PouchDB Updates

Latest: 9.0.0 · 21 Jun 2024 - The PouchDB developers are delighted to announce the immediate availability of PouchDB 9.0.0. This is a major release with 202 PRs merged since the last version. For a full changelog from 8.0.1 to 9.0.0, please see the releases page or view the latest commits . The PouchDB developers would like to thank all contributors for their hard and diligent work. Highlights Massively improved the stability and performance of the indexeddb adapter. Special thanks to @alxndrsn , Medic , and the Google Advanced Web Apps Fund . Introduce a default limit (of 25 ) to the .find() method. This constitutes a backwards incompatible change and is the reason for the major version bump. Streamline the automated test suites and move in-browser testing to Playwright resulting in much more reliable test runs. Continue to update the codebase to ES6.
