The latest bugs fixed in the Advanced Maths Library and related files:

Date: 31/5/97

• The Advanced Maths Library:

• 1. Changed the export method so that exporting the functions from the DLL is easier. Also a user of the DLL is less likely to accidentally get incorrect linkage.

• The Maths Test Utility:

• 1. Separated out a lot of the functionality (relating to the maths mappings) in the Test Utility to another DLL. This is to allow for future re-use of the DLL's functionality into more products.
  2. IMPORTANT: New test file format. All test files created prior to the release date of 28/3/97 will not be recognised. Please contact me if you require the test file to be converted.

• The Test Files:

• 1. Need to re-run the test suite due to the changes in the Advanced Maths Library.

Go back to download the software.

Date: 29/5/97

• The Advanced Maths Library:

• 1. Recompiled under MSVC++ v5.0 . This required considerable re-juggling of function definitions.
  2. Sped up some of the functions, especially for Intel based releases (builds with _80X86 defined).
  3. Placed all of the Advanced Maths Library functions, structures, classes, etc, etc into it's own namespace.
  4. Renamed the Advanced Maths Library's power function from "pow_aml" to "pow", as the function is no longer in the global namespace and thus doesn't conflict with standard the 'C' "pow" function.

• The Maths Test Utility:

• 1. Recompiled under MSVC++ v5.0 .
  2. IMPORTANT: New test file format. All test files created prior to the release date of 28/3/97 will not be recognised. Please contact me if you require the test file to be converted.

• The Test Files:

• 1. Need to re-run the test suite due to the changes in the Advanced Maths Library.

Date: 13/4/97

• Added a ZIP file comment giving details about the archive's contents and contact information.

• The Advanced Maths Library:

• 1. None.

• The Maths Test Utility:

• 1. Fixed the "Stop" button on the tool bar, so that it now actually works (!).
  2. Added a status pane to the Test File View windows, so that the maths or sequence testing status is shown.
  3. IMPORTANT: New test file format. All test files created prior to the release date of 28/3/97 will not be recognised. Please contact me if you require the test file to be converted.

• The Test Files:

• 1. Added ZIP file comment about the contents of the ZIP file, what utility should be used with the files, copyright notice and contact info.

Date: 5/4/97

• The Advanced Maths Library:

• 1. None.

• The Maths Test Utility:

• 1. Fixed a bug that caused the "Test It" button in the Maths Mappings Browser to be greyed, even if test files were still open, when a test file was closed.
  2. IMPORTANT: New test file format. All test files created prior to the release date of 28/3/97 will not be recognised. Please contact me if you require the test file to be converted.

• The Test Files:

• 1. None.

Date: 28/3/97

• The Advanced Maths Library:

• 1. Added a random number generator and tested it.
  2. Corrected the n-vector string parsing function.
  3. Corrected some other n-vector and pxq matrix mappings.
  4. Updated the Advanced Maths Library Help document with the random number mapping. Updated the list of (known!) bugs in the Maths Test Utility and Advanced Maths Library. Added documentation of the "Pre-run Test Files" archive.
  5. Fixed the factorial function - it was overflowing and returning invalid results.
  6. Updated the list of bugs for both the test utility and library in the Advanced Maths Library Help document.

• The Maths Test Utility:

• 1. More user interface improvements: Status pane added to the Test File View windows so that the current position is shown in a test (including during testing). Also the View updates to show the current test being tested in a sequence test.
  2. Corrected the DLL Test code, and added some ASSERTs (which don't appear in the release alpha) to remind me that some of the maths mappings still don't work.
  3. Added the random number test to the mappings list in the Maths Mappings Browser.
  4. Corrected a bug that caused the date and time in the test file not to be set when the related test is run.
  5. Improved the checking for the same calculated result as the supplied one. Now if a test is repeated, all of the calculated results must be the same as the supplied value, not just the last calculated result.
  6. IMPORTANT: New test file format. All test files created prior to this release date will not be recognised. Please contact me if you require the test file to be converted.

• The Test Files:

• 1. Added a random number test file.
  2. Updated the DLL Test File, due to corrections and additions to the DLL Test code (above).
  3. Updated all of the test files to the new format; see above.
  4. Updated the factorial test file.
  5. All of the test files have been re-run to check the Advanced Maths Library, as the last time they were run was some time ago, and many changes have since occurred.

  3. Removed the ability to read old version test files.
  4. Better version information displayed in the "About" dialog.
  5. Introduced a bug in freeing allocated memory, so that the Maths Test Utility throws a (seemingly harmless, but annoying) exception just after it closes.

• The Test Files:

• 1. All test files have been converted to the new format. - It reads and saves faster, is more compact, and allows up to1024 tests per file - please contact me if more tests per file are needed.

Go back to download the software.

Date: 13/1/98

• 1. Updated program and help to reflect new ISP details.

Go back to download the software.

Date: 13/12/97

• 1. Fixed a bug when the mouse cursor passed near the top left hand corner of the ruler, Mez Sure minimised and showed the close dialog box.

Date: 12/12/97

• 1. Fixed the bug where the contents of Mez Sure were increasingly offset if the rotator tool was not snapped to the centre of Mez Sure, and it was used to rotate Mez Sure.
  2. The rotator tool now appears in the correct place when Mez Sure is first opened.
  3. The rotator snaps to the corners of Mez Sure correctly.
  4. Mez Sure rotates about the rotator correctly, when it is snapped to a position in Mez Sure.
  5. Fixed a bug: when attempting to close Mez Sure, but with the rotator tool window active caused a crash.
  6. Minor performance enhancements, including running in 256 colour mode with a custom background.
  7. Fixed an error in the details windows that meant that even when the dialog informed the user of incorrect values, they were applied to Mez Sure when the "Apply" buttons were pressed.
  8. Enhancement: Clicking on the spin control buttons for the number of tick marks dynamically updates the number of tick marks.
  9. Fixed a bug where the centre of the ruler was increasingly displaced when the ruler is resized.

Date: 4/10/97

• 1. Improved the performance of the custom window shaped buttons. They now pop up & down better & more responsively.
  2. Dramatically improved the dragging of Mez Sure and the rotator tool. They now follow the mouse, no matter how fast the mouse is moved!
  3. More optimisations regarding the drawing of Mez Sure.
  4. Added a control to enable/disable full window drag. Enabling full window drag makes it much easier to reposition Mez Sure.
  5. Fixed the redrawing of Mez Sure when system colours are changed, so that Mez Sure updates itself immediately and correctly.
  6. Fixed bugs in the nudge step edit boxes and angle step edit box relating to when the units are changed and the values in the edit boxes are incorrectly changed. This lead to incorrect values being used to alter Mez Sure.

Date: 18/9/97

• 1. The scale on Mez Sure has problems when used with virtual desktops - if the viewport size is changed (via changing the viewport resolution) then the scale has to be manually changed to compensate. Added a control to allow this, see below.
  2. Mez Sure's scale was wrong at resolutions other than 1024x768. Fixed this and allowed dynamic rescaling if the screen's resolution is changed on the fly.
  3. Fixed a bug in Mez Sure when starting: if a saved background bitmap could not be found, it hung.
  4. Improved the way a custom background is displayed if the screen colour depth is changed on the fly. Though there is a problem that you have to click on Mez Sure to get it to update the custom background's palette.

Date: 28/8/97

• 1. "Rotator" windows still buggy - Mez Sure's window furniture is now drawn in the correct place, but the Mez Sure window is not.
  2. Added tool tips for the custom buttons. But the tool tips don't appear when the mouse is over the animation in the "rotator" buttons.
  3. Transparency is still buggy.
  4. More minor optimisations and corrections to the re-drawing code.
  5. Added "Tips" extension panels to the two details windows to help guide user's in some of the functionality of Mez Sure. Slightly improved & prettied up the dialogs.
  6. Fixed incorrect colours appearing in 256 colour bitmaps when used as backgrounds on 256 colour displays.
  7. Hopefully allowed custom backgrounds to appear under Windows NT.
  8. Improved the user interface. Added drag and drop of background BMP's into Mez Sure for changing the background bitmap.

Date: 15/8/97

• 1. Corrected a bug in custom tiled backgrounds. Tiling failed at angles>10degrees.
  2. Some minor optimisations in redrawing.
  3. Added two buttons to allow increasing or decreasing the length of Mez Sure.
  4. "Rotator" windows still buggy.
  5. Transparency is still buggy.
  6. Updated the Help documentation to reflect current credits and new icon (see below).
  7. Added resizing buttons.
  8. Fixed access violations in GDI32.DLL .

Date: 9/8/97

• 1. Made a permanent fix to dragging Mez Sure so that you can see an outline. Also it repaints properly.
  2. Corrected a few bugs in the installation. Also updated it for the new features in Mez Sure.
  3. Corrected non-opening help file.
  4. Improved the Mez Sure's icon. Thanks to Patricia Riebandt for the basis of the new design.
  5. Added a number of features, such as improved unit selection and setting angles in degrees or radians. Also the ability to change the number of minor ticks per major tick.
  6. Innumerable minor optimisations.
  7. Fixed problems that occurred when moving Mez Sure with the mouse, then losing it, then trying to get back to it.
  8. Added the "rotator" buttons. This allows Mez Sure to be rotated about any point on th screen. Note: this has a number of bugs in it.
  9. Transparency is still buggy.

Date: 31/7/97

• 1. Quick fix to Mez Sure not repainting properly.
  2. Fixed moving Mez Sure off the left or top of the screen.
  3. Fixed a few problems in the installation - one of which had the tick border the same colour as the tick mark itself. This caused the tick marks to look wider than they should.
  4. Fixed a nasty resource leak that spewed USER memory wantonly all over the place.

Date: 29/7/97.

• 1. This is a first beta release ~ there are a number of known intractable bugs in the transparent mode of operation.

The latest bugs fixed in Aleph One:

Date: 5/1/2000

1. Fixed restoring PNGs that were created by Aleph One. There was some code I missed out in the Aleph One modified LIBPNG that I should have put in when I updated the LIBPNG code. Oops!
2. Corrected the creation code for the non-primary render engines on multi-processor machines. They were created as primary render engines, therefore having unnecessary extra code in them.
3. Fixed switching to the Julia-type from the Mandelbrot-type when using the mouse to select the index of the Julia-type from the Mandelbrot-type
4. Added ability to have arbitrary natural powers for mapping the scale in the colour range. This is handy for things like continuous potential colouring schemes on Julia sets.
5. Fixed an error where the co-ordinates of the render engines were not reset when the fractal’s co-ordinates were changed.
6. Prevented changing to the partner-type when showing orbits, or from showing orbits when choosing the partner index. Or choosing the partner index whilst tracing orbits or such-like.
7. Improved zooming in and out when entering the magnification factor directly.

Date: 28/11/1999

1. The under sampling level is reset when the colour range is modified.
2. When screen updates are occurring the status bar reflects this in case a "hang" occurs during updating the screen.
3. Added a "percentage done" indicator to the status bar when reading or writing athe fractal in PNG format.
4. Corrected a problem when resetting a fractal and when changing to a different number system when a fractal is being rendered.
5. Fixed saving and restoring over sampled fractals.
6. Fixed generating over sampled fractals.
7. Added an indicator so that when the over sampling level is being set, the user has an indication of the memory load they are creating. (It's easy to get carried away.)

Date: 14/11/1999

• 1. First release.

The latest bugs fixed in Ultimate System Timer:

Date: 25/10/97

• 1. More performance enhancements.

     • Operating Systems - it should now work without problems on Windows NT and Windows 95.
     • Cross platform portability - greater use of C++ language elements to reduce reliance on MSVC++ specific features, such as using __int64 types as opposed to ULARGE_INTEGER.

Date: 29/5/97

• 1. Turns off all compiler optimisations around the functions that access the RDTSC instruction on the processor due to run-time errors in MSVC++ v5.0 .

Date: 16/3/97
