Does anyone know what this means?

From the release Notes for Second Life 1.17.2(0) June 27, 2007
=====================================
LSL changes:
* Added support for alternate sculptie edge stitching.
* VWR-68: LSL constant expression folding and proper constant parsing

Can someone translate that from Lindenism to semi-english for me?

When specifying PRIM_TYPE_SCULPT for PRIM_TYPE in a llSetPrimitiveParameters list, the following topology (or "edge stitching" types can now be used:

PRIM_SCULPT_TYPE_TORUS (left stitches to right, top stitches to bottom)
PRIM_SCULPT_TYPE_CYLINDER (left stitches to right)
PRIM_SCULPT_TYPE_PLANE (no edge stitching)


Not a frakkin' clue.

I read VWR-68 at https://jira.secondlife.com/browse/VWR-68 and it seems to be two things: a bug in the parsing of negative constants has been fixed, and constant expressions like '3 * 5' or '-PI_BY_TWO' are calculated at compile time instead of computed using byte codes when your program is run.

Yes, its used to be if you said:

integer x = 5-3;

you would get a compile error, as the parser saw it as:

integer x = 5 -3; // two numbers one positive one negative.

you had to insert a space to get it to compile, like so:

integer x = 5 - 3;
