release: v7.0.0

[stevenjoezhang]

Summary

• Bump the package version to 7.0.0.
• Update the database fixture metadata for the new Warehouse version.

Why

Warehouse 6.0.0 was published before several important changes currently on master. In particular, #277 changes database export to write JSON incrementally through a write stream with backpressure instead of materializing an entire model as one string and then copying it into a buffer.

That patch significantly reduces the export-time memory spike and addresses the main failure mode discussed in hexojs/hexo#4922 for large databases. Publishing a new major version makes this improvement available to downstream consumers. A single exceptionally large document may still hit the JavaScript string-size limit because each document is serialized independently.

Other changes included since v6.0.0 include:

• fix: fix ts error #281, which fixes the Buffer schema type import.
• chore: update eslint #286, which updates ESLint and migrates the project to flat config.
• All other commits currently merged into master after v6.0.0.

Downstream projects such as Hexo will need a follow-up dependency bump to warehouse@^7.0.0 because their current ^6.0.0 range will not select this major release.
