Version 2.13.0.9 (dev) not released yet
=======================================
**Incompatible changes**
------------------------
- New `memfile` & `memfile_size` fields in `symbol` for use with new output
option `BARCODE_MEMORY_FILE`
- Invalid `input_mode` now returns warning
Changes
-------
- BMP: lessen heap memory usage by only `malloc()`ing a row
- GIF: lessen heap memory usage by paging; use standard colour char map
- Add `BARCODE_MEMORY_FILE` to `symbol->output_options` to allow outputting to
in-memory buffer `symbol->memfile` instead of to file `symbol->outfile`,
ticket #301
- CODE128: improve encodation on A/B shifting, props Daniel Gredler (Okapi)
- library: return warning on invalid `input_mode` reset
- GS1: new AIs 7250-7259 (GSCN 22-246), new linters `yyyymmdd()`, `iso5218()`,
`posinseqslash()`; remove old linter `iso3166list`;
iso4217: new ISO 4217 currency code 924
- AZTEC: workaround MSVC 2022 optimizer bug in `az_populate_map()` loops,
ticket #317, props Andre Maute
Bugs
----
- raster/BMP/GIF/PCX/TIF: fix dealing with very large data (use `size_t`)
- raster: add `raster_malloc()` to fail > 1GB (avoids very large output files;
also lessens to some degree chances of being victim of OOM killer on Linux)
- GUI: printing scale dialog: set maxima on X-dim and resolution to keep scale
<= 200
- BMP/EMF/PCX/TIF: fix endianness on big-endian machines (note TIF now always
written as little-endian - simplifies testing)
- ITF14/DPLEIT/DPIDENT: ignore `option_2` (check digit options)
- GUI: scalewindow: fix cropping of initial resolution and bound X-dim <= 10
- GUI: factory reset: reset preview background colour also
- QZint: fix legacy width and security level getters/setters, MR #158, props
Philip Ye
Version 2.13.0 (2023-12-18)
===========================
**Incompatible changes**
------------------------
- Buffer lengths of members `fgcolour` and `bgcolour` in `zint_symbol` extended
10 -> 16 to allow for "C,M,Y,K" comma-separated decimal percentage strings
- CMYK values for EPS (slightly) and TIF (significantly) have changed - now use
the same RGB -> CMYK formula
- Text (HRT) placement for vector (EMF/EPS/SVG) output changed - for EAN/UPC
slightly further away from barcode, for all others slightly nearer. Some
horizontal alignments of EAN/UPC vector text also tweaked
- Text (HRT) for standalone EAN-2 and EAN-5 now at top of symbol
(was at bottom)
- Text height (font size) for SMALL_TEXT vector output reduced
- For Windows, filenames are now assumed to be UTF-8 encoded. Affects `outfile`
in `zint_symbol` and all API filename arguments
- Never-used `fontsize` member removed from `zint_symbol`
- Buffer length of member `text` (HRT) in `zint_symbol` extended 128 -> 200
(client buffers may need checking/extending)
- Font of text of SVG vector output now "OCRB, monospace" (EAN/UPC) or
"Arimo, Arial, sans-serif" (all others)
(was "Helvetica, sans-serif" for both)
- Unintended excess horizontal whitespace of Composite symbols removed, and
quiet zone settings respected exactly, and centring of HRT (if any) now
relative to linear part of symbol only rather than whole symbol
- Unlikely-to-be-used `bitmap_byte_length` member removed from `zint_symbol`
(was only set on BMP output to length of BMP pixel array)
- EXCODE39 now defaults to displaying check digit in Human Readable Text (HRT)
- GS1_128 now warns if data > 48 (GS1 General Specifications max)
Changes
-------
- BMP/EMF/EPS/GIF/PCX/PNG/SVG/TIF/TXT: check for errors on writing to output
file (ticket #275)
- manual/man page: document octal escape; Code 128 subset/mode -> Code Set
- Add special symbology-specific escape sequences (Code 128 only) for manual
Code Set switching via `input_mode` flag `EXTRA_ESCAPE_MODE` (CLI --extraesc)
(ticket #204)
- GUI: disable "Reset" colour if default; add "Unset" to Printing Scale dialog
(allows unsetting of X-dim/resolution settings without having to zap)
- API/CLI/GUI: allow foreground/background colours to be specified as
comma-separated decimal percentage strings "C,M,Y,K" where "C", "M" etc. are
0-100 (ticket #281, 3rd point)
- PCX: add alpha support
- GUI: rearrange some Appearance tab inputs (Border Type <-> Width, Show Text
<-> Font, Text/Font <-> Printing Scale/Size) to flow more naturally;
save button "Save As..." -> "Save..." and add icon
- Add `text_gap` option to allow adjustment of vertical gap between barcode and
text (HRT)
- DAFT: up max to 250 chars
- CLI: use own (Wine) version of `CommandLineToArgvW()` to avoid loading
"shell32.dll"
- EAN/UPC: add quiet zone indicators option (API `output_options`
`EANUPC_GUARD_WHITESPACE`, CLI `--guardwhitespace`) (ticket #287)
- EAN-2/EAN-5: HRT now at top instead of at bottom for standalones, following
BWIPP
- 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 "OCRB, monospace" for EAN/UPC
and "Arimo, Arial, sans-serif" for all others;
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
- GUI: use "OCRB" font for EAN/UPC and "Arimo" for all others (was "Helvetica"
for both); add preview background colour option (default light grey) so as
whitespace will show up in contrast (access via preview context menu)
- CODE128/common: add `ZINT_WARN_HRT_TRUNCATED` warning
- QRCODE: better assert(), removing a NOLINT (2 left)
- CLI: add some more barcode synonyms for DBAR
- CMake: don't include png.c unless ZINT_USE_PNG (avoids clang warning)
- vector: reduce SMALL_TEXT font height 6 -> 5 to be more like raster;
reduce antialiasing allowance for `textoffset`;
adjust text to baseline using values for Arimo rather than percentage
- manual: expand size/alpha details in Section "5.4 Buffering Symbols in Memory
(raster)" (cf ticket #291); add BSD info
- EXCODE39: change to display check digit in HRT by default
- CODE39/EXCODE39/LOGMARS: new hidden check digit option
- GUI: move some symbology-specific options into Data Tab so separate tab
unnecessary
- DATAMATRIX: add `DM_ISO_144` (--dmiso144) option for ISO placement of ECC
codewords instead of default "de facto"
- manual: add annexes on Qt and Tcl backends
- CODE128: increase no. symbol chars max 60 -> 99
- frontend: truncate overlong `--primary` instead of ignoring
- man page: list size detail for matrix symbols (`--vers`)
- CODE11/C25XXX/CODE39/EXCODE39/HIBC_39/CODE93/CODABAR/PLESSEY/MSI_PLESSEY/FLAT/
DAFT/TELEPEN/TELEPEN_NUM: increase allowed lengths
- API: add `ZBarcode_Reset()` to fully restore `zint_symbol` to default state
Bugs
----
- CEPNET: fix no HRT (library: `has_hrt()`)
- man page: fix Code 11 check digit info
- CMake: allow ctest to be run without having to install zint or manually set
LD_LIBRARY_PATH and PATH (ticket #279, props Alexey Dokuchaev)
- GUI: fg/bgcolor text edit: fix right-click context menu not working properly

Version 2.8.0 2020-04-10
========================
Changes
-------
(New) Tests for auspost, codablock, composite, dotcode, general, telepen,
upcean, all output formats
- QR, Han Xin, Grid Matrix: the multi byte compaction schemes (ex: Kanji)
are used by some decoders as codepage information (Ex: GB2312) and output
may be translated to UTF-8. This may destroy the data in a not controlable
manner.
In consequence, multibyte compaction schemes are disabled by default.
The new option --fullmultibyte (option_3 = ZINT_FULL_MULTIBYTE) enables this
optimisation.
- Add new symbology "Ultra Code" with the ability to output colour codes.
Bugs
----
- Ticket 181 penetration test found many bugs:
- Auspost: null bytes in content caused segfault
- Codablock: data 0x1a..0x1f caused segfault
- Dotcode: overrun in binary mode, overrun in codeword_array buffer
Correct encoding of HT/FS/GS/RS when shifting to code set B
- empty or unreadable input file
- telepen: buffer overflow
- EANUCC: buffer overflow on multiple + (multiple extension bars)
- Maxicode: index overrun on numeric compaction
- CodeOne: Simple i indexing not sp + i in C1_ASCII numeric latch loop.
- Aztec: free memory
- Ticket 183: Databar stacked separator correction
- Ticket 182: Output bitmap type was char, where some targets assigned 0
if pixel colour >127 (e.g. negative). API change to use unsigned char.
- HanXin: wrong codepage, gb2312 instead gb18030.
- PDF417: corrected alloced sizes to max characters
- Ticket 189: FNC1 encodation fixed (FLG(0) missing after FLG(n))
- PCX format: added missing bytes_per_line if bitmap width is odd.
