24-Jan-2009 017 I was looking over some pages casually and spotted a typo.

19-Jul-2007 56 One of the browser snap-shots on this page was incorrect.
16-Jul-2007 218 Fixed problems with World menu and halos access in deployed image. Added a blank initial grid condition and unit test.

13-Jul-2007 214 Show the developer how to create a stand-alone application in OS X for our Laser Game written in Squeak. This section is Mac OS X specific.
12-Jul-2007 208 Completed the first pass at a deliverable application. It's still comprised of a Squeak VM and dedicated image file, and not enough of the development environment features are disabled yet, but it's a good start.
12-Jul-2007 18 Added another note to advise the reader if they are unable to find their test case in the Test Runner window.
10-Jul-2007 Introduction 15A

There's some new text in the Introduction section explaining how the tutorial begins with more browser screen-shots and why I'm doing that.

I've received a number of e-mails from programmers new to Smalltalk and/or Squeak that have made the mistake of creating their first test case class as a subclass of Object instead of TestCase. To help the reader not make that mistake I added a note to the page to ensure they did this step correctly. On that same page I also added more description and a visual for how the new method category is created.

06-Jul-2007 205 - 207 Wrote some preliminary code to support stand-alone application delivery.
07-Jul-2007 Notes

Changed the Workspace description for launching LaserGame morph now that version 20 was released.

Also changed the links for the packages to always point to a gerneric named package. The Mac OS X Unix scripts I'm using to backup and publish this tutorial now create these to avoid problems where I forget to update the file names for latest release packages.

Changed layout of "Notes" within the tutorial to be separate sections for each category (Packages, History, Comments).

06-Jul-2007 56 Forgot to include the source for the #offsetWithinGridForm on the CellRenderer class.
06-Jul-2007 15, 200 - 204

Corrections of typos and other errors, based upon user feedback. (NOTE: I'm placing comments in the HTML as possible to identify anyone who helps).

Also reworked the minor enhancements into a group of pages and added another enhancement for default LaserGame morph size.

06-Jul-2007 index Tweaked the colors of the Index page to tone it down a bit.
