chore: update seroval to 1.6.2

[Sheraff]

Summary

• update seroval and seroval-plugins to 1.6.2 across the affected Router and Start packages
• update the SSR benchmark dependency and refresh the pnpm lockfile
• add patch changesets for the five affected public packages

Why

This adopts the latest Seroval serialization fixes, Temporal support, constructor serialization compatibility, restored CJS/ESM builds, and Promise-deserialization validation. The upstream changelog and published package diff did not show an API migration requirement.

Validation

• CI=1 NX_DAEMON=false pnpm nx run-many --target=test:unit --projects=@tanstack/router-core,@tanstack/start-client-core,@tanstack/start-server-core,@tanstack/start-static-server-functions,@tanstack/start-plugin-core --outputStyle=stream --skipRemoteCache
• CI=1 NX_DAEMON=false pnpm nx run-many --target=test:types --projects=@tanstack/router-core,@tanstack/start-client-core,@tanstack/start-server-core,@tanstack/start-static-server-functions,@tanstack/start-plugin-core --outputStyle=stream --skipRemoteCache
• pnpm exec changeset status
• CommonJS and ESM import smoke tests for seroval and seroval-plugins/web
• git diff --check

Summary by CodeRabbit

• Chores

  • Updated serialization dependencies to version 1.6.2 across supported packages and SSR benchmarks.

• Release

  • Prepared patch releases for six packages to incorporate the dependency updates.

_{Comparing codex/update-seroval-1-6-2 (8bdd62e) with main (704145c)¹}

Footnotes

1. No successful run was found on main (314098e) during the generation of this report, so 704145c was used instead as the comparison base. There might be some changes unrelated to this pull request in this report. ↩

[Sheraff]

Summary

• update seroval and seroval-plugins to 1.6.2 across the affected Router and Start packages
• update the SSR benchmark dependency and refresh the pnpm lockfile
• add patch changesets for the five affected public packages

Why

This adopts the latest Seroval serialization fixes, Temporal support, constructor serialization compatibility, restored CJS/ESM builds, and Promise-deserialization validation. The upstream changelog and published package diff did not show an API migration requirement.

Validation

• CI=1 NX_DAEMON=false pnpm nx run-many --target=test:unit --projects=@tanstack/router-core,@tanstack/start-client-core,@tanstack/start-server-core,@tanstack/start-static-server-functions,@tanstack/start-plugin-core --outputStyle=stream --skipRemoteCache
• CI=1 NX_DAEMON=false pnpm nx run-many --target=test:types --projects=@tanstack/router-core,@tanstack/start-client-core,@tanstack/start-server-core,@tanstack/start-static-server-functions,@tanstack/start-plugin-core --outputStyle=stream --skipRemoteCache
• pnpm exec changeset status
• CommonJS and ESM import smoke tests for seroval and seroval-plugins/web
• git diff --check

Summary by CodeRabbit

• Chores

  • Updated serialization dependencies to version 1.6.2 across supported packages and SSR benchmarks.

• Release

  • Prepared patch releases for six packages to incorporate the dependency updates.

Summary

• update seroval and seroval-plugins to 1.6.2 across the affected Router and Start packages
• update the SSR benchmark dependency and refresh the pnpm lockfile
• add patch changesets for the five affected public packages

Why

This adopts the latest Seroval serialization fixes, Temporal support, constructor serialization compatibility, restored CJS/ESM builds, and Promise-deserialization validation. The upstream changelog and published package diff did not show an API migration requirement.

Validation

• CI=1 NX_DAEMON=false pnpm nx run-many --target=test:unit --projects=@tanstack/router-core,@tanstack/start-client-core,@tanstack/start-server-core,@tanstack/start-static-server-functions,@tanstack/start-plugin-core --outputStyle=stream --skipRemoteCache

• pnpm exec changeset status
• CommonJS and ESM import smoke tests for seroval and seroval-plugins/web
• git diff --check

Summary by CodeRabbit

• Chores

  • Updated serialization dependencies to version 1.6.2 across supported packages and SSR benchmarks.

• Release

  • Prepared patch releases for six packages to incorporate the dependency updates.

Summary

• update seroval and seroval-plugins to 1.6.2 across the affected Router and Start packages
• update the SSR benchmark dependency and refresh the pnpm lockfile
• add patch changesets for the five affected public packages

Why

This adopts the latest Seroval serialization fixes, Temporal support, constructor serialization compatibility, restored CJS/ESM builds, and Promise-deserialization validation. The upstream changelog and published package diff did not show an API migration requirement.

• pnpm exec changeset status
• CommonJS and ESM import smoke tests for seroval and seroval-plugins/web
• git diff --check

Summary by CodeRabbit

• Chores

  • Updated serialization dependencies to version 1.6.2 across supported packages and SSR benchmarks.

• Release

  • Prepared patch releases for six packages to incorporate the dependency updates.

Footnotes

1. No successful run was found on main (314098e) during the generation of this report, so 704145c was used instead as the comparison base. There might be some changes unrelated to this pull request in this report. ↩

[Sheraff]

Summary

• update seroval and seroval-plugins to 1.6.2 across the affected Router and Start packages
• update the SSR benchmark dependency and refresh the pnpm lockfile
• add patch changesets for the five affected public packages

Why

This adopts the latest Seroval serialization fixes, Temporal support, constructor serialization compatibility, restored CJS/ESM builds, and Promise-deserialization validation. The upstream changelog and published package diff did not show an API migration requirement.

• pnpm exec changeset status
• CommonJS and ESM import smoke tests for seroval and seroval-plugins/web
• git diff --check

Summary by CodeRabbit

• Chores

  • Updated serialization dependencies to version 1.6.2 across supported packages and SSR benchmarks.

• Release

  • Prepared patch releases for six packages to incorporate the dependency updates.

Summary

• update seroval and seroval-plugins to 1.6.2 across the affected Router and Start packages
• update the SSR benchmark dependency and refresh the pnpm lockfile
• add patch changesets for the five affected public packages

Why

This adopts the latest Seroval serialization fixes, Temporal support, constructor serialization compatibility, restored CJS/ESM builds, and Promise-deserialization validation. The upstream changelog and published package diff did not show an API migration requirement.

Validation

• CI=1 NX_DAEMON=false pnpm nx run-many --target=test:unit --projects=@tanstack/router-core,@tanstack/start-client-core,@tanstack/start-server-core,@tanstack/start-static-server-functions,@tanstack/start-plugin-core --outputStyle=stream --skipRemoteCache

• pnpm exec changeset status
• CommonJS and ESM import smoke tests for seroval and seroval-plugins/web
• git diff --check

Summary by CodeRabbit

• Chores

  • Updated serialization dependencies to version 1.6.2 across supported packages and SSR benchmarks.

• Release

  • Prepared patch releases for six packages to incorporate the dependency updates.

Summary

• update seroval and seroval-plugins to 1.6.2 across the affected Router and Start packages
• update the SSR benchmark dependency and refresh the pnpm lockfile
• add patch changesets for the five affected public packages

Why

This adopts the latest Seroval serialization fixes, Temporal support, constructor serialization compatibility, restored CJS/ESM builds, and Promise-deserialization validation. The upstream changelog and published package diff did not show an API migration requirement.

Validation

• CI=1 NX_DAEMON=false pnpm nx run-many --target=test:unit --projects=@tanstack/router-core,@tanstack/start-client-core,@tanstack/start-server-core,@tanstack/start-static-server-functions,@tanstack/start-plugin-core --outputStyle=stream --skipRemoteCache

• pnpm exec changeset status
• CommonJS and ESM import smoke tests for seroval and seroval-plugins/web
• git diff --check

Summary by CodeRabbit

• Chores

  • Updated serialization dependencies to version 1.6.2 across supported packages and SSR benchmarks.

• Release

  • Prepared patch releases for six packages to incorporate the dependency updates.
