 LIST OF CHANGES 
 
-by which this package tikz-feynhand (Version 1.0.0 of 2018/01/31) 
+by which this package tikz-feynhand (Version 1.1.0 of 2019/08/19) 
 which is available at https://ctan.org/pkg/tikz-feynhand
 
-was obtained from the original package tikz-feynman (Version 1.1.0 of 2016/02/05)
-which is available at https://ctan.org/pkg/tikz-feynman
+was obtained from Version 1.0.0
 
 ==========================================================================
 
-The LICENSE has been changed from LPPL to GNU General Public Licence v3.
-
-The changes are rather minor:
-any reference to LuaTex has been removed,
-the definitions that are unnecessary 
-for manual diagram creation have been removed,
-and some drawing styles have been added.
-
-In general, I REPLACED each occurence of the string "feynman" by "feynhand", 
-in order to avoid clashes when both packages are loaded simultaneously, 
-and most of these replacements are NOT listed individually below.
-Apart from that, the list below contains all changes to the best of my knowledge.
-
-The files tikzfeynman.patch.3.0.0.lua and tikzfeynman.patch.3.0.1.lua
-of the original package are not contained in the modified package,
-neither is the documentation of the original package.
-
-All file names and line numbers below refer to 
-the files of the original package tikz-feynman (Version 1.1.0 of 2016/02/05).
+All file names and line numbers below refer to the files of Version 1.1.0.
