# Change log for esp-sr

## Known issues: 
- Available storage is less than the remaining flash space on IDF v5.0.   
If you can not map model partition successfully, please check the left free storage by `spi_flash_mmap_get_free_pages(ESP_PARTITION_MMAP_DATA)` or update IDF to v5.1 or later.

## 1.4.2
