my-cards v2.2.0-beta.2

Beta release — all changes below are opt-in or behavior-preserving. Existing configs work unchanged.

New features

Show value while dragging (#23) new showValue: true option for my-slider-v2.
A floating bubble appears above the thumb and follows it while you drag, showing the value. Hidden when not interacting. Fully
styleable via styles: value:. Note: don't put overflow: hidden on styles: card: or the bubble gets clipped, the container is the right place for it. See the docs for examples.

type: custom:my-slider-v2
entity: light.livingroom
showValue: true

Attribute sliders (#48) new attribute: option to read/write an entity attribute instead of its state. The classic use case: humidifier target humidity. The range defaults from the entity's own min_<attribute>/max_<attribute> attributes when present (override with min:/max:), and writes go through the domain's set_<attribute> service. Entities outside the normally supported domains are allowed
when attribute: is set.

type: custom:my-slider-v2
entity: humidifier.laundry_room
attribute: humidity

Fixes

styles: thumb: right: was silently ignored on vertical sliders.
Dragging a slider in the instant before its first render threw an uncaught TypeError and could leave the slider unresponsive.
Performance/memory: every entity state change permanently added document-level event listeners that all ran on every mouse move and kept removed cards alive. Listeners are now registered once per card and cleaned up on removal.

Documentation

New "Attribute sliders" section with examples.
Previously undocumented options documented: sliderId (including the default id format and the data-value/data-progress-percent attributes), showValue.
Corrected supported-domains list (number, input_boolean were missing) and the disableScroll default description; the styles: components are now listed.

Internal (no user-facing changes intended)

Build toolchain modernized: rollup 1 → 4, TypeScript 3.9 → 6, official @rollup plugins, babel removed. Dependencies pruned and updated.
Slider internals cleaned up: duplicated per-entity math extracted into tested pure functions, single deflate implementation, fewer redundant computations per render.
Test suite grown to 155 tests, including a smoke test of the actual built bundle.

For beta testers

Everything above is covered by automated tests, but real-dashboard feedback is welcome. Let me know if anything changes regarding drag/tap feel on every slider type you use (the input path was reworked), the showValue bubble in tight layouts (stacks, grids, card_mod), and attribute: with a humidifier or similar devices. Please report anything odd in the relevant issues or feel free to create new ones.
