Migrating SolidJS 1.x APIs to 2.0 beta requires mapping deprecated constructs to their new equivalents and updating import paths. This patch provides specific API rename mappings and migration guidance for upgrading projects to the new reactivity model.

SolidJS 2.0 beta reactivity introduces microtask batching, split effects, and async-first computations. These updates change how batched updates and asynchronous computations are handled, requiring adjustments to existing effect logic during migration.

SolidStart 1.1 changes loading and error boundary semantics, requiring migration scenarios for existing boundaries. The patch covers how to handle these boundary updates along with draft-first stores and optimistic updates in real projects.

Handling deprecated SolidJS constructs when upgrading to 2.0 involves enforcing specific API renames and removing outdated patterns. The patch maps old constructs to new import paths and highlights removals to ensure codebase readiness.

Adopting async-first computations in SolidJS involves understanding microtask batching and split effects introduced in 2.0 beta. The patch explains these mechanisms and provides migration scenarios for updating existing reactive dependencies.

Yes, SolidJS 2.0 migration includes DOM cleanup notes alongside boundary migrations and draft-first stores. The patch details how to handle these cleanup operations correctly when upgrading from 1.x to the new reactivity model.
