Hello Hans,

my step-by-step actions:

1. Updated ConTeXt yesterday - described before.

2. Created EnvHome.mkiv for testing:

----
\starttext
   Ahoj
   \ctxlua{print("1",environment.homedir)}
   \ctxlua{print("2",environment.oldhome)}
   \ctxlua{print("3",os.getenv("HOME"))}
   \ctxlua{print("4",os.getenv("USERPROFILE"))}
\stoptext
----

3. Opened console and launched:

----

PATH=d:\Ctx-Beta\tex\texmf-mswin\bin;%PATH%

d:\Lukas\ConTeXt\Test\EnvHome>echo %HOME%

3. So, logged:

"
system          > ConTeXt  ver: 2020.01.30 14:13 MKIV beta  fmt:

2       nil
3       C:/Users/u×ivatel
4       C:/Users/u×ivatel
"

4. I also didn't find any "oldhome" text using fulltext search in 
ConTeXt installation directory.

Did I updated ConTeXt correctly?
