[tylerbutler]

This issue is automatically updated with a preview of the release notes for the upcoming Fluid Framework release.

To generate release notes locally to commit to the RELEASE_NOTES folder in the repo, run the following command:

pnpm flub generate releaseNotes -g client -t minor --outFile RELEASE_NOTES/2.42.0.md

To generate the release notes to paste into the GitHub Release, run the following command:

pnpm flub generate releaseNotes -g client -t minor --headingLinks --excludeH1 --outFile temporary-file.md

This should happen automatically as part of the release process, but if you need to generate the release notes manually, you can use the above command.

Name collisions from structurally named schema now error (#24707)

It is legal to have multiple TreeNodeSchema with the same name so long as they are not used together in the same tree. Using different schema with the same name when building otherwise identical structurally named in the same SchemaFactory is not valid, however. Previously doing this would not error, and instead return the first structurally named schema with that name. Now this case throws an informative error:

const factory = new SchemaFactory(undefined);
class Child1 extends factory.object("Child", {}) {}
class Child2 extends factory.object("Child", {}) {}

const a = factory.map(Child1);

// Throws a UsageError with the message:
// "Structurally named schema collision: two schema named "Array<["Child"]>" were defined with different input schema."
const b = factory.array(Child2);
