+
+Bug fixes:
+
+* VIM-676 Handle control characters in `.ideavimrc` as pressed, not typed
+  keystrokes
+* VIM-679 Parse characters less than U+0020 as `<C-$CHAR>`
+* VIM-683 Allow `<C-PageUp>`/`<C-PagDown>` to be used outside of Vim emulation
+* VIM-646 Don't update the visual selection if a command moves the caret and exits
+  the visual mode
+* VIM-213 Use `'<` and `'>` marks for saving and restoring the last visual
+  selection
+
+
+0.34, 2014-04-29
