October 14, 2004 - Version 0.80 Released

It's been two months and three week since the launch of Open Math Edit. I must say, I didn't believe there would be almost 2400 downloads. Even though I can't tell how many people use it, it's still a positive indicator though.

Due to a dispute with another organization, Open Math Edit is now Mathcast Equation Editor or just MathCast.

This version is more complete and usable, and it adds the important feature of matrices. Enjoy.

Here is the change log:

  • Matrices support.
  • Documentation updated and revised, some new sections added.
  • Embedded Mozilla is now 1.7.3.
  • MathCast now built with GCC 3.4.2.

  • A few small Rapid Mathline errors corrected. Blocks are now accesible through Ctrl+9 and Ctrl+0.
  • Exporting to .BMP and .PNG bug fixed.
  • Some small bugs were fixed.

I'd like to thank Dror Schwartz and Chen Rabiner for thier bug reports, feature requests, and advice.

July 23, 2004 - Open Math Edit Released

After months of hard work, Open Math Edit version 0.75 is released, along with the launch of this website.
The goals I've set for this version have been met, and thus this release is stable and usable.

It is my hope that this software will be helpful to many people, who will use it in their studies, their work or for other reasons, both in the direct sense and the indirect sense, by visiting websites or reading documents that feature Mathematics created with the assistance of Open Math Edit.

I don't know how many people will use this software or whether or not it'll be successful. Enjoy.
