The default colors used by the Student subpackages have changed. By default, the colors used by the Student subpackages are now from the CVD color palette.  You can change the colors using Student:-SetColors. To get the default colors used in Maple 2022 and earlier, use the following:

Student:-SetColors("Niagara");

Improvements to contour and density plots include the following:

The default colors used by contour plots and density plots have changed.

A color bar is shown beside the plot.  You can turn this off using colorbar=false.

Density plots now use a finer grid and no patchlines by default. The older style can be obtained using style=patch.

The default colors used for the lines in DEplot have changed.

The GAMMA function now evaluates for larger postive integers using the factorial form. Previously, $\mathrm{\Gamma }\left(101\right)$ returned unevaluated and had to be explicitely expanded. Now GAMMA automatically expands for all integer values less than $100001$.

In response to customer requests, when you use Tools > Load Package, the command is now visible in your document.

Certain commands are not currently available on machines with Apple Silicon CPUs while running native binaries.  A list of these commands is found on the Platform Specific Issues help page.  If you run into this issue, in order to use these commands, use the Intel x86-64 version of Maple, found under /Applications/Maple 2023.
