+### v3.10.1 2022-08-02
+
+- Add sponsorship files.
+    + If you appreciate the time spent maintaining JSZip then I would really appreciate [your sponsorship](https://github.com/sponsors/Stuk).
+- Consolidate metadata types and expose OnUpdateCallback [#851](https://github.com/Stuk/jszip/pull/851) and [#852](https://github.com/Stuk/jszip/pull/852)
+- use `const` instead `var` in example from README.markdown [#828](https://github.com/Stuk/jszip/pull/828)
+- Switch manual download link to HTTPS [#839](https://github.com/Stuk/jszip/pull/839)
+
+Internals:
+
+- Replace jshint with eslint [#842](https://github.com/Stuk/jszip/pull/842)
+- Add performance tests [#834](https://github.com/Stuk/jszip/pull/834)
+
 ### v3.10.0 2022-05-20
 
-- Change setimmediate dependency to more efficient one. Fixes https://github.com/Stuk/jszip/issues/617 (see [#829](https://github.com/Stuk/jszip/pull/829)
-- Update types of `currentFile` metadata to include `null` (see [#826](https://github.com/Stuk/jszip/pull/826)
