I took the plunge and updated my KO3 from firmware 5.16.2.1.1 to the newly released 5.17.1, and it seems I am not able to get the jailbreak back following Marek's instructions for HF firmwares. I installed the non-HF hotfix and installed the 5.17.1 update, however I am unable to successfully run the HF hotfix to complete the procedure.

I'm not asking for help (I was aware of the risk when I ran the update), I just wanted to give a heads-up to anyone potentially planning on updating their Kindle that the new update might not play nice with their jailbreak for now.

Some more details:

Uploading the Update_jailbreak_hotfix_1.16.N_khf_install.bin file to the root of the Kindle does not bring up an "invalid update file" error when ejecting the Kindle, however attempting to install it from the Kindle UI results in an error message saying that a problem occurred and the update failed.
Uploading the Update_KUALBooklet_hotfix_f190a38_install.bin file to the root of the Kindle does bring the "invalid update file" error. The other KUAL .bin files (install and uninstall) don't register as update files (no update menu item shows up).
Trying to install the hotfix via ;log mrpi doesn't work - MRPI won't start (the Kindle just actually searches for the string in the books). I made sure to have Marek's updated MRPI binaries for HF installed in the extensions folder, but I believe those require a working KUAL.
;log runme also doesn't work, either with the downgrade script or for the emergency-bridge-recovery script.
;711 however does work, so it doesn't seem that all ";" commands were disabled.
