alice-teacher New Alice 2 and Alice 3 Versions

[Romero, Chris]

Hello Eric.

Thanks so much for the continued support of Alice 2.x

When launching the new 2.5.4 version, I am prompted to install DirectPlay. A brief read on DirectPlay from Wikipedia has me concerned about its "deprecated" nature and the network connections it wants to make. Is it needed?

Thanks for your time,
Chris

Dear All,

I wanted to let everyone know that we have released a new version of both Alice 2 and Alice 3.  Most critically the new Alice 2  version resolves our High Sierra problem allowing Alice 2 to function properly on the news Mac OS.  There are general performance and stability improvements for both version as well as some bug fixes that we think will make a lot of you and your students work a lot easier such as fixing the issue where shape objects were constantly reseting when you ran your program in Alice 3.  Please keep telling us what you need and the problems you are finding so we can continue to make the systems better.  Thank you all again for all of your support and patience.

Sincerely,

Eric
