stockfish - new patch code update

I guessed Oct. 2nd version had 33 elo boost up

but that patch (which acquired 33 elo increase) was not applied to the code yet

I guess that date indication doesn't mean the version number of the engine, but the date indicates when the new code was tested

so the patch (or the new code) which contains 33 elo boost will be applied for the future version of the engine

when do you think the new patch (with 33 elo up) will be applied and will be in effect?  

from the 3 illustrations

I can take a guess on what that means

it is my guess that
+38 elo was gained for
SF Oct 8th
and that new version of SF engine
was released on the same day

so when a new version is tested
ppl don't have to wait for many days
that version can be released on the same day

***

I thought that 38 elo gain happend
from the previous version
(so I thought the Oct 8 is 38 elo stronger than Oct 7)
but I think
that doesn't mean that

it is my guess work that
that 38 elo gain is from the base engine

I think
base means SF 4 or SF 3
after the release of official SF4
the base means the official SF4 version
it is my guess

and master means
the latest developmental version of the engine
it is my guess

and it seems working out well
if SF Oct 8 is 38 elo stronger than the official SF4
then it makes a good sense!

I found out something more that is of more importance!

when we compare the 1st post in this thread
(2 posts above)
and the 2nd post in this thread
(1 post above)


Oct 2
elo of 33.9 is higher than the base (presumably SF 4)

Oct 8
elo of 38.9 is higher than the base (presumably SF 4)


so from SF Oct 2 to SF Oct 8
it is an opinion that
I think there was the elo gain of 6 points!
and that's something incredible!
