The following are the changes in this release:
Updated COPYING file to indicate that these files are now
covered under "The Unlicense" (see https://unlicense.org):
sha1.c
sha1.h
cal/dotest.cal
cal/screen.cal
Updated help/credit to match the above changes to COPYING.

for contributing to calc (instead of using Email).
Updated BUGS and calc.man to refer to using GitHub issues
for reporting calc bugs (instead of using Email).
Updated QUESTIONS and calc.man to refer to using GitHub issues
for asking calc questions (instead of using Email).
Fixed Makefile.local command example to refer to overriding the
Makefile variable DEBUG (instead of CDEBUG).

with the following uncommented lines in Makefile.local:
DEBUG:= -O0 -g
CFLAGS+= -fsanitize=address -fno-omit-frame-pointer -fsanitize=undefined
LDFLAGS+= -fsanitize=address -fno-omit-frame-pointer -fsanitize=undefined
CALC_ENV+= ASAN_OPTIONS=detect_stack_use_after_return=1
Improved how pointers to functions are declared for the builtins
array in func.c to avoid function declarations without a prototype
that is now deprecated in C.
Improved how pointers to functions are declared for the opcodes
array in opcodes.c to avoid function declarations without a prototype
Replaced use of egrep with grep -E in Makefiles.
Fixed cases where variables were set but not used in symbol.c, calc.c,
and the main function in func.c as used by funclist.c.
Added rule name to "DO NOT EDIT -- generated by the Makefile" lines
in constructed files.
Test if <sys/vfs.h> exists and set HAVE_SYS_VFS_H accordingly
in have_sys_vfs.h. Added HAVE_SYS_VFS_H to allow one to force
this value.

The following are the changes in this release:
Fixed missing <string.h include in have_fpos_pos.c.
Change calc version from 2.14.1.2 to 2.14.2.3 as part of a test to
build calc RPMs on a reference RHEL8.7 platform (formerly a RHEL7.9
platform).
Otherwise, the probe result changes with compilers which do not
support implicit function declarations, a language feature that
was removed from C in 1999.
Added config("fraction_space", boolean) to help/config, along with
a few few minor text improvements. Updated cal/regress to test
config("tilde_space").
Added config("complex_space", boolean). The "complex_space" controls
whether or not a space (' ') is printed before and after the + or -
in complex values.
By default, config("complex_space") is false.
For example, with the default, config("complex_space", 0):
; asin(2)
1.57079632679489661923-1.31695789692481670863i
With config("complex_space", 1):
; asin(2)
1.57079632679489661923 - 1.31695789692481670863i
NOTE: Use of config("complex_space", 1) can break printing and scanning
of fractional values via "%r".
NOTE: Use of config("complex_space", 1) can break printing and scanning
of complex values via "%c".
Added config("complex_space", boolean) to help/config, along with
a few few minor text improvements. Updated cal/regress to test
config("complex_space").
Clarify in the calc man page, the relationship between -q and
calc start scripts such as the ~/.calcrc file.
Fixed in the calc man page, the issue of -f not implying -q.
Added config("tilde_space", boolean) to help/config, along with
a few few minor text improvements. Updated cal/regress to test
config("tilde_space").
Added config("fraction_space", boolean). The "fraction_space" controls
whether or not a space (' ') is printed before and after fractions.
By default, config("fraction_space") is false.
For example, with the default, config("fraction_space", 0):
; base(1/3),
; 1/7
1/7
With config("fraction_space", 1):
; base(1/3),
; 1/7
1 / 7
NOTE: Use of config("fraction_space", 1) can break printing and scanning
of fractional values via "%r".
NOTE: Use of config("fraction_space", 1) can break printing and scanning
of complex values via "%c".
Added config("fraction_space", boolean) to help/config, along with
a few few minor text improvements. Updated cal/regress to test
config("tilde_space").
Added config("tilde_space", boolean). The "tilde_space" controls
whether or not a space (' ') is printed after leading tilde ('~').
By default, config("tilde_space") is true, which is a change
from past behavior. For example, now:
; 1/3
~ 0.33333333333333333333
With config("tilde_space", 0):
; 1/3
~0.33333333333333333333
To disable "tilde_space", use config("tilde_space", 0) on the
command line and/or use config("tilde_space", 0),; in your ~/.calcrc.
Thanks goes to <GitHub use ljramalho> for this suggestion.
Added config("tilde_space", boolean) to help/config, along with
a few few minor text improvements. Updated cal/regress to test
config("tilde_space") and to account for the new default.
In pseudo_seed(), we removed a call to setjmp() that was only
there to add more information to mix into the seed. For compilers
such as gcc that used -Wclobbered, the call to setjmp() gave the
impression that the hash_val might be clobbered by a longjmp().
Where there is no longjmp() that would use the previous setjmp(),
the gcc compiler has nil ways to notice that. So to avoid confusion
we removed the setjmp() call. Thanks to <GitHub user mattdm> for
raising this potential concern.
In find_tty_state(), we changed how we expand fd_orig as an original
pre-modified copy of fd_setup. We realloc the fd_orig array and copy
the fd_setup into it first, before touching the fd_setup array.
Fixed a -Wuse-after-free warning that identified a call to realloc() in
find_tty_state() could move the fd_setup array. Thanks goes to <GitHub
user mattdm> for reporting this bug!
The following are the changes in this release:
Restored use of the #define FPOS_POS_LEN symbol. This refers to
the length of the __pos element (if the __pos element exists),
the fpos_t type (if that type exists).
Changed SWAP_HALF_IN_FILEPOS(dest, src) mato to use FILEPOS_LEN Little
Endian when FILEPOS is a simple scalar type (i.e., HAVE_FILEPOS_SCALAR
is defined).
Changed #define HAVE_FPOS to HAVE_FGETSETPOS.
Corrected comment in have_fpos_pos.h. The HAVE_FPOS_POS symbol was
NOT related to fgetpos & fsetpos but rather if we we have an __pos
element in FILEPOS.
Changed #define HAVE_NO_FPOS to HAVE_NO_FGETSETPOS.
Improved comments in have_fpos_pos.h to show why and how
HAVE_FPOS_POS, FPOS_POS_BITS, and FPOS_POS_LEN were defined or undefed.
Changed showfiles builtin to print sizes cast to (long int) with
the "%ld" printf format to avoid implementations that do not support
the "%lld" printf format specifier.
Renamed have_fpos.h to have_fgetsetpos.h. Renamed CALC_HAVE_FPOS_H
to CALC_HAVE_FGETSETPOS_H. The make install and the olduninstall
rules remove the any old have_fpos.h that was previously installed.
Added swap_HALFs(dest, src, len) function to byteswap.c.
Calc can now handle Big Engian file position sizes that are a
multiple of BASEB bits in length. Before handle Big Engian file
positions could only be 32 and 64 bits in length. This will allow,
for example, a Big Engian file position size of 128 (assuming that
128/BASEB is is an integer).
Temporary workaround for musl libc systems such as gentoo Linux that
allows them to compile calc and successfully run the regression test.
Restored use of the #define FPOS_POS_LEN symbol. This refers to
the length of the __pos element (if the __pos element exists),
the fpos_t type (if that type exists).
Changed SWAP_HALF_IN_FILEPOS(dest, src) mato to use FILEPOS_LEN Little

Added full_debug rule to Makefile. This does the work of the
old debug rule in a more verbose mode by using Q= H=@ S= E= V=@.
The debug rule in the Makefile now pre-removes debug.out and then
runs make full_debug sending stdout and stderr to debug.out. It then
prints a few instructions about filing a GitHub issue bug report.
The following are the changes in this release:
Added a few remarks on calc version numbers to version.c.

file failed to compile incorrectly. This caused problems for systems in
which fposval.h.def was not correct.

file failed to compile incorrectly, producing a potentially incorrect
have_memmv.h file for such systems.

file failed to compile incorrectly, producing a potentially incorrect
align32.h file for such systems.

failed to compile incorrectly, producing a potentially incorrect
have_newstr.h file for such systems.
