followed by digit (ignore 2nd byte of FNC4 when categorizing
Code C characters)
- New `ZBarcode_Cap()` flag `ZINT_CAP_BINDABLE`, differentiated
from `ZINT_CAP_STACKABLE`, and new Qt Backend method
`isBindable()`
- CLI: fix `separator` check to use new `ZINT_CAP_BINDABLE` instead
of `ZINT_CAP_STACKABLE`
- ZBarcode_Cap: add missing symbologies to `ZINT_CAP_BINDABLE` (was
`ZINT_CAP_STACKABLE`)
- DOTCODE: pad rows if given number of columns instead of failing
if rows below min (5)
- DBAR/composites: ensure stacked symbologies and composites are
not stacked (set `symbol->rows` to 0)
- test suite: move `test_perf` routines into single test
"test_perf";
new "test_random" (based on "test_bwipp") to test various
symbologies with random binary - discovered CODABLOCKF bug;
expand "test_bwipp"
manual: Feeback: mention AZTEC -1 meaning min & MICROPDF417:
doc new `ZINT_CAP_BINDABLE`
general: various code fiddlings and re-formattings
fields `raw_segs` and `raw_seg_count` instead of `text`, and to
do so for all symbologies, using new common funcs `rt_cpy()` etc.
MICROPDF417: return ECC percentage in top byte of `option_1`
DBAR_EXP_STK: return `option_2`/`option_3` feedback
CLI: change warning text "ignoring" -> "**IGNORED**"
GUI: show feedback for DBAR_EXP_STK, MICROPDF417, UPNQR
ctest: fix recent inability to run tests via "ctest" on Windows
(MSVC) by using cmake 3.22 feature `ENVIRONMENT_MODIFICATION`
manual: document feedback and RAW_TEXT in new "Feedback" section;
rephrase some symbology descriptions
test suite: new general-use arg "-a"; add `func_name` to context;
new "test_bwipp" test for testing BWIPP against ZXing-C++
DOTCODE/GRIDMATRIX/HANXIN/MICROPDF417/MICROQR/PDF417/QRCODE/
RMQR/ULTRA: set `option_1/2/3` to values used in encodation
("Feedback options"), and add new access methods
`encodedOption1()` etc. to Qt Backend, and use in GUI to provide
better feedback on "Automatic" selections
- AZTEC: give more precise warnings in low ECC situations, and
indicate via `option_1` by setting to -1 (min 3 words), 0
(<5% + 3 words) (`ecc_ratio`)
- set_height: fix non-compliance false positives by using epsilon
in checks (prompted by CODABLOCKF non-compliant warning for
zint-generated compliant height - floating point `rows` mult !=
`zero_count` div; one test regression for CODE93);
better warning messages on non-compliant heights (min/max)
- manual/man page: fix DATAMATRIX Sizes tables "28 12x26" ->
"27 12x26"
- GUI: AZTEC/CODEONE: add Zint versions to comboboxes
- DOTCODE: improve error messages re size too small/large
- ULTRA: better ZINT_TEST codeword dump (ZINT_DEBUG_TEST)
- general: various tabs -> spaces; prettify main .rc files;
trailing spaces; small amount of code fiddling (CODE16K)
to suppress warnings about `errtxtf` operand number "%<n>$" args;
enable some further warnings
test suite: enable -Wpedantic and fix/suppress any warnings
encodation in certain cases (and no pessimizations found so far),
props lyngklip (BWIPP);
fix extended char latching when exactly 3 extended chars at end;
count code set C (not digits) in loop deciding when to
shift/latch to extended for better estimate
AZTEC: return warning if ECC < 5% (due to bit-stuffing when version
given); return error if > 22 layers (Zint 26) for Reader
Initialisation symbol requested for better error message
AZTEC/HANXIN/QRCODE: consolidate different ECC data size tables
into one indexed by ECC
DBAR_EXP: check for reduced length <= 77 up front for better error
message
HANXIN: use `malloc()` rather than `z_alloca()` for large binary
array
QRCODE: `ecc_level` now 0-based (not 1-based)
MICROQR: consolidate different version end routines into one
`microqr_end()` and use new `microqr_data` table to simplify code
MICROPDF417: use table for max codewords per column
library: centralize all error messages using new `errtxt()`,
`errtxtf()`, `errtxt_adj()` funcs that protect `symbol->errtxt`
from overflow, & try to make error messages more consistent
thru-out, adding more feedback info to many, & use positional
args "%n$" in prep for l10n (maybe);
`is_sane/is_sane_lookup()` -> `not_sane/not_sane_lookup()`,
returning 1-based position (zero on failure) instead of bool;
`long` ints -> plain `int` (except those dealing with `ftell()`,
`fread()` etc) as depend on int being 32-bits already
GUI: in "grpDATF.ui" use "PlainText" rather than "RichText" for
tracker ratio examples as height of text messing up sometimes
manual: clarify Codablock-F length maximum & add examples
docs: README: pandoc 3.5, Ubuntu 24.04
CMake: use "-Wpedantic" for Clang only as GNU complains about
`errtxtf()` positional args "%n$"
`EANUPC_GUARD_WHITESPACE`, CLI `--guardwhitespace`) (ticket #287)
EAN-2/EAN-5: HRT now at top instead of at bottom for standalones,
following BWIPP
CLI: batch mode: don't close input if stdin
EAN/UPC: fix excess 1X to right of add-ons
Composites: fix excess whitespace; fix quiet zone calcs to allow
for linear shifting
CLI: use own (Wine) version of `CommandLineToArgvW()` to avoid
loading "shell32.dll"
Move "font.h" -> "raster_font.h"
EPS/SVG: use new `out_putsf()` func to output floats, avoiding
trailing zeroes & locale dependency
EPS: simplify "TR" formula
SVG: change font from "Helvetica, sans serif" to "OCR-B, monospace";
use single "<path>" instead of multiple "<rect>"s to draw boxes
(reduces file size)
Add `EMBED_VECTOR_FONT` to `output_options` (CLI `--embedfont`) to
enable embedding of font in vector output - currently only for
SVG output of EAN/UPC
GUI: use "OCR-B" font for EAN/UPC and "Arimo" for all others (was
"Helvetica" for both); paint background of screen preview light
grey so as contrasts with whitespace and quiet zones
EMF: prefix funcs with `emf_`; simplify string `halign` handling
large: rename `large_int` -> `large_uint`
CODE128/common: move `c128_hrt_cpy_iso8859_1()` to
`hrt_cpy_iso8859_1()` and add `ZINT_WARN_HRT_TRUNCATED` warning
(for future use)
Various symbologies: replace `printf()` with `fputs()`
(symbol->debug)
QRCODE: better assert(), removing a NOLINT (2 left)
CLI: add some more barcode synonyms for DBAR
common: various fiddlings
CMake: don't include png.c unless ZINT_USE_PNG (avoids clang
warning)
spanning Text segments to avoid affecting 1st char of 2nd segment

arg and returning error if so rather than continuing to process
- manual: MSE typo -> MSI, a few other changes; adjust SVG scaling for PDF
manual; pandoc 2.19.2
replace double-slash comments with old-skool slash asterisk ones;
define uint16_t etc for Windows ourselves and remove ms_stdint.h &
stdint_msvc.h as no longer used;
(backend (excepting test suite) now C89 compatible)
LICENSE: move from backend to root and move COPYING to frontend, with
copies in frontend_qt & backend_qt, so in where it applies;
add LICENSE section from manual to root README
- make Sequence Format textbox bigger (on own line)
- suppress question mark in Windows dialogs
AUSPOST: more standard error messages
backend: add & use z_isdigit/upper/lower() macros
docs: 20-bit Unicode -> 21-bit Unicode
GRIDMATRIX, HANXIN, MAXICODE, MICROPDF417, PDF417, QRCODE, RMQR, ULTRA

some small performance improvements through if/elses, pdf_textprocess()
& pdf_numbprocess() loop simplifications
MICROQR: fix debug access crash on printing non-NUL-terminating binary
DATAMATRIX: fix missing ++ from "[tp]" at C40/TEXT EOD processing of GS1
(though probably never reached); use "[tp++]" throughout
Add const to static tables missing it and also to some variables
Change "debug" -> "debug_print" throughout
- use fixed-length string tables (mostly) instead of (char *) pointer ones
(saves ~40K)
- re-use C128Table for CODABLOCKF and CODE16K
(required removal of Stop character and extra CODE16K-only entry)
- use pointer to destination and copy (memcpy/strcpy(), bin_append_posn())
instead of concatenating (strcat()) (mostly)
- replace last remaining bin_append()s with bin_append_posn();
bin_append() removed
- add length arg to toupper() and expand() (avoids strlen())
- change is_sane() to use table-based flags (avoids an iteration)
- rename lookup() to is_sane_lookup() and change to check and return posns
and use in pointer to destination loops (avoids strcat()s)

- make #define SILVER/CALCIUM/TECHNETIUM/KRSET etc static strings
- replace strchr() -> posn()
- CODE128: populate destination once in checksum loop; re-use and export
some more routines (c128_set_a/b/c(), c128_put_in_set()) for sharing;
prefix defines (SHIFTA -> C128_SHIFTA etc) and existing exported routines
- use factor XOR toggle trick in checksum calcs (avoids branch)
- raster.c: fill out single 1-pixel row and copy using new draw_bar_line(),
copy_bar_line() routines; similarly in buffer_plot compare previous line &
copy if same (same technique as used to improve non-half-integer scaling,
significant performance increase, (c) codemonkey82);
also done for PNG (BMP/GIF/PCX/TIFF not done)
- raster/vector/output.c: shorten "output_" prefix -> "out_";
sync vector to other raster changes to try to keep source files similar

Patch from Michael <virtual_worlds@gmx.de>
Full text: As usual I have modified only minor things to remove warnigs when compiled as C++ code, have added some const-specifiers where possible to help the compiler create more efficient code and added some static-specifiers to make functions invisible to other modules.
