[Laszlo-dev] release note for 'implicit this'

[Donald Anderson]

Lou, can you add this as a release note or update the doc as you see  
fit?
Tucker, can you review this?  This is related to LPP-7965.

Before 4.2.1, attributes created in code were allowed to be freely  
used without a 'this' qualifier.
For example this code was allowed:
      this.myattr = "hello";
      var something = myattr;   // 'this.myattr' is implied

In 4.2.1, this is no longer supported.  The programmer has two  
choices.  The preferred approach is
to declare the attribute in question using <attribute/>, like so:

      <attribute name="myattr" type="string" />

An alternative would be to explicitly use 'this' in all usages:

      this.myattr = "hello";
      var something = this.myattr;

The old behavior is still allowed for SWF8 and DHTML runtimes, but may  
be marked deprecated in the future.
