## [Unreleased]

No changes yet.

## [0.2.0] — 2026-07-15

First public pre-release of the header-only C99 terminal UI library: a
single-header release artifact, POSIX terminal backend, deterministic parser and
renderer tests, release/website automation, modern terminal capability
diagnostics, image protocol support, and a pile of adversarial hardening. No
ncurses. No runtime circus.

### Added
- **Refinement release gates**: `make fuzz` now runs a deterministic
parser/image adversarial corpus, and the release runbook documents local

### Initial prototype baseline

First tagged release. A working immediate-mode C99 TUI — terminal backend,
incremental input parser, truecolour diff renderer, and a themed widget set —
hardened over seven review rounds (ASAN/UBSAN clean, 182 unit tests).
The initial internal 0.2.0 baseline already had a working immediate-mode C99 TUI
— terminal backend, incremental input parser, truecolour diff renderer, and a
themed widget set — hardened over seven review rounds (ASAN/UBSAN clean, 182

### Added
#### Added
- **In-line cursor editing** for text inputs. `timui_text_area` and the new
`timui_input_field` support Left/Right (by codepoint), Home/End (line bounds),
Backspace/Delete (before/at the cursor), and mid-string insertion.

### Changed (breaking)
#### Changed (breaking)
- **`timui_ui_resize` now returns `TimuiResult`** (was `void`) so a resize-time
out-of-memory is signalable.

list-widget scaffolding; stopped implementation-only macros/typedefs leaking
