Electron 37 Breaking Changes vs Staying on Supported 38+ — when and how should I migrate?

Decide whether to absorb Electron 37-era breaking changes now or jump directly to a newer supported Electron line given the short support window and fast EOL cadence.

Jump to Electron 40 or 41 and absorb 37/38 once, unless Node 24 blocks you right now; use Electron 39 only when you can commit to another upgrade within weeks.

Blockers

Who this is for

Candidates

Use Electron 39 only as a short bridge release

As of 2026-03-20, Electron 37 reached end of life on 2026-01-13 and Electron 38 reached end of life on 2026-03-10, so neither is a supported destination. Electron 39 is still supported as of 2026-03-20, with stable release on 2025-10-28 and end of life on 2026-05-05. It stays on Node 22.20.0, which reduces runtime churn compared with Electron 40 and 41. You still inherit the Electron 37 and 38 blockers, including utility-process behavior changes, removal of `ProtocolResponse.session = null`, the macOS 12 floor, and Wayland-default behavior on Linux.

When to choose

Use this only when Node 24 migration work is the real blocker and you need a currently supported landing zone immediately. The decisive factor is whether you can commit to a second Electron upgrade within weeks, because Electron 39 support ends on 2026-05-05.

Tradeoffs

Lower immediate runtime churn and smaller hop from old Node 22-based Electron lines, but it creates a deliberate two-step migration and a very short remaining support runway.

Cautions

As of 2026-03-20, this is a bridge, not a destination. Upgrading to Electron 39 does not avoid Electron 37 or 38 breakage; it only postpones the Node 24 jump.

Jump directly to Electron 40 or 41 and absorb 37 plus 38 breaks once

As of 2026-03-20, Electron supports only the latest three stable majors, and those are 39, 40, and 41. Electron 40 was released on 2026-01-13 and is scheduled for end of life on 2026-06-30; Electron 41 was released on 2026-03-10 and is scheduled for end of life on 2026-08-25. Electron 40 also moves from Node 22.20.0 to Node 24.11.1, and Electron 41 uses Node 24.14.0. This path folds the unavoidable Electron 37 and 38 migration work into one supported upgrade instead of spending effort on already-expired lines.

When to choose

Use this as the default choice for small-team or low-ops maintenance, especially if you want one migration cycle with a longer support runway. The decisive factor is whether you can test the Node 24 jump now; if yes, skipping 37 and 38 is the cleaner move.

Tradeoffs

Best support runway and avoids paying for a bridge release, but the runtime jump is larger and you need to validate both the 37 and 38 blockers plus newer 40-era deprecations.

Cautions

Electron 38 and higher require macOS 12 or later, and Electron 38 removed `ELECTRON_OZONE_PLATFORM_HINT`, making Wayland the default on Wayland sessions unless you force `--ozone-platform=x11`. Electron 40 deprecates direct renderer access to the `clipboard` API and changes macOS debug symbol archives from `dsym.zip` to `dsym.tar.xz`.
