I started this history with Euler 1.50. Note that the version numbers are inconsistent with the OS/2 version, which is no longer maintained.
1.73 |
Fixed a strange bug in the Windows version of Euler (related to breaks in castled loops). |
1.71 |
Fixed a bug in shuffle. |
|
Euler can now call an external editor, which can be chosen in a separater dialog. |
1.70 |
Fixed a bug in copying, saving and printing, which caused the current window to become empty. |
|
Wrote a notebook for boundary value problems, and a file to test a Newton barrier method. |
1.69 |
Fixed a bug in bitmap output, when the size is not the window size. Background was not deleted. |
1.68 |
Improved the demos and the help command. |
|
Utility files were missing in 1.67. |
1.67 |
Fixed a bug from version 1.61 in copying and printing (thanks to Werner Heid). |
|
Some changes in the 3D functions to improve usability. New functions are f3d, f3daxis, f3dpolar, f3daxispolar. |
|
Utility files (loaded from euler.cfg at Euler start) are now in a subdirectory progs/util to avoid accidental changes. |
1.66 |
Improved the wait function. It does no longer check keys for times less than 1 sec, but simply sleeps. This removes a bug in animations. |
1.65 |
User plots now map to functions. |
|
Bug in animation demo under Windows XP removed. |
1.64 |
Fixed a bug in normal(), which is due to a compiler bug in Visual C++. |
|
The internal editor is now larger and works differently. Loaded or saved file names are remembered and used instead of the default $$$$.e. |
1.63 |
Font for the internal editor is now the same as the text window font. |
1.62 |
Euler is now compiled using Visual C++. |
1.61 |
Improved key presses to stop animations. |
Use coprocessor interrupts to detect floating point errors. This should be faster. | |
Graphics now clip to the drawing area. New functions are clip and unclip. | |
1.60 |
Improved animations. |
Worked on the documentation. | |
1.59 |
New Version for Linux |
Reworked the documentation, examples and overview. |
|
1.58 |
Fixed the project function |
New 3D functions mark3, framedmark3 |
|
New function stereo for stereo plots |
|
1.57 |

|
1.56 |
Improved solid 3D |
Removed triangles (now default) |
|
1.55 |
Fixed an error with the file name, when saving the internal editor file |
Wrote shiftleft, shiftright, rotleft and rotright |
|
1.54 |
Global strings can now be changed, when the lenght is shorter |
End key now prints "endfunction" only on empty line in function editor |
|
