-- [#580](https://github.com/kpdecker/jsdiff/pull/580) Multiple tweaks to `diffSentences`:
+- [#580](https://github.com/kpdecker/jsdiff/pull/580) **Multiple tweaks to `diffSentences`**:
   * tokenization no longer takes quadratic time on pathological inputs (reported as a ReDOS vulnerability by Snyk); is now linear instead
   * the final sentence in the string is now handled the same by the tokenizer regardless of whether it has a trailing punctuation mark or not. (Previously, "foo. bar." tokenized to `["foo.", " ", "bar."]` but "foo. bar" tokenized to `["foo.", " bar"]` - i.e. whether the space between sentences was treated as a separate token depended upon whether the final sentence had trailing punctuation or not. This was arbitrary and surprising; it is no longer the case.)
   * in a string that starts with a sentence end, like "! hello.", the "!" is now treated as a separate sentence
   * the README now correctly documents the tokenization behaviour (it was wrong before)
-- [#581](https://github.com/kpdecker/jsdiff/pull/581) - fix some regex operations used for tokenization in `diffWords` taking O(n^2) time in pathological cases
+- [#581](https://github.com/kpdecker/jsdiff/pull/581) - **fixed some regex operations used for tokenization in `diffWords` taking O(n^2) time** in pathological cases
+- [#595](https://github.com/kpdecker/jsdiff/pull/595) - **fixed a crash in patch creation functions when handling a single hunk consisting of a very large number (e.g. >130k) of lines**. (This was caused by spreading indefinitely-large arrays to `.push()` using `.apply` or the spread operator and hitting the JS-implementation-specific limit on the maximum number of arguments to a function, as shown at https://stackoverflow.com/a/56809779/1709587; thus the exact threshold to hit the error will depend on the environment in which you were running JsDiff.)
