+====================================================
+
+**Incompatible changes**
+------------------------
+- New `memfile` & `memfile_size` fields in `symbol` for use with new output
+  option `BARCODE_MEMORY_FILE`
+- Buffer length of member `text` (HRT) in `zint_symbol` extended 200 -> 256
+  (client buffers may need checking/extending)
+- Invalid `input_mode` now returns warning
+- Aztec Code symbols that due to input length & user-requested version have less
+  than recommended 5% error correction codewords now return warning
+- New CODE128-only special extra escapes beginning `\^`
+- Add-ons for UPC-A and UPC-E now descend to be level with the main symbol guard
+  bars, and the righthand outside digit is now placed 1X less from main symbol
+  to avoid touching any add-on
+- GS1-128 symbols now warn if READER_INIT option used
+
+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
+- CODE16K (was for CODE128): improve encodation on A/B shifting, props Daniel
+  Gredler (Okapi)
+- CODE128: add new extra escape `\^1` for manual insertion of FNC1s, ticket
+  #324, props Jim Shank;
+  new  extra escapes `\^A`, `\^B`, `\^C` and `\^@` for manual switching of
+  Code Sets;
+  add minimal encodation algorithm, props Alex Geller (ZXing) and Bue Jensen
+  (BWIPP);
+- library: return warning on invalid `input_mode` reset
+- library/CLI: expanded error messages
+- GS1: new AIs 7250-7259 (GSCN 22-246);

+  OkapiBarcode, props Daniel Gredler;
+  add minimal encodation algorithm, props Bue Jensen (BWIPP)
+- GUI: use X11 (xcb) as platform instead of Wayland on Linux to avoid various
+  weird behaviours;
+  in "grpDATF.ui" use "PlainText" rather than "RichText" for tracker ratio
+  examples as height of text messing up sometimes
+- UPCA/UPCE: descend add-ons to same level as guards and adjust righthand
+  outside digit to be 4X/2X instead of 5X/3X away from main symbol so as not to
+  touch add-on TODO: revisit when standard clarified
+- manual: make explicit that AI "(00)" and "(01)" prefixes added by Zint are
+  HRT-only; clarify Codablock-F length maximum & add examples

+
+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

+===========================
+

+  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

+  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
+-------

+  Code Set switching via `input_mode` flag `EXTRA_ESCAPE_MODE` (CLI --extraesc)

+  (allows unsetting of X-dim/resolution settings without having to zap)

+- GUI: rearrange some Appearance tab inputs (Border Type <-> Width, Show Text

+  & 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)

+========================
+
+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.
+

+- Ticket 183: Databar stacked separator correction
+- Ticket 182: Output bitmap type was char, where some targets assigned 0
