This release fixes a couple subtle bugs, but most importantly, it adds time rounding and coalescing.
With rounding enabled, when you create a new invoice or estimate, each labour item taken from a task will have its duration rounded according to the selected rounding rule (configured from Preferences).
With coalescing enabled, after a task is stopped, the adjacent time entries are merged into one if the time distance between them is less than the configured cut-off. If you also enable dropping short tasks, then when a task is stopped it will be deleted if the duration is less than the configured cut-off.
