This is a log of changes that ncurses has gone through since Zeyd started
working with Pavel Curtis' original work, pcurses, in 1992.
Changes through 1.9.9e are recorded by Zeyd M Ben-Halim.
Changes since 1.9.9e are recorded by Thomas E Dickey.
Contributors include those who have provided patches (even small ones), as well
as those who provide useful information (bug reports, analyses). Changes with
no cited author are the work of Thomas E Dickey (TD).
A few contributors may be cited in this file by their initials.
Each accounts for half of one percent or more of the changes since 1.9.9e.
See the AUTHORS file for the corresponding full names.
