5. Fixing a minor flaw in atsopt-depgen
6. Adding linset_copy in libats/linset_avltree

ats-lang-anairiats-0.2.9:
1. Fixing some macros in ccomp/runtime/ats_exception.h
2. Removing the field tmpvar_root in tmpvar and related functions.

is needed. For example, the following declarations are equivalent:
fun foo (x: int): void = "ext#"
fun foo (x: int): void = "ext#foo"
The following two are equivalent as well:
fun bar (x: int): void = "mac#"
fun bar (x: int): void = "mac#bar"

########################################################################
ats-lang-anairiats-0.2.0:
This is a milestone release. The original plan for OOP support in ATS
has been scratched completely, resulting in about 1500 lines of code being
removed. Instead, some support is added to interface ATS with external
code written in OOP-style.
The following libraries are now available for use:
contrib/glib
contrib/cairo
contrib/pango
contrib/X11
contrib/GTK
contrib/GL (OpenGL, GLU and GLUT)
contrib/SDL
Much more effort is needed to expand the APIs for these libraries. So far,
only the APT for cairo is close to completion.
########################################################################
ats-lang-anairiats-0.1.9:
(*
// this feature is retracted as it is difficult to support
1. overloaded symbols in a macro definition is re-loaded when the macro
definition is expanded. This change can greatly facilitate the use of
macros defined in $ATSHOME/prelude/macrodef.sats
2. macro expansion is now handled by [d1exp_tr] in [ats_trans2_dyn1.dats]
(instead of being done by [d2exp_tr] in [ats_trans3_dyn2.dats])
*)
3. The semantics for symbol overloading is greatly simplified.
4. Adding libc/sched based on /usr/include/sched.x
5. Adding libats/parworkshop to support multicore programming.
6. The examples in doc/EXAMPLE/MULTICORE are modified to run again.
7. Adding support for lliunt and ullint.
......
########################################################################

3. Fixing a serious mistake causing static unification variable to be
wrongly tagged.
########################################################################

1. Adding support for implementing variadic functions in ATS.
Please see the files: $ATSHOME/libc/?ATS/stdarg.?ats
2. Adding a check to detect looping caused by recursive staloading
and/or including
3. Overhauling [prelude/SATS/array.sats]
4. Adding support for special constants $FILENAME and $LOCATION.
########################################################################
ats-lang-anairiats-0.1.6:
1. Support for OOP is under development. So far, typechecking is done.
2. Type error message reporting is made more informative. This is ongoing.
3. Adding $ATSHOME/ccomp/lib64 for storing libfiles for 64-bit machines.
4. Makefiles are re-designed by Likai Liu.
########################################################################
ats-lang-anariats-0.1.5:
1. A character whose ascii code is greater than 127 is treated as the null
character by the ATS lexer. So any chars can now appear in comments.
2. Some location information is reported when a match failure occurs at
run-time.
3. [atscc] now returns a nonzero exit status to the OS if compilation does
not finish normally.
4. various list functions (e.g., list_map_* functions) now return linear
lists instead of nonlinear ones.
5. Some packages in SML Basis Library are implemented in [libats/smlbas]
6. A bug is fixed that was due to nonlinear constructor patterns being
given reference arguments.
7. The constant [div_int_int_int_bool] is re-defined as the previous
definition was wrong if the divider and the dividee are of different
signs.
8. A bug is fixed that was duo to [as] patterns being wrongly compiled.
9. [prelude/SATS/matrix0.sats] and [prelude/DATS/matrix0.dats] are added.
########################################################################
ats-lang-anariats-0.1.4:
1. [atscc] invokes a C compiler to compile the C code generated by the ATS
compiler [atsopt]. If the C compiler to be used is not [gcc], please set
the environment variable [ATSCCOMP] to the name of this C compiler.
########################################################################
ats-lang-anariats-0.1.3:
1. Various bug fixes. In particular, a bug causing incorrect compilation
of pattern matching is fixed.
2. It is now possible to generate html files for cross-referencing. The
flag for this feature is [--posmark_xref=XREF], where XREF should be
replaced with the name of some directory (already created) to store
the html files to be generated.
########################################################################
ats-lang-anariats-0.1.2:
1. Linear lazy evaluation is now supported. See [prelude/DATS/file.dats]
for some code using this cool feature.
2. Many new tutorials have been added. There is also a all-in-one format
that allows for easy printout.

[doc/EXAMPLE/KernighanRitchie].
########################################################################
ats-lang-anariats-0.1.1:

on the interpretation of the C compiler used to compile the C code that
is generated from ATS programs by [atsopt].
2. [scase] is now supported.
3. [x1,x2:int] <pat> is now a legal pattern; it is equivalent to the following
pattern [x1:int,x2:int] <pat>
4. It is now allowed in ATS to allocate (linear) arrays on stack at run-time.
########################################################################
ats-lang-anariats-0.1.0:
1. The syntax for template implementation is changed:
previous syntax: implement foo<a,b><c> (...) = ...
current syntax: implement{a,b}{c} foo (...) = ...
2. It is now allowed to implement a special template instantiation:
implement foo<double,string><int> (...) = ...
3. Various bug fixes can be found in BUGS.txt.
########################################################################

1. fixed a bug affecting [nonfix] declarations.
2. [ats_trans1.dats] is splitted into the following two:
[ats_trans1_sat.dats] and [ats_trans1_dyn.dats]
3. Make/Install is significantly improved. There is no need to set
ATSHOME (and ATSHOMERELOC) before 'make all' is executed.
4. The confusion between array and array0 is resolved.
5. [EXAMPLE/SHOOTOUT/SUMBIT] is created.
6. The function [intvec_normalize_gte] did not handle the case [gcd > 1]
correctly. It is fixed now.
7. The incorrect handling of [continue] in a for loop is fixed now. See
[BUGS.txt]
8. The command [atspackage] no longer puts the source code for Anairiats
into a distribution.
