+---------------------------- History -----------------------------
+
+Version 5.1   25-Mar-99
+
+  * Symmetry of the number 8 improved.
+
+  * Curvature of tilde exagerated to prevent it from looking
+    like a straight line at low point sizes.
+
+------------------------------------------------------------------
+
+Version 5.0   16-Feb-99
+
+   * Several character shapes have been changed to improve
+     distinctiveness and legibility.
+
+   * All character outlines have been made more precise
+     and uniform, resulting in better on-screen legibility
+     and consistency (i.e. improved "color").
+
+   * The hints for every character have been reviewed and
+     improved. Because the font does not use delta hints,
+     however, it's on-screen appearance is not quite as good
+     at low point sizes as fonts that do.
+
+   * Direct support for bold, oblique, and bold oblique
+     family members has been dropped. The shapes calculated by
+     the rasterizer look better.
+
+------------------------------------------------------------------
+
+Version 4.0   11-Dec-97
+
+   * The on-screen appearance has been improved considerably.
+
+   * Characters are slightly (about 2%) narrower, allowing
+     more characters per line.
+
+   * MS-DOS graphics characters have been added. As a result
+     the character keymap has changed somewhat. The keycodes
+     for the standard characters has not changed, but the
+     keycodes of special characters such as '(c)' (copyright)
+     have changed.
+
+------------------------------------------------------------------
+
+Version 3.0   24-Jan-97
+
+   * Fixed a problem with the attributes of the oblique
+     family members.
+
+------------------------------------------------------------------
+
+Version 2.0   5-May-96
+
+   * The entire font family (regular, oblique, bold, and
+     bold oblique is supported.
+   * The weight of the font has been made considerably
+     more uniform.
+   * Character shapes have been tweaked for a better
+     screen appearance.
+   * Additional character positions have been filled to
+     prevent problems with desktop publishing applications.
+
+------------------------------------------------------------------
+
+Version 1.0   3-Oct-95
+
+   * Origination
+
