Well ... that was unexpected.

Here's another new AntS1 binary.

The comment I made about the last version having Temperature Management in it was wrong.
Oops.

I did enable the flag in the code (which doesn't work in Bitmain's version) but I didn't realise there was no code using the flag until someone pointed it out to me later.
In fact 7 of the 8 options passed to the Bitmain code are ignored:
bitmain_temp, bitmain_overheat, bitmain_fan_min, bitmain_fan_max, bitmain_freq_min, bitmain_freq_max and bitmain_auto

Anyway, this new binary DOES have Temperature Management code in it that I've written and tested for 24 hours now on all 3 of my ants.
It takes notice of bitmain_temp and bitmain_overheat

It uses the same patch as before for the luci display.
My source for this version is here:
https://github.com/kanoi/cgminer/tree/ants1-4.2.0-c85d846a

The binary and README are in my cgminer-binaries git here:
https://github.com/kanoi/cgminer-binaries/tree/master/AntS1  <-- Follow this link to get the new binary

Read the README on the screen there for how to replace the /usr/bin/cgminer binary in your AntS1 with the new one.

This binary includes all cgminer changes up to 4.2.0 and forward after that up to:
https://github.com/ckolivas/cgminer/commit/4e05c30bfa12d658253ea670995156e069fdb5f0

The specific AntS1 changes this time really does include:
Perform temperature management (it doesn't work in the Bitmain code)

I have had one person report that they cannot run the binary.
I've no idea why - since others have had no trouble running yesterdays binary.
If you cannot run this binary please let me know.
I'm chasing up someone with literally hundreds of ants and hoping they'll use it and get expected results.
