# Changelog

All notable changes to Drafter are documented here.
Versions marked with ★ were published to Hex.pm.

## [0.1.13] - 2026-03-14 *
### Added
- Multi-series line charts: pass a list of series (list of lists) to `chart_type: :line`
- Multi-series scatter charts: pass a list of point-lists to `chart_type: :scatter`
- `:clustered_bar` chart type — grouped multi-series bars with half-block resolution
- `:stacked_bar` chart type — series stack from baseline; supports mixed positive/negative values
- `:range_bar` chart type — each bar spans a `[low, high]` range
- Negative value support documented and verified across all chart types
- `multi_series_charts.exs` example demonstrating all new chart variants

### Changed
- `Chart` moduledoc expanded with sections for negative values, multi-series API, and all bar types

## [0.1.11] - 2026-03-14 ★
### Added
- Scrollable viewport culling: off-screen children skipped during `render_component` calls,
  reducing GenServer traffic per frame for large scrollable lists

### Changed
- `count_component_slots/1` introduced to advance the ID counter for culled components,
  preserving auto-generated widget IDs for on-screen widgets

## [0.1.10] - 2026-03-14
### Fixed
- Chart axis labels: float concatenation crash in `format_axis_value/1` for values ≥ 1000

## [0.1.9] - 2026-03-14
### Fixed
- Binding resolution: `Checkbox` now reads `:checked` from opts at mount (was always `false`)
- `ComponentRenderer` checkbox update path now syncs `:checked` and `:on_change` on re-render
- `ComponentRenderer` `radio_set` update path now passes `:options` and `:selected` (was only
  `:on_change` and `:classes`, leaving options frozen after mount)
- `RadioSet.update/2` no longer resets `highlighted_index` on every timer-driven re-render

## [0.1.8] - 2026-03-14 ★
### Added
- Differential rendering in compositor: row-level dirty detection via `Strip.cache_key`
  (`:erlang.phash2` hash); unchanged rows skipped each frame, drastically reducing
  terminal output on static or partially-static screens
- Stale test cleanup: removed 10 test files referencing renamed/removed modules

### Fixed
- `TextInput`: scroll offset was double-subtracting border width, causing scroll to
  trigger 2 characters early
- `TextInput`: typed text no longer reset on re-render when widget has no `:bind` or
  `:value` prop

## [0.1.6] - 2026-03-14 ★
### Fixed
- `RadioSet`: options passed as raw tuples were not normalised at mount; now always
  stored as `%{id: _, label: _}` maps
- `RadioSet`: options not updating on re-render after first mount
- `RadioSet`: `highlighted_index` frozen after navigating before first selection

## [0.1.5] - 2026-03-14 ★
### Added
- `Collapsible` widget now supports interactive child widgets (buttons, inputs, etc.)
  inside the expanded body, not just plain text

### Fixed
- `Collapsible.update/2`: `content_height` no longer inherits stale value when content
  type changes between renders

## [0.1.4] - 2026-03-13 ★
### Fixed
- SSH: reverse entry bug introduced when SSH support was added
- Local startup issues with terminal initialisation

## [0.1.3] - 2026-03-13 ★
### Fixed
- Input handling cleanup following SSH integration

## [0.1.2] - 2026-03-13 ★
### Added
- Guide: Remote TUI over SSH/Telnet (`guides/remote_tui.md`)

## [0.1.1] - 2026-03-13 ★
### Added
- SSH and Telnet remote TUI support via `Drafter.Server`
