📝 WalkthroughSummary by CodeRabbit
WalkthroughThe timeline API now supports version-anchored pagination. The package timeline loads newer and older pages independently, preserves scroll position when loading newer entries, and discards stale requests after context changes. ChangesTimeline pagination

Suggested reviewers: Merge Risk: 🟡 Moderate · up to The timeline can show entries from the wrong version range if pagination is triggered while the selected-version window is loading, and a previous loading error may remain visible after valid data loads. Merge should wait for these bounded correctness and UI-state issues to be addressed. 🚥 Pre-merge checks | ✅ 4✅ Passed checks (4 passed)

Block pagination while re-anchoring.
listEpoch++ invalidates requests that started before this line. It does not block a new loadMore call while fetchTimeline({ around: ver }) is pending. The existing entries and both pagination buttons remain active. A new request can capture the new epoch. If the re-anchor completes first, that response passes the check at Line 152 and merges an old-window page into the new window.
Add a re-anchor state. Reject and disable both loadMore directions until the anchor request settles. Alternatively, increment the epoch again immediately before committing the re-anchored data.

Right now, the timeline feature ignores the currently selected version. for example, for Nuxt v3.0.0 (https://npmx.dev/package-timeline/nuxt/v/3.0.0), we have:

v3.0.0. "Load more" is also not feasible asv3.0.0is too long ago to navigate.This PR implemented a two-way "load more" feature, by default to navigate the range that contains the selected version:
