New version of RGraph: version 7.21

It's release day! Happy release day everyone! A new version of RGraph is now available to you - version 7.21 - from the download page.

There aren't a great deal of changes in this version - in fact the only significant change has been to the Modal Dialog which has been rewritten from the ground up.

The prior version was originally written many years ago so the best way to bring it up to date was to rewrite it from scratch.

This facilitated the use of modern techniques and improved reliability, compatibility and speed. Plus, it made it easy to add new features.

In terms of new features, there are new effects and animations, easier ways to customise the dialog to your needs and one significant addition - the ModalDialog.confirm function.

This new function serves as a replacement for the built-in alert, confirm and prompt functions and allows you to prompt the user with significantly prettier dialog boxes than the alert/confirm/prompt functions allow for. The OK and Cancel buttons call functions (which are defined by you, of course) when they're pressed thus allowing you to control the path of the user through your application.

Read the documentation page about the Modal Dialog and see examples of using it here.
