"Release Notes for the WebView2 SDK", Prerelease 145

[mikehoffms]

Closed without Merging, b/c:

• Renamed underlying branch.
• Needed to remove Release section.
• PR became for Prerelease 145 only, not including Release 144.
• Underlying branch name is 144; Prerelease content is good and is for 145 instead.

Rendered article sections for review:

• Release Notes for the WebView2 SDK

  • /webview2/release-notes/index.md
  • Release SDK 1.0.####.##, for Runtime 144
    • Internal preview: https://review.learn.microsoft.com/microsoft-edge/webview2/release-notes/?branch=pr-en-us-3663&tabs=dotnetcsharp#release-sdk-10-for-runtime-144
    • External preview: https://github.com/MicrosoftDocs/edge-developer/blob/user/mikehoffms/wv2-relnotes-144/microsoft-edge/webview2/release-notes/index.md#release-sdk-10-for-runtime-144
    • Before/live: https://learn.microsoft.com/microsoft-edge/webview2/release-notes/#release-sdk-10-for-runtime-144
    • New section.
  • Prerelease SDK 1.0.3796-prerelease, for Runtime 145
    • /webview2/release-notes/index.md
    • Internal preview: https://review.learn.microsoft.com/microsoft-edge/webview2/release-notes/?branch=pr-en-us-3663#prerelease-sdk-103796-prerelease-for-runtime-145
    • External preview: https://github.com/MicrosoftDocs/edge-developer/blob/user/mikehoffms/wv2-relnotes-144/microsoft-edge/webview2/release-notes/index.md#prerelease-sdk-103796-prerelease-for-runtime-145
    • Before/live: https://learn.microsoft.com/microsoft-edge/webview2/release-notes/#prerelease-sdk-103796-prerelease-for-runtime-145
    • New section.
  • Global in file:
    • Noted the article's aka link.
    • In each Release Date line (for older entries, for which cannot alter h2 heading), added the Runtime major version, eg:
      Release Date: December 8, 2025, Runtime 143
      • To normalize and facilitate Maintenance, eg cross-linking across:
        • WebPlatform What's New
        • DevTools What's New
        • WebView2 RelNotes
      • Fixed: The important Runtime number is buried hidden mid-sentence; too hard to spot, impedes Maintenance.
  • Moved h2 sections from archive.md to index.md so that index.md covers the past year instead of only 5 or 6 months, increasing the chance of Finding the previous, phase 1 or phase 2 section in index.md.

• Archived Release Notes for the WebView2 SDK

  • /webview2/release-notes/archive.md
  • Internal preview: https://review.learn.microsoft.com/microsoft-edge/webview2/release-notes/archive?branch=pr-en-us-3663
  • External preview: https://github.com/MicrosoftDocs/edge-developer/blob/user/mikehoffms/wv2-relnotes-144/microsoft-edge/webview2/release-notes/archive.md
  • Before/live: https://learn.microsoft.com/microsoft-edge/webview2/release-notes/archive
  • Added Detailed contents at top.
  • Moved h2 sections from archive.md to index.md so that index.md covers the past year instead of only 5 or 6 months, increasing the chance of Finding the previous, phase 1 or phase 2 section in index.md.

• RelNotes templates

  • /webview2/release-notes/includes/templates.md
  • External preview: https://github.com/MicrosoftDocs/edge-developer/blob/user/mikehoffms/wv2-relnotes-144/microsoft-edge/webview2/release-notes/includes/templates.md
  • In h2 headings, added "Release" or "Prerelease" at start.
  • In h2 headings, added ", for Runtime 123" at end.
  • h2 pattern changes apply to new sections; can't change headings for past year, would break auto-scroll from links in announcement Issues.
