17 | Temporary note: | |
18 | +++ indicates that the appropriate manual has already been updated. | |
19 | --- means no change in the manuals is called for. | |
20 | When you add a new item, please add it without either +++ or --- | |
21 | so we will look at it and add it to the manual. | |

35 | * Changes in Emacs 23.1 |
36 | ||
37 | ** If the gpm mouse server is running and t-mouse-mode enabled, Emacs uses a | |
38 | Unix socket in a GNU/Linux console to talk to server, rather than faking events | |
39 | using the client program mev. This C level approach provides mouse | |
40 | highlighting, and help echoing in the minibuffer. | |
41 | ||

42 | ** The new variable next-error-recenter specifies how next-error should |
43 | recenter the visited source file. Its value can be a number (for example, | |
44 | 0 for top line, -1 for bottom line), or nil for no recentering. | |
