重要变化
架构(Stack)更新
- Chromium
80.0.3987.86
- Node.js
12.13.0
- V8
8.0
Highlight Features
- Implemented usage of Chrome's built-in spellchecker feature. See more details in #20692 and #21266.
- IPC communication now uses v8's Structured Clone Algorithm. This is faster, more featureful, and less surprising than the existing logic, and brings about a 2x performance boost for large buffers and complex objects. Latency for small messages is not significantly affected. See more details in #20214.

重大更改
- Show module name in deprecation warning for context-aware modules. #21952
- This is continued work for a future requirement that native Node modules loaded in the renderer process be either N-API or Context Aware. Full info and proposed timeline is detailed in this issue.
- Values sent over IPC are now serialized with Structured Clone Algorithm. #20214
- Offscreen Rendering is currently disabled due to lack of a maintainer to work on this feature. It broke during the Chromium upgrade and was subsequently disabled. #20772
