#Turbopack

Next.js 16.3.0-canary brings fine-grained prefetch configuration, better deduping for the 'use cache' directive, and a redesigned blocking route dev overlay — with sccache now bootstrapped via cargo-binstall.

Oxc v0.126.0 ships support for Turbopack magic comments in the parser, a breaking rename of Box and Vec allocator methods, new NAPI transform options for enum optimization, and continued performance work on the lexer and allocator.
