• consume #19 #20: the syntax for offsets has changed. The goal is to be more explicit and more flexible. Special values are now denoted by strings, rather than negative values: all to refer to all partitions, newest to refer to the newest available offset of a partition and oldest for the oldest offset respectively. Partitions are now separated by = and start and end offsets by :. For example: all=1:10 to consume messages between offsets 1 and 10 (both sides inclusive) for all partitions. This syntax change allows for relative offset definitions either to skip messages since the oldest offset (e.g. +10), or refer to messages before the newest offset (e.g. -10). Please see kt consume -help for more information. This change is not backwards-compatible.
• consume: The partitions are now consumed in parallel right after they are identified to decrease initial delay.
• topic #20: The names for oldest and newest offset when -partition is specified are now consistent with the names used for consume.
• topic #22: To improve feedback time, the topic information is now read and printed in parallel. This change breaks backwards compatibility as the output is not guaranteed to be sorted anymore (sort should be your friend here).
• kt #21: kt -help now prints build version and time information when built via make.
