I think it clarified some text in the WiFi settings about known networks.

The patches of the earlier firmware seem to work with this without any hiccups.

Without having to install them again, you mean?

No, you still have to reinstall them just like before. They just work the same as they did on the older software.

FYI. Unusually, the nickel and librmsdk.so.1.0.0 files in fw 4.38.23697 versus fw 4.38.23684 are binary equal. Therefore any patches in nickel.yaml/librmsdk.so.1.0.0.yaml should not need any updates.

The 2 libnickel.so.1.0.0 files are not binary equal so I'm less certain about libnickel.so.1.0.0.yaml patches. Nevertheless all of the patches I actually use worked without updates.

I'll have a go at my usual test which is my patches. Then I'll see what other libnickel.so.1.0.0 patches are left to test.

Thank you for this. It helps.

Would you mind doing the same thing for 4.45.23697? Thanks.

I will but not here. I don't want to confuse anyone by mixing up details about two different firmwares, 4.38.xxxxx/4.45.xxxxx in the same post.

I'll PM you.

Anecdotally (and it the absence of release notes for 4.38.23697) it feels to me as if my Libra 2, when used with the Kobo Remote, is not suffering from quite as bad a battery drain as it did with previous firmware.

I'd be interested to know if anybody else finds this.

It could be, analysing the .tar.gz there is a new firmware for the Bluetooth chip of the Libra 2.

One oddity on Patrick Gaskin's Kobo Firmware Download site, it still shows 4.38.23684 for the Touch A/B/C, Kobo Glo, Kobo Aura and Kobo Touch 2.0. Yet, other Kobo4 (i.e. Kobo Aura HD), Kobo5 (i.e. Kobo Aura H2O) and Kobo6 (i.e. Kobo Aura ONE) hardware devices show 4.38.23697 as being available. The Touch A/B Kobo3 devices do not appear to have a 4.38.23697 version available

I tried downloading the new firmware for the Kobo 3 devices and it's not happening. So maybe that's it for them.
