v2.4.2

Behavior changes

• jana:max_inflight_events now defaults to nthreads regardless of whether nthreads was explicitly set. Previously it defaulted to 4 when nthreads was unset, and otherwise defaulted to nthreads. (Issue #443)
• JEventSource::GetEventCount() is deprecated and replaced by GetSkippedCount(), GetEmittedEventCount(), and GetProcessedEventCount(). These behave intuitively when nskip is used. (Issue #428)

Features

• Added jana:output_processed_event_numbers parameter to assist with debugging (Issue #425)
• Ported janaroot plugin from JANA1
• JFactory detects and excepts on cycles (Issue #423)
• Improved scale test visualizations, including plotting multiple scaling tests on the same plot and supporting log scaled axes.

Bugfixes

• Missing template argument in VariadicPodioOutput
• JEvent was being marked as warmed up prematurely
• JAutoactivator was being called last instead of first (Issue #440)
• If the user attempted to run without providing a JEventSource, processing would crash with an ArithmeticException instead of a helpful error message (Issue #437)
• JEventSource::FinishEvent() was being called spuriously (Issue #424)

Refactoring

• Preliminary support for random-access JEventSources is provided via JEventSource::Skip(). This feature should be considered experimental for now because it doesn't work with barrier events yet. (Issue #422)
