I have updated the modem.zip file to the latest modem firmware of Fairphone OS 17.09.3. This zip file also includes the official Fairphone splash image. In case you have installed a custom splash image, you might want to reflash it.
I wanted to add some verification code to the updater-script, but it doesn’t run yet. I’ll try to fix it until the next release.

After you have flashed the zip file, you should see the version 4437.1-FP2-0-07 under Settings -> About Phone -> Baseband Version. It was 4436.1-FP2-0-05 in the previous version.
Since those are binary blobs, I have no idea what has changed since the previous release. But comparing the image files, I can see that the following files were changed:
NON-HLOS.bin
rpm.mbn
sbl1.mbn
tz.mbn
The following files were not changed since previous release:
splash.img
emmc_appsboot.mbn
sdi.mbn
Alternatively, you can flash the latest modem firmware using fastboot. You can get the firmware images from the official Fairphone OS downloads page (scroll down to binary images). Don’t flash system.img, boot.img and recovery.img obviously.
