Valery,
As you know, I intend to continue my work to fix/improve the tensor
packages. I have not done anything since the 5.9.1 release because I want to
wait until the downcasing is complete and the code has stabilized.
Is anyone else planning to make any changes to share/tensor? Wolfgang, I
believe, mentioned that he may be doing work on the share packages,
including the tensor package. This is why I don't want to be doing anything
just yet, while things are still in motion.
I also noticed a problem when I downloaded the latest CVS: ctensr.mac now
fails because the command APPLY is no longer recognized. I haven't
investigated this yet, just noticed the problem last night. Worked fine in
CVS just a few days earlier.

Subject: Re: [Maxima] Case-sensitivity patches now in CVS
I have checked the downcased tensor package with last cvs update.
It is need some additional work to bring tensor to working state. All
covariant indices now are printed in upper case (even they are defined in
low
case) while contravariant one go in low case.
Also it does not work if I issue "bothcases:false"
In this case maxima complain even about simple construction
