v1.0.0

Combined release archives

Each archive bundles the backend binary AND the pre-built web
frontend — unpack and run, no build step required.

Quick start

Unix (Linux / macOS):

tar -xzf sumzle-solver-<platform>.tar.gz
cd sumzle-solver-<platform>
./run.sh

Windows:

Expand-Archive sumzle-solver-windows-x86_64.zip
cd sumzle-solver-windows-x86_64
run.bat

Then open http://localhost:3000 in your browser. The backend
automatically serves the bundled frontend from frontend/dist.

See the in-archive README.md for CLI usage and advanced options.

Note: Cross-compiled binaries (ARM Linux, Windows, macOS) are not included in this manual release due to build environment limitations. Use the CI workflow with tag triggers for full multi-platform builds.

v0.1.0

sumzle-hpc-solver v0.1.0

Initial release with web frontend support.

Features

• Rust solver backend with Axum web server
• React + TypeScript + Vite frontend
• REST API endpoints: /api/solve, /api/validate, /api/eval
• Static file serving for frontend assets
• Configurable thread count for parallel solving

Bug Fixes

• Fixed JSON deserialization mismatch between frontend and backend (#3)
• Fixed empty string handling for tile characters (#3)

v0.1.0-alpha

fix: handle empty string char from frontend blank tiles

Frontend sends char: "" for blank/empty tiles, but the Rust char type
requires exactly one character. Changed SolveTile.char from char to String,
and handle conversion in to_guess_row() by mapping empty strings to null
character with Empty state.

Fixes: rows[0].tiles[0].char: invalid value: string "", expected a character

Added tests:
- test_solve_with_blank_tiles: exact scenario from bug report
- test_solve_with_partial_blank_tiles: mixed filled/blank tiles
- test_solve_tile_empty_char: unit test for empty char deserialization
- test_solve_row_with_blank_tiles_to_guess_row: conversion logic
