Oh great. I didn't even get a full day's use out of 4.12.6!

Thanks for the heads up.

I did get ~33 hours on 4.4.81

But this is definitely unusual -- the mean time between each of the 82 linux-4.4.x releases has been just over 7 days.

The 4.4.82 release is definitely out of band ...

# script date2int - count days since 1899-12-31

For the most part, this batch appears to be fixing regressions.

For developers who tangle with Embedded Linux periodically,
where does one find a list of the Linux Kernel features
which have changed since the well-documented 2.6 release ?
Is there a good URL or new book series documenting these
later versions ?

Boy, howdy !

I would love to see such a Document or book.

Being an old fart^H^H^H^Hcodger, I felt like I understood the 2.6.x kernels pretty well ( about as well as an application developer needed to understand the Kernel

)

Anyhow, there is so much churn with the current Kernel Development Model, not to mention BIOS-vs-uEFI and on, and on, I imagine a dead-tree-based book would be a losing proposition ...

It would be obsoleted before the ink dried on the paper ( more likely before ink was even applied to paper ) !

I did find this file: /usr/src/linux/Documentation/Changes which in addition to spelling out mimimal requirements for the 3.0 Kernels, it also lists a few Major Architectural changes in the 3.0 Kernel.

Anyhow, I don't see any other obvious file in the Kernel Tree relating to *_ALL_* the changes since the 2.6.x series.

Maybe Jonathan Corbet or another author at lwn.net has written one-or-more articles that describe what "we're" after ( https://lwn.net/Search/DoSearch ) ?

I've not waded thru the list myself but lwn.net can be a great learning resource.

HTH.

It's not authoritative, but the following may give you some clues:

Sorry for the delay in dusk, it turns out that I ****ed up the permissions on /tmp doing something else a couple of days ago

Linux 4.9.45 is running good here!
