|
|
|
* Any changes to virtual modifiers get propagated properly.

|
|
|
|
|

|
|

being the following: OY, ()), =<, =^, and =v.
|

|
* Avoids a crash when the X connection gets broken while closing down.

|
|
|

|
|
|
to 1.7:
|
|
|
|
|
|
|
|
|
|
|
|
* XSetIOErrorExitHandler which provides a mechanism for applications
|
|
|
|
|
|
to recover from I/O error conditions instead of being forced to
|
|

|
exit. Thanks to Carlos Garnacho for this.

these.

|
|

and improvements.

|
Savolainen for this.
|

|
|
|
|
|
|
|
|
|
|
* Allowing use of 'v' for caron, in addition to 'c', so things like

|
