Hi Maxim,
I'm glad to see that you care about documentation. Way to go! Here is a
couple of points that can help:
1) I think it's safe to assume that Prachi will not work on the Ignite
documentation any longer. You can take up the issues assigned to her and
prioritize them whichever way is convenient for yourself. In fact, you
can take up other's issues as well.
2) I'll try to do my best to finish as much documentation issues as I'll
be able to by the release date.
So, it looks like that in general we are good.

Ilya,
I agree that issues related to `documentation` can be safely
postponed, however, for me the whole batch of such issues looks
unmanageable and unclear. At least we should prioritize all of them to
complete the maximum that we can by the deadline.

Hello!
I think that Documentation tickets may be safely postponed until final
stages of release, since it's not included in artifacts, rather available
on readme.io, etc.

Igniters,
Who can advise what we can\should do with the issues related to
`documentation` component to release Ignite 2.8 version?
How can I sort them and prioritize?
What are best-practices here?
Currently, we have 81 issues pinned to 2.8 release [1].
6 - `In Progress`
2 - `Patch Available`
73 - `Open`
Some of the issues are assigned to the `Prachi Garg` which is not
active since February 15-th 2019.

Can we decouple Tensorflow from the IGFS?

Igniters,
It's true that we are still discussing the release dates.
But
nevertheless, all the release blockers are important since
some
of
them may require more than one month to be fixed. Let's
discuss
today
how we will handle these issues and track Monitoring and ML
major
features to get them into the next release.
The meeting already scheduled. We will use the ASF Slack on
September
25-th, 17-00 (MSK).
I've created the channel [2] #ignite-release-2_8 please,
join.
(Discussion will be on Russin language).
Please, also note that I've created the 2.8 release
confluence
page
[1] with additional information. I will review all the
issues we
have
and will move some of them to 2.9.
But currently, we've had pinned to 2.8:
- 604 open issues
- 57 in progress issues
- 34 patch available issues
- 17 issues marked as the release blockers
- 4 of release blocker issues are unassigned

Hi Igniters,
I suppose discussion is still at phase 0-Initializing

So it is probably no reason to discuss particular

would make
sense when the process of removal irrelevant tickets
starts
(phase

and
till phase 4-Release candidate building.
