The install task for jsbundling-rails was hardcoded to Yarn even when you chose Bun, esbuild, or Webpack - that's fixed now.

Rails jsbundling-rails has merged a critical fix that finally makes the install tasks respect your package manager choice [1]. Until now, running ./bin/rails javascript:install:bun would configure everything for Bun, then the install task would force Yarn anyway. The build tasks already detected the package manager correctly, so this fix closes the gap between setup and reality. In parallel, the library now runs against Rails 8.1 in CI [2], catching integration issues earlier. On the Rails core side, PostgreSQL schema dumping for IPv6 CIDR and INET columns is getting fixed to preserve prefix notation [3]. This matters because omitting /32 prefixes on IPv6 addresses creates schema drift when you re-import. Both fixes are straightforward but solve real pain points for production systems.
