Where's Leela?

Where was I on the Leela series? My previous post, The Lineage of Leela (11 June 2018), was a filler. I spent my time on that post browsing the Leela forum, trying to understand more about the Leela technology. In the post before that, Understanding Leela (04 June 2018), I promised,

There are also many technical threads that discuss different configurations for the Leela client or that delve into the structure of the network(s). Let's look at those another time.'

The top of the main project page, LCZero, currently has an undated message that says,

Net has been replaced with a new bootstrap net with 50 move rule normalization and learnable batch normalization beta bias. It will likely be weaker to start but will hopefully grow stronger quickly.

What does that mean? Maybe I'd better retrace my steps, because it looks like I missed something. I'll start by looking at the links on LCZero's left sidebar (in order).

*** Getting Started: This goes to

Home · glinscott/leela-chess Wiki · GitHub

That page says, 'A.O. edited this page 11 days ago · 26 revisions; Moved to https://github.com/LeelaChessZero/lc0/wiki'

Welcome to the Leela Chess Zero wiki!

That page looks like the instructions I followed for Installing Leela (21 May 2018), so at least I'm on familiar ground.

*** Forum: This also looks familiar. The link goes to:-

LCZero - Google Groups

The top of that page says, 'This forum is for all the discussion about LCZero - https://github.com/glinscott/leela-chess'. That github.com page says,

GitHub - glinscott/leela-chess: **MOVED TO https://github.com/LeelaChessZero/leela-chess ** A chess adaption of GCP's Leela Zero

Following that link leads to:-

GitHub - LeelaChessZero/lczero: A chess adaption of GCP's Leela Zero

Note that the 'leela-chess' has redirected to 'lczero'. The main github.com page is:-

LCZero · GitHub

*** Github: This leads to the same page that I just looked at: github.com/LeelaChessZero/.

*** Networks: After more internal links -- 'Matches', 'Active Users', etc. -- there is another external link...

*** LCZero Chat: Here under #dev-log, I found the same message that is on LCZero's main page: 'Net has been replaced with a new bootstrap net [...]'. Signed, Chad - 10/06/2018.

Where's Leela? The main Github page has moved, but the rest remains as before. The chat looks to be a preliminary source of technical discussion to the forum.
