- Then share your plan for which issues to tackle and in what order.
After triaging, follow this order:

## Style Guide
- S-1e4fdef2 | src/content/docs/workers/wrangler/bundling.mdx:30 | Time-sensitive month and year in prose
Per the time-sensitive content rule, prose outside `src/content/changelog/` must not contain month names or four-digit years. `November 17, 2026` appears in plain prose here (not in a code block, backtick span, frontmatter field, URL, or example data).Style Guide

Announce that the new JavaScript module registry becomes the default for compatibility dates on or after November 17, 2026. Add compatibility-flag documentation and migration guidance, update the bundling reference, and add an October 17 advance changelog with an
import.metaexample and guidance for opting in early or retaining the legacy registry. Python Workers retain the legacy registry.Companion runtime PR: cloudflare/workerd#7799. Publish the documentation before November 17 so developers can test ahead of the default change. The changelog date is the announcement date; the compatibility boundary is November 17. Migration guidance covers import-attribute validation,
require(esm)return values, top-levelawait, and legacy-registry-only flags.Validation: Astro and Worker type checks, changelog Prettier formatting, and
git diff --checkpass. Full-site builds were not completed locally.Documentation checklist
