Version 3.1, January 23, 2008

3.1 fixes a number of bugs (see the Bug list) and adds a few nice new features.

Enhancements

• added elseif.

  $if(x)$...$elseif(y)$...$else$...$endif$

  See Conditionally included subtemplates
• added format option. See Object rendering#Format Option
• updated group.g and eval.g so that list literals can have empty atoms like

  $["a",,"b"]:{n | ...}; null="nullstring"$

• Caleb Lyness revamped entire TestStringTemplate to run under windows.
• Added 16 bit char unit test.
• Allows unicode escapes as expression literals but only if it's the whole
  expression: <\uFEA5\n\u00C2> Previously could only do one char and just
  the special ones like <\n>.

Bug fixes

• ST.dup() was not copying renderers field.
• _ was not allowed in group/interface.g but in group.g. Now _ is allowed as first char.
• John Snyders submitted a bug fix for length() and for format option. Renderer was being for string expr options
• Thomas Brandon pointed out that we have a bug in our if/else computation. You could not reference super.attr inside the if/else sub templates.
• i0 was not set when you applied a template to a single value.
• ST-18 fixed. put close in a finally block.
• "default" as a key (the string not keyword) was not a valid value in map. I had testLiterals looking even at strings in lexer for group.g. Fixes ST-15.
• Property "getters" that return arrays were not converted to internal data structures necessary for ST to iterate over those elements.
• Made convertArrayToList create an ArrayWrappedInList so it doesn't copy arrays any more.
• Updated group.g to allow default clause by itself in map (from Caleb Lyness)
• reader was not closed in PathGroupLoader.
• $first(list).prop$ was not allowed. Fixed and added a unit test.
