What's new in version 0.7.1
|
||||
|
||||
* Add support for Linux per-process IO statistics,
|
||||
enabled with the --enable-taskstats flag, which
|
||||
requires a kernel compiled with taskstats support.
|
||||
(thanks to Tobias Oetiker)
|
||||
* Add Unicode support, enabled with the --enable-unicode
|
||||
flag, which requires libncursesw.
|
||||
(thanks to Sergej Pupykin)
