+
+        Revert the previous change of comint-line-beginning-position callers,
+        and modify comint-line-beginning-position instead.
+
+        * comint.el (comint-history-isearch-search)
+        (comint-history-isearch-message, comint-history-isearch-wrap):
+        Use comint-line-beginning-position instead of field-beginning.
+        (comint-send-input): Use either end-of-line or field-end
+        depending on comint-use-prompt-regexp.
+        (comint-line-beginning-position): Search backward
+        for comint-prompt-regexp if comint-use-prompt-regexp is non-nil.
+        Use field-beginning instead of line-beginning-position
+        if comint-use-prompt-regexp is nil.  (Bug#19710)
+
+2015-03-03  Robert Pluim  <rpluim@gmail.com>  (tiny change)
+
+        * calendar/todo-mode.el (todo-item-done): When done items are
+        hidden, restore point to its location prior to invoking this
+        command.  (Bug#19727)
+
+2015-03-03  Eli Zaretskii  <eliz@gnu.org>
+
+        * textmodes/artist.el (artist-ellipse-compute-fill-info): Use
+        mapcar, not mapc, to create the other half of fill-info.
+        (Bug#19763)
