+## 3.64.4
+**`(fix):`** Fix additionalProperties in examples being lost when a schema defines `additionalProperties: true`. Previously, additional properties in examples were set to undefined during conversion, causing them to be stripped from the output. Now the actual values from the example are preserved.

 ## 3.64.3
 **`(fix):`** Fix extraction of large generated ZIP files (>2 GiB) by using the `yauzl-promise` library instead of the `decompress` library. Node.js has a 2 GiB limit for reading files into buffers, which caused the `decompress` library to fail with `ERR_FS_FILE_TOO_LARGE` errors for large SDK outputs. The `yauzl-promise` library streams ZIP entries individually instead of loading the entire file into memory.
