# Version 5.0.8-beta
- Changed bundler to Rollup.
- Added ES6 modules for bundlers and browsers (`fuse.esm.js`) (fixed #262)
- Added CommonJS builds (`fuse.common.js`)
## Breaking Changes
- The minimified version is finally actually called `fuse.min.js`
# Version 5.0.7-beta

@@ -19,7 +29,9 @@

- Added `Fuse.createIndex`, which created and returns an index. This function can be used to pre-generate the index, which you can then save, and ultimately pass to the `Fuse` instance.
- **Breaking changes:**
- Removed `id` option
- Changed format of the search results
- Updated TypeScript definitions
