find changesets by author, revision, files, or words in the commit message
1)
Изменён формат имени diff-файлов.
Теперь в имени присутствует только название сессии, время и имя файла.

2)
Можно просмотреть отдельную сессию.
Для этого нужно щёлкнуть по блоку сессии в журнале

3)
Исправлена ошибка с таблицей новых команд в последнем дне.
Раньше она просто не показывалась

4)
Запись lablog-ов теперь ведётся только для интерактивных shell'ов
Неинтерактивные работают как обычно.
