13.1.2.2: Version 2.10.0 [2002 May 20: Victoria Day]

• In the documentation, change the names of some variables to be clearer: `ll_x' is now written `xleft', etc.

• Add RPN binary operators `and', `or' for logical operations see Binary Operators, along with negation operator `not' see Unary Operators.

• Add `draw arc' command (see Draw Arc).

• Add `set x axis labels' (see Set X Axis) and `set y axis labels' (see Set Y Axis) commands.

• Permit specification of `pt' units for `draw label' (see Draw Label), `draw box' (see Draw Box), `draw symbol at' (see Draw Symbol At), and `draw line from' (see Draw Line From).

• Add `set clip to curve' (see Set Clip) command. Caution: this needs extension, and may have a bug if called twice in succession [but is this with an intervening `set clip off']

• Add `group' and `end group' commands, in preparation for SVG output. So far these commands do nothing, and are basically just a signal that users should not create commands with these names since Gri will need them soon.

• Add `..xinc..' and `..yinc..' builtin variables (see Axis Scaling).

• Make the `open' command accept URLs as filenames (see Open).

Removed Features

• Remove `gri -repair old.ps new.ps' since (a) it was only half functional, (b) it was hard to code in the new scheme of argument-processing and (c) the author was not aware of anybody every having used it.

• Make the `-chatty' commandline option require a value (see Invoking Gri).

Bug Fixes

• Fix SourceForge bug #552009 (`rpn' can segfault if `!=' operator is written as `=!')

• Fix SourceForge bug #546109 (bounding box wrong if postscript clipping used)

• Fix SourceForge bug #514495 in which `set clip to curve' failed to handle missing values in the curve.

• Fix SourceForge bug #450465 (`create columns from function' was broken).
