https://devzone.nordicsemi.com/f/nordic-q-a/106432/how-to-add-a-version-to-an-application-build-for-mcubootHi, How do you add a version number to the image header when it&#39;s being signed? I can only find this config which seems to have been removed in release 2.5.0.

According to the <a href="https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/releases_and_maturity/migration/migration_guide_2.5.html">migration guides for nRF Connect SDK 2.5.0</a>:</p> <p>Applications using MCUboot must update to setting their version using an <a title="(in Zephyr Project v3.4.99)" href="https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/zephyr/build/version/index.html#app-version-details"><span>application VERSION file</span></a> instead of the previously used <code><span>CONFIG_MCUBOOT_IMAGE_VERSION</span></code> Kconfig option. Alternatively, you can set the version in Kconfig by using the <a title="(in Kconfig reference v&amp;nbsp;)" href="https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/kconfig/index.html#CONFIG_MCUBOOT_IMGTOOL_SIGN_VERSION"><code><span>CONFIG_MCUBOOT_IMGTOOL_SIGN_VERSION</span></code></a> option, but using a <code><span>VERSION</span></code> file is the recommended approach.</p> <p>Regards,<br />Terje</p><div style="clear:both;"></div>
