@pichlermarc I put this in the ESM related thread, but it might be worth considering not including NodeJS 18, it is out of support on 2025-04-30 (only about 6 weeks away). Then you can drop CommonJS entirely in the release (see https://antfu.me/posts/move-on-to-esm-only). Being able to |

@JakeGinnivan, thanks for reaching out. We're releasing on Monday and the release candidate is already published. That means that we'll not make any major changes to the 2.0 release anymore.

typefield to enforce naming conventions #5291 @chancancode_totalsuffix.typeto OpenTelemetry metrics #5291 @chancancodeapplyCustomAttributeshook #5281 @chancancodefetch()response in order to preserve the ability for theapplyCustomAttributeshook to consume the response body. This is fundamentally unsound, as it forces the browser to buffer and retain the response body until it is fully received and read, which crates unnecessary memory pressure on large or long-running response streams. In extreme cases, this is effectively a memory leak and can cause the browser tab to crash. If your use case forapplyCustomAttributesrequires access to the response body, please chime in on #5293.^18.19.0 || >=20.6.0. Support for Node.js 14, 16, and early minor versions of 18 and 20 have been dropped.
