0013 ### 2.4.2
0014
0015 #### Behavior changes
0016 - `jana:max_inflight_events` now defaults `nthreads` regardless of whether `nthreads` was explicitly set. Previously it defaulted to 4 when `nthreads` was unset, and otherwise defaulted to `nthreads`. (Issue #443)
0017 - `JEventSource::GetEventCount()` is deprecated and replaced by `GetSkippedCount()`, `GetEmittedEventCount()`, and `GetProcessedEventCount()`. These behave intuitively when `nskip` is used. (Issue #428)
0018
0019 #### Features
0020 - Added `jana:output_processed_event_numbers` parameter to assist with debugging (Issue #425)
0021 - Ported `janaroot` plugin from JANA1
0022 - JFactory detects and excepts on cycles (Issue #423)
0023 - Improved scale test visualizations, including plotting multiple scaling tests on the same plot and supporting log scaled axes.
0024
0025 #### Bugfixes
0026 - Missing template argument in VariadicPodioOutput
0027 - JEvent was being marked as warmed up prematurely
0028 - JAutoactivator was being called last instead of first (Issue #440)
0029 - If the user attempted to run without providing a JEventSource, processing would crash with an ArithmeticException instead of a helpful error message (Issue #437)
0030 - `JEventSource::FinishEvent()` was being called spuriously (Issue #424)
0031
0032 #### Refactoring
0033 - 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)
0034
0035 ### 2.4.1
0036
0037 This release enables CCDB caching, significantly improving performance and reducing memory usage for applications that frequently access calibration constants.

0079 ### 2.3.2
0080 This release includes the following:
0081
0082 #### Features
0083 - Added a simple `JWiringService` which can be used to wire `JOmniFactories` via a TOML file. (#353, #363)
0084 - Added `add_jana_plugin`, `add_jana_library`, and `add_jana_test` CMake macros (#364)
0085
0086 #### Bugfixes
0087 - A multithreading bug in `JEventProcessor` has been fixed.
0088 - `JFactory::Create` now checks `JEventSource::GetObjects` (#361)
0089 - `JPluginLoader` no longer loads plugins twice in certain cases (#343)
0090 - `JParameterManager::FilterParameters` marks parameters as 'used', thereby avoiding spurious 'unused parameter' warnings. (#331)
0091 - `JTypeInfo::to_string_with_si_prefix` generates the correct SI prefix in certain cases (#348)
0092
0093 #### Refactoring
0094 - Plugins and their headers are now installed to a directory that doesn't conflict with a system install (#330)
0095 - `JPluginLoader` has been extensively rewritten (#339)
0096 - `JCsvWriter` has been moved into `examples` (#350)
0097 - JANA's internal performance testing RNG has been refactored to be more reproducible, and to avoid ASAN violations. (#315)
0098 - `JPodioExample` has been split into several reusable examples. (#352)
0099 - Code was moved from `Omni` and `Status` into `Components`, making the layered architecture clearer (#351)
0100 - Documentation has been overhauled, including adding an extensive JANA1-to-JANA2 migration guide (#334, #336, #342, #354, #357, #359)
0101 - CI testing has been extended (#332, #341)
0102
0103 #### Behavior changes:
0104 - JANA now has one internal logger, configurable via the `jana:loglevel` parameter. External loggers are now configurable via the `jana:global_loglevel` parameter.
0105 - Log output has been streamlined: oversized tables are now YAML, and essential information is now logged at `WARN` level. (#362)
0106 - `JPluginLoader` now stops when a plugin fails to load, rather than continuing searching for another plugin with the same name.
0107 - `JPluginLoader` no longer accepts paths as part of a valid plugin name
0108 - `JFactorySet` is no longer silent when the user attempts to include duplicates of the same factory (#343)
0109 - `JMetadata` is deprecated, to be replaced with `JMultifactory`. (#345)
0110 - All `JFactories` now call `JEventSource::GetObjects`, not just `JGetObjectsFactory`. (#361)
