# History:
#
+# 2018-04-10, Sébastien Helleu <flashcode@flashtux.org>
+# version 0.8.1: fix infolist_time for WeeChat >= 2.2 (WeeChat returns a long
+# integer instead of a string)
+#
+# 2017-09-20, mickael9
+# version 0.8:
+# * use weechat 1.5+ api for background processing (old method was unsafe and buggy)
+# * add timeout_secs setting (was previously hardcoded to 5 mins)
+#
+# 2017-07-23, Sébastien Helleu <flashcode@flashtux.org>
+# version 0.7.8: fix modulo by zero when nick is empty string
+#
+# 2016-06-23, mickael9
+# version 0.7.7: fix get_home function
+#
+# 2015-11-26
+# version 0.7.6: fix a typo
+#
# 2015-01-31, Nicd-
# version 0.7.5:
# '~' is now expaned to the home directory in the log file path so
