20 1996
  * Fixed some more bugs with conformance rule VNCG.
  * Added Maths function in DOUBLE/REAL (sin, cos, tan, asin,
  acos, atan, ... ANSI C names).

- Release - 0.91 -  Wednesday July 24 1996
  * Incremental C compiling mode implemented (see option -c_code
  in man/compile.hlp).
  * Added command `clean' (see man/clean.hlp).
  * Added class FILE_TOOLS.
  * No more empty C struct in generated C code (to avoid problems
  with Microsoft Windows C compiler).
  * Fixed one more bug with conformance rule VNCG.

- Release - 0.90 -  Friday August 23 1996
  * Added random number generator library (SmallEiffel/lib_rand).
  * Added checking of assertions for external "CSE" features.
  * Anchoring on expanded types are now allowed.
  * Multiple level of anchoring definition allowed.
  * Fixed a bug in STRING.from_external.
  * Fixed a bug with mixed rename/redefine.
  * Inheritance loop detection.
  * Anchoring loop detection.
  * Fixed a bug with renaming infix/prefix.
  * Command `clean' also use the make suffix.
  * Added ELKS95 `sign' in INTEGER/REAL/DOUBLE.
  * Feature `make' is the default root feature name for `compile'.
  * Optimized ARRAY.add_last and STRING.extend.
  * Changed STRING.out (no more enclosing %" printed).
  * Remove warning gcc messages for 64 bits machine (alpha/DECK).
  * Added option -no_split for a better finalization (see
  compile_to_c.hlp).

- Release - 0.89 -  Sunday September 15 1996
  * Calling Eiffel from C is now implemented (see cecil.hlp).
  * Object creation uses C `calloc' instead 'malloc'+`memset'.
  * Object creation is inlined.
  * ARRAY/FIXED_ARRAY `put' and `item' are now inlined (-boost only).
  * Added feature `capacity' and `resize' in FIXED_ARRAY.
  * Added some classes in std_lib: LINK2_LIST (two way linked
  list), COLLECTION2 (deferred), ARRAYED_COLLECTION (deferred),
  LINKED_COLLECTION (deferred) and FIXED_ARRAY2 in std_lib.
  * More user's routines are inlined (-boost only).

- Release - 0.88 -  Wednesday October 30 1996
  * Fixed bugs dealing with inherit/rename/select.
  * Added warning for missing colon in actual arguments list.
  * Warning : INSTALL procedure has changed and you have to set
  manually the default loading path (see misc/INSTALL for details).
  * Added some VMS customisation.
  * Fixed bugs when printing run-time stack.
  * Warning added for missing colon in actual parameter list.
  * Added `flush' in STD_FILE_WRITE.
  * No more left hand side cast in C code.

- Release - 0.87 -  Tuesday January 7 1997
  * Added a new flag "-trace" to ease debug (see compile_to_c.hlp).
  * More inlining at Eiffel level (-boost mode only).
  * Class BIT_N completely revisited. It may be as fast as C.
  * Added class C_ARRAY[E] to deal directly with C arrays at Eiffel
  level. Thus there are no more external "CSE" or c_inline_c in
  classes STRING/ARRAY/FIXED_ARRAY (only full Eiffel).
  Eiffel code is nice and STRING/ARRAY/FIXED_ARRAY may run faster.
  * Fixed a bug in STD_FILE_READ.read_double.
  * Ordering of C output to increase gcc inlining.
  * According to compile_to_c.hlp, -debug_check now works (debug
  instructions are no longuer generated in mode -all_check).
  * Unused local variables removed at Eiffel level (warning added
  for -debug_check mode only).
  * Default class ANY now inherit PLATFORM (as in ETL).
  * Fixed a bug in floating-point constants.
  * Added directory `sys' to customize default C compiler, default
  C linker and default loading path.
  * Fixed some bugs with outside expanded types.
  * Fixed a bug with rename/select.
  * Redefinition of once routine is now allowed.
  * Feature GENERAL.conforms_to is now implemented.
  * Rule VFFD.7 is now enforced.
  * Feature `force' implemented for all COLLECTION.
  * Added conversions features CHARACTER.to_bit, INTEGER.to_bit,
    BIT_N.to_character and BIT_N.to_integer.

- Release - 0.86 -  Sunday April 13 1997
  * All reported bugs at this time are fixed.
  * Added flag -verbose to commands `compile', `compile_to_c' and
  `clean'. When this new flag is not present, commands now works silently
  unless some error (or warning) occurs.
  * Features BOOLEAN.infix"or" and BOOLEAN.infix"and" are now written in
  pure Eiffel. As a consequence, it is very important for the SmallEiffel
  programmer to make the distinction between BOOLEAN.infix"and then" and
  BOOLEAN.infix"and" (respectively for BOOLEAN.infix"or else" and
  BOOLEAN.infix"or"). When LHS argument produce no side effects, the
  semi-strict operator (BOOLEAN.infix"and" and BOOLEAN.infix"or") may run
  faster.
  * Fixed REAL.sin (was calling sqrt :-).
  * Fixed a bug in INTEGER.append_in (you can now print Minimum_integer).
  * Added feature COMPARABLE.in_range.
  * Result type of REAL.infix "^" is now DOUBLE for ELKS compatibility.
  * Feature `remove' is now implemented in all subclasses of COLLECTION
  (i.e. ARRAY, FIXED_ARRAY, LINK_LIST and LINK2_LIST).
  * Added feature `add' for all subclasses of COLLECTION.
  * Conversion DOUBLE/STRING : ANSI C `sscanf' and `sprintf' is now used
  to avoid loss of precision.
  * Added some more class invariant code generation when compiling in
  -invariant_check mode. Class invariant is now check before exit of a
  routine.
  * Added feature `file_tools' in class GENERAL to ease access to class
  FILE_TOOLS.
  * Changed printing format for basic *_REF classes. For example,
  instruction `print(1);' now print 1.
  * DOUBLE.truncated_to_integer is now ELKS compatible (added DOUBLE.rounded
  to replace the old DOUBLE.truncated_to_integer). Same change in class
  REAL.

--- WORK IN PROGRESS (current priority list) --- :
  * Command `compile_to_jvm' to produce Java Byte Code from Eiffel.
  * Command `short' to produce short and flat-short.
  * Command `check_up' to check system validity rules.
