docs say it's internal but not when done. i no longer have a .m to read definitions of what's in it

?*`CRTlist does show it still exists

but when called it does not evaluate as it had. i have no .m to know why

a notebook of mine uses this to show "crtwo" (among other improvements) solves chinese remainder showing ALL repeated solutions but the old ChineseRemainder ("by stan wagon et al") could not do it

while crtwo itself is un-effected, the notebook describing "crtwo" is now needs repair.

it is not a simple notebook. such repairs are not 1-2-3. i really wish they hadn't done that. i'll be finding tons of needless (wonton) hackery makng my notebooks fail for days - and have time to fix a precious few - which has been delayed by talking about it.

really: how do i use pre-v11 notebooks with 11. that's the question.

what is broken between them isn't really the question (though newly sometimes undocumented)

Is there a package i can load that makes running older notebooks easier?

am i missing something? that's my question. what i don't know :)

How do I run pre-Mathematica 11 Notebooks in Mathematica 11? Or 11 in 12?

As said by Ilian, Sphere is now a built-in that produces a smooth sphere without specifying rendering-related parameters. Also ChineseRemainder is now a built-in function (since V6 I think). No need to load any package. I think many of the functions you used before in V4 are now part of built-in function which are more convenient and most likely faster. Of course you can (down)load these packages again but be wary of naming-conflicts.

If you don't want to leverage the functions of versions 5,6,7,8,9,10,11 and still use the old functions in packages, then you could just as well use V4...

It will take some effort to convert some of the package-functions to built-in functions...

In[1]:= ?Sphere Sphere[(r:1, (n:20r, m:15r))] is a list of n*(m-2)+2 polygons approximating a sphere with radius r.

Needs["Miscellaneous`Units"] $Fails

but Needs["Units`"] works

This is a nuisance change - helping some hacker but hurting everyone who used Units in a notebook - which i HOPE is everyone.

It was difficult to find what worked because Mathematica 11 documentation does not say when the change occured nor tell me what package to load. Also (for iMac), the .m files are all gone so i cannot research the answer for myself - i'm left with using Kernel Evaluation to guess/find where SI units are to be found. however for other changes documentation DOES show where to go and what the deciding $VersionNumber is to use.

again i don't like having other decide my job is to sit around re-writing what already works - to make their life simpler

Incorrect Sphere was introduced before version 4.0

You should be able to run all your stuff since version 1 of Mathematica in the new Mathematica 11.

If you share some code that 'does not work' in V11 but did in V10 we could assess the situation a bit better.
