Highlights 💡

Drop support for Node 16

Node.js 16 reached its end-of-life on September 11, 2023. Many other npm packages in the ecosystem have also dropped support for Node 16, including webpack-dev-server, css-loader, sass-loader, and so on, which makes maintaining compatibility increasingly challenging. Therefore, we have decided to drop Node 16 support starting from Rslib v0.12 to ensure better compatibility with the modern ecosystem.

Package	v0.11	v0.12
@rslib/core	>=16.7.0	>=18.12.0

Rslib v0.11 based on Rsbuild/Rspack v1.4 and Rslib v0.12 based on Rsbuild/Rspack v1.5:

Package	v1.4	v1.5
@rspack/core	>=16.0.0	>=18.12.0
@rsbuild/core	>=16.10.0	>=18.12.0

⚠️ This is a breaking change for users still running Node.js 16. Users will need to upgrade to Node.js 18.12.0 or later to use Rslib v0.12.

For users currently using Node.js 16:

1. Upgrade to Node.js 18.12.0 or later (Node.js 22 LTS is recommended)
2. Update your CI/CD pipelines to use the new Node.js version
