+Version 6 changes are documented in [this issue](https://github.com/naptha/tesseract.js/issues/993).  Highlights are below.
+ - Fixed memory leak in previous versions
+ - Overall reductions in runtime and memory usage
+ - Breaking changes:
+    - All outputs formats other than `text` are disabled by default.
+      - To re-enable the `hocr` output (for example), set the following: `worker.recognize(image, {}, { hocr: true })`
+    - Minor changes to the structure of the JavaScript object (`blocks`) output

 ## Major changes in v5
 Version 5 changes are documented in [this issue](https://github.com/naptha/tesseract.js/issues/820).  Highlights are below.
 
  - Significantly smaller files by default (54% smaller for English, 73% smaller for Chinese)
     - This results in a ~50% reduction in runtime for first-time users (who do not have the files cached yet)
  - Significantly lower memory usage
- - Compatible with iOS 17 (using default settings)
  - Breaking changes:
     - `createWorker` arguments changed
        - Setting non-default language and OEM now happens in `createWorker`
           - E.g. `createWorker("chi_sim", 1)`
-    - `worker.initialize` and `worker.loadLanguage` functions now do nothing and can be deleted from code
+    - `worker.initialize` and `worker.loadLanguage` functions should be deleted from code
