Changelog

The 0.10.0 section of CHANGELOG.md, restated by category, one bullet here for each entry there. The file carries the reasoning and the measurements; this page carries what changed.

0.10.0

ophtml 0.10.0, @ophtml/layout 0.10.0, tagged v0.10.0. pip install ophtml and npm install -g @ophtml/layout give you this release, and ophtml.elf is on its GitHub Release.

Added

  • The OPHTML console (console/): a PS2 program that lists the ISOs on USB, an exFAT HDD, MX4SIO or MMCE through any theme that uses its names (game-{i}, sel-title, status, ...) and starts the chosen one with Neutrino. It boots in the emulator; no console has run it yet. See console/README.md.
  • ps2ui check checks a console theme's names (gaps in the rows, rows on the wrong screen, slots the console never fills, slots too short for what it writes), and ps2ui serve --console fills a theme with mock games and walks its list the way the console does. See ps2ui-check.
  • Hard caps on what a theme may ask the compilers for: canvas dimensions, element count, nesting depth and source-image pixels. Each is derived from the shipped examples, each fails rather than warns, and each is overridable in ps2ui.json beside vramBudget.
  • ophtml.elf is attached to each tagged version's GitHub Release, with its mock build and checksums, and a new page covers running it with Neutrino and your own theme. It has not yet run on a console. See Console launcher.
  • check-versions.py fails when a released CHANGELOG section differs from the same section at its tag, so a merge can no longer add entries to a release that already shipped.
  • The .uib loader is fuzzed, for a minute on every change and half an hour nightly, and ps2ui check is fuzzed over mutated example blobs. Run it with make -C runtime fuzz.

Changed

  • registry.yml no longer runs 0.8.0's fribidi remedy steps or asserts that a plain macOS or Windows install refuses; it requires the committed tables from one instead, and fails by name when pip is served a release from before 0.9.0. See Compatibility.

Fixed

  • A .uib whose tables were not 4-byte aligned crashed the console in ps2ui_arena_size or ps2ui_load. Both refuse it now, with PS2UI_ERR_ALIGN, before reading a table. See Errors and constants.
  • ps2ui check printed a Python traceback, not a verdict, for a blob with a table past its end, an unknown texture format, or a reference past a table.

  • A raised --vram-budget bought room for a framebuffer, which no budget can. A 30000x30000 canvas baked to a blob with exit 0, past a message saying a narrower canvas was the only fix.

  • A 439 KiB image could cost 432 MB and eleven seconds of bake time, or end the bake in a Pillow traceback. The size is read from the header now, before any decode.

  • Nesting deep enough reported Maximum call stack size exceeded, which is the interpreter's stack rather than a decision: it gives out at 1842 here and at 889 or 7781 with the stack sized down or up. The refusal is the compiler's now, at 64, and names the line.

Format

.uib format version 7, unchanged since 0.9.0. python3 tools/check-versions.py --except-tag holds the packages, the format document and this section to each other:

ok - @ophtml/layout 0.10.0 and ophtml 0.10.0 are the same version in the two spellings
ok - PS2UI_VERSION and uib.VERSION are both 7
ok - docs/format-uib.md's header table says version 7
ok - docs/format-uib.md's Versioning list explains v7
ok - CHANGELOG's newest section is headed '0.10.0 — 2026-09-26', dated, and is the release the packages carry
ok - CHANGELOG's open section names format v7
ok - CHANGELOG's 0.9.0 section records the format it shipped (v7)

A v7 blob loads under every release from 0.3.0 on; see Compatibility.

Earlier releases

version date format headline
0.9.0 2026-09-23 v7 ps2ui fontgen measures kerning with HarfBuzz through uharfbuzz, so a stock macOS or Windows install no longer refuses over a missing fribidi.
0.8.0 2026-09-23 v7 The first release with Windows and Intel Mac arms in CI, three Windows fixes among what they found, and every version this site prints held to what a command prints.
0.7.0 2026-09-17 v7 ps2ui vendor-runtime --starter, a :focus rule that cannot change layout, and eight CSS keywords checked instead of accepted.
0.6.0 2026-09-12 v7 ps2ui_offset_set moves a screen at draw time, and ps2ui check is given the settings ps2ui build was.
0.5.0 2026-09-06 v7 ps2ui vendor-runtime ships the C runtime from the installed package; the console half needs no clone.
0.4.0 2026-09-06 v7 The .uib v7 stability pledge, and vendored DejaVu fonts for a checkout with no system font.
0.3.0 2026-09-04 v7 First tagged release. Breaking authoring and runtime changes; four format moves land, v4 through v7.
