v0.17.2

v0.17.2 — SSR Filtering + dsd-report Manifest Decisions

Release date: 2026-05-16

Summary

Implements the two deferred v0.17.0 SOP items: SSR-aware island filtering
(less.ssr: false) and manifest-driven render decisions in dsd-report.json.

Changes

• SSR Filtering: Islands with less.ssr: false are excluded from SSR
  customElements.define() registration. They render as empty custom element
  tags in SSR HTML and get upgraded client-side via the client entry.
• ManifestDecision type: New ManifestDecision interface in @lessjs/core
  records per-island render path (ssr+client | client-only) derived from
  manifest flags (ssr, dsd, hydrate).
• dsd-report.json: New manifestDecisions field populated from
  ctx.phase1.packageIslandDecls + ctx.phase1.packageManifests.
  Empty array when no package manifests are configured.
• Tests: 6 new tests (4 in entry-renderer, 2 in ssg-report).
  Total: 528 unit + 92 e2e passing.

Breaking Changes

None. This is a patch release — feature completion, no API change.
manifestDecisions is an optional field in DsdBuildReport.

Known Issues

• 3 JSR unanalyzable-dynamic-import warnings in adapter-vite (expected,
  runtime-only deps, not blocking publish)
