+It is important to call out that since June 2023, Microsoft requires software to
+be signed with an "extended validation" certificate, also called an "EV code signing
+certificate". In the past, developers could sign software with a simpler and cheaper
+certificate called "authenticode code signing certificate" or "software-based OV certificate".
+These simpler certificates no longer provide benefits: Windows will treat your app as

-- [Sectigo](https://sectigo.com/ssl-certificates-tls/code-signing)
-- Amongst others, please shop around to find one that suits your needs! 😄
+The new EV certificates are required to be stored on a hardware storage module
+compliant with FIPS 140 Level 2, Common Criteria EAL 4+ or equivalent. In other words,
+the certificate cannot be simply downloaded onto a CI infrastructure. In practice,
+those storage modules look like fancy USB thumb drives.
 
-:::caution Keep your certificate password private
-Your certificate password should be a **secret**. Do not share it publicly or
-commit it to your source code.
-:::
+Many certificate providers now offer "cloud-based signing" - the entire signing hardware
+is in their data center and you can use it to remotely sign code. This approach is
+popular with Electron maintainers since it makes signing your applications in CI (like
+GitHub Actions, CircleCI, etc) relatively easy.
+
+At the time of writing, Electron's own apps use [DigiCert KeyLocker](https://docs.digicert.com/en/digicert-keylocker.html), but any provider that provides a command line tool for
+signing files will be compatible with Electron's tooling.
+
+All tools in the Electron ecosystem use [`@electron/windows-sign`][] and typically
+expose configuration options through a `windowsSign` property. You can either use it
+to sign files directly - or use the same `windowsSign` configuration across Electron
+Forge, [`@electron/packager`][], [`electron-winstaller`][], and [`electron-wix-msi`][].

+Subject: Fix primary display race condition crash on Windows
+
+In rare cases, it's possible for the OS to provide us a list of displays
+that doesn't contain the primary display. This situation causes
+undefined behavior (dereference past vector end) and a crash to occur in
+|display::win::(anon)::DisplayInfosToScreenWinDisplays| on builds
+without DCHECK enabled.

+Subject: fix: revert "src,lb: reducing C++ calls of esm legacy main resolve"
+
+This switch to native legacyMainResolve doesn't take asar into account, and can
+cause errors when a project using ESM and asar tries to load a dependency which
+uses commonJS. This will need to be fixed forward, but revert for Electron 29's
+stable release to avoid potentially breaking apps with a riskier fix.
+
+This patch can be removed when node's
+native implementation has been patched
+to recognize asar files.
+
+This reverts commit 9cf2e1f55b8446a7cde23699d00a3be73aa0c8f1.

 Subject: src: preload function for Environment
 
-https://github.com/nodejs/node/pull/51539
-
-This PR adds a |preload| arg to the node::CreateEnvironment to allow
-embedders to set a preload function for the environment, which will run
-after the environment is loaded and before the main script runs.
-
-This is similiar to the --require CLI option, but runs a C++ function,
-and can only be set by embedders.
-
-The preload function can be used by embedders to inject scripts before
-running the main script, for example:
-1. In Electron it is used to initialize the ASAR virtual filesystem,
-   inject custom process properties, etc.
-2. In VS Code it can be used to reset the module search paths for
-   extensions.
