# Finding Firmware Files

Firmware releases can be found at ceruleansonar.com >> products >> \[your product type].

DVLs and ROVLs may have comprehensive release packages that include a README file describing the included files and any special information, plus recent changes included in the software and firmware. An example release directory is shown below. See [ROVL Firmware Files by Device Type](/c/ceruleantracker/installing-firmware/rovl-firmware-files-by-device-type.md)for help in deciding which ROVL files are needed for your device(s). DVL releases are similar except the firmware files are the same for all versions of DVL.

{% hint style="info" %}
If you have an internet connection and your version of CeruleanTracker is later than November 1, 2022, then you can use CeruleanTracker to automatically find firmware, decide if it is newer than your installed firmware, and install the new firmware. See [Updating Firmware in a Functioning Device](/c/ceruleantracker/installing-firmware/updating-firmware-in-a-functioning-device.md) for details.
