Seriously...
LITERALLY my verbatim response to the Telegraph notification!
I've updated the patches.

So... what changed?
Essentially nothing. It's possible there were a few minor changes in the code itself (e.g. numbers, math operations), but I haven't had a chance to look at that yet.
You mean you don't want the dictionary problems that you extensively described fixed?

The only purpose of this release is to fix the issues with "prefix_exceptions" in the dictionary.


Update:
For my usual release comments see my post in the 4.24.15672 release thread.

With the addition that calibre version 5 was also released today. This includes support for the 4.24.x firmware versions. But, if you are a MAC user, there is a bug recognising any ereader. There should be an update in a couple of days.
I didn't look at the dictionary stuff specifically (those kinds of changes which only affect individual instructions in existing functions are the hardest to notice, and I would have overlooked this too since it's almost be too good to be true to have that fixed so quickly). But yes, I did want those fixed if it was possible and if it was actually an issue rather than not using it correctly (after all, I did figure everything out based on the assembly and some educated guesses for relevant test cases, since there aren't yet any available official v3 dictionaries using prefix_exceptions). In that case, I'm quite pleased with Kobo.

Thanks for the pointer about what changed. It'll save me a lot of time, both for figuring out what changed, and for when I test dictionaries expecting it to do the same thing. Remember that I'm looking at a disassembly, not the original source code, and that doesn't cleanly diff or do things in the most logical manner.



I think this will become my favourite release so far, as almost everything I've personally wanted fixed in the firmware has now been fixed, and I haven't discovered any major issues/regressions with the features I use so far.

Edit: I'll look through the code again and post a more details summary of the changes when I have time (either tomorrow night or two days after that).

Edit 1: I just took a quick peek at the most likely places, and I think I've found the changes. I'll come up with test cases later.

Edit 2: For anyone interested, the most important part is at 0x5a61ac in 15672 and 0x5a643c in 15676. I'll also need to debug one of my scripts, since it should have noticed a side effect of this change automatically.

Edit 3: The bug was in my parsing of the JSON diff of the output of one of my tools (it didn't detect single-character changes properly).

Edit 4: I can confirm this fixes the default behavior for my main test cases . That's all I'm going to check for today. Tomorrow, I'll look at exactly how it does it and what changed.
Just chiming it for another kudos on the update, the crappy^Wsupbar English dictionaries were basically one of my last gripe with the Kobo software for an ex-Kindle user, so, yay \o/.
