Issue Triage Summary — Preparing for Stable 0.30 Release

[lnagel]

I reviewed all 20 open GitHub issues against the current 0.30.0-beta.9 codebase to assess which are still relevant as we prepare for a stable release. Each issue has been commented on individually with detailed findings.

Still Relevant — Bugs to Fix Before Stable

#	Issue	Severity
#983	visibleTimeEnd wrong on first render (hardcoded width=1000)	Medium
#975	Mouse wheel zoom jumps to max (unnormalized deltaY)	High
#970	onItemSelect not firing with custom handlers (onClick not composed)	Medium
#956	Fractional timeSteps causes infinite loop	Medium
#955	Safari scroll unusable (no throttling/rAF)	High
#907	Dragging item scrolls timeline 1-2px (race condition)	Low
#900	getSumScroll crashes on detached nodes (missing null check)	Low

Still Relevant — Feature Requests

#	Issue	Priority
#943	No way to set timezone (headers always use browser TZ)	Medium
#916	Stacking: no option to force each item on its own row	Low
#959	Container resize detection could use native ResizeObserver	Low

Resolved / Can Be Closed

#	Issue	Reason
#974	Webpack build fail	Fixed — exports field updated
#971	CSS import path changed	Expected migration change
#947	Missing CSS specifier	Duplicate of #971
#939	Externalize stylesheet	Done — libInjectCss removed
#901	groupRenderer not working	User error, self-resolved

Needs More Info / Low Relevance

#	Issue	Reason
#949	Items offset by 1 month	Likely user passing wrong types
#935	Timeline not showing items	Usage issue on v0.28
#929	Touchpad scrolling too fast	Duplicate of #975/#955
#918	Scroll bug with empty groups	Edge case, needs validation
#969	Resize precision	Preact-specific, out of scope

Key Themes for Stable Release

1. Scroll event handling needs an overhaul — delta normalization, requestAnimationFrame batching, throttling (Mouse Wheel Zoom Jumps to Maximum Instead of Step-by-Step Zoom #975, Scroll is not smooth in Safari with controlled state, almost unusable #955, Touchpad scrolling is very fast and broke timeline #929)
2. Initial render width should not be hardcoded to 1000px (Issue with visibleTimeEnd on first render #983)
3. Item event composition needs onClick support in getItemProps (onItemSelect not firing when itemRenderer uses custom event handlers #970)
4. Migration guide needed for CSS imports, timestamps, dayjs (Css import and type issues in 0.30 beta #971, Missing "./lib/Timeline.css" specifier in "react-calendar-timeline" package #947, Webpack build fail after updating to the latest version 0.30.0-beta.3 #974)
