LavaPE

The user interface of the Lava Programming Environment LavaPE and of the Lava interpreter is no longer based on the MDI (Multiple Document Interface) concept but on tabbed and splitter widgets, which provide more neatly arranged, non-overlapping windows. The state/value object distinction has been slightly revised once more. "Virtual types" may be declared "final" now. Lava has been ported to Mac OS.

This release turns Lava into a language that completely prevents inadvertent access to uninitialized variables and null objects at programming time by complete static initialization checks. The new optional initialize clause of the declare construct will facilitate the creation/initialization of collections of Lava objects with mutual/circular/forward references. The semi-automatic Lava GUI generator allows you to assign event handlers to certain basic GUI events.

This release supports further Unix platforms. Event handling by callbacks has been completely revised. Class Object provides a new "recursive zombify" method. The NullSoft NSIS installer is used now for the binary Windows version. The build process allows you to benefit from GCC precompiled headers.

The Lava debugger now also displays the "self" object and the function/operator parameters on entry and exit to or from a function/operator. WhatsThis and WhatNext context-related help was further extended.

This is a bure bugfix release related to the new debugging support functions.
