In Maple 2024, using commands like 
with(LinearAlgebra):
M := Matrix([[1, 2, 3, 10], [4, 15, 6, 7], [0, 0, 0, 0]]);
ReducedRowEchelonForm(M);

we see output of the 3x4 matrices fine at first, but when I and my students try to print or save to a PDF, ellipsis (three dots) sometimes show up in the bottom row. I checked the settings for elision and they are as usual. This is only when trying to print---the ellipsis show up in both the Maple file and the printed copy. We've tested on both Mac and PC. This did not happen in Maple 2023.

I have side-by-side comparisons in an image below: the Maple looking fine before we try to print or save as a PDF, what happens in the Maple file after with the bottom row, and the elision settings. Any help would be greatly appreciated as we would like the full matrices to show up in printing or a PDF we save to.

I’m on a Mac running Ventura 13.4.1 and Maple 2022. 

My plots now have axes and labels that are tiny. It seems like that possibly happened with one of the recent OS updates
Below is a graph of
with(plots): implicitplot3d(3x+2y+4z=2);

It renders the same if I use 
implicitplot3d(3x+2y+4z=2, axesfont=["TimesNewRoman", 12], labelfont = ["TimesNewRoman", 12]);

I can to change the 12 to much larger to see them. But I never used to have to do that before. Does anyone know if this is an OS issue? Is there a global setting I can change? 

I'm having an issue with MacOS Big Sur 11.4 recognizing a package from saved documents. The package works great from new documents! 

Specifically: 
I've followed the instructions on 
https://www.maplesoft.com/support/help/Maple/view.aspx?path=worksheet/reference/initialization
to add  a .mapleinit
file to my user home directory under MacOS Big Sur 11.4

The .mapleinit file has code as follows to run the VLA package: 
VLAlibpath := "/VLA/library/":
libname := `VLAlibpath`, libname:
and I have the VLA package files with the library inside of it in my home directory too. 

When I open a new Maple document and run and use the package, it works just fine! 

The problem though is that if I save the Maple file and reopen it, it will no longer recognizes the package. I get: 
Error, invalid input: with expects its 1st argument, pname, to be of type {`module`, package}, but received VLA

It is very odd since the file still recognizes the libname just fine:
libname;   "VLA/library/", "/Library/Frameworks/Maple.framework/Versions/2021/lib"

The workaround is to copy and paste into a new document and start a fresh but that is obviously not ideal. 

Any ideas? It is a really really old package, but great for visualization.

Thanks,
Sarah
