 ## 1.3.0 (2023-12-22)
 A big swath of bug fixes and improvements. The highlights certainly are fixes and conveniences around saved benchmarks and loading them again via the new `Benchee.report/1`. The other big one is saving a lot of memory (and time!) when processing big inputs. Sadly the latter comes with some breaking changes for plugins, but they are well justified and shouldn't actually affect any plugin in practice.

 ### Features (User Facing)
 * System information now includes whether or not the JIT is enabled ([erlang docs](https://www.erlang.org/doc/apps/erts/beamasm)).
 * Benchee now let's you know when it's calculating statistics or running the formatters. Helps when you wonder what's taking so long or blows up memory.
