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

New Features

- 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).
