Version 1.6.1 (2020-09-13)
--------------------------
- Unpinned ``numba`` from version 0.48. Version 0.49 `changed the seed <https://numba.pydata.org/numba-doc/latest/release-notes.html#version-0-49-0-apr-16-2020>`__ used for ``np.random.choice()``, meaning that results from versions >=0.49 will differ from versions <=0.48. Version 0.49 was also significantly slower for some operations, which is why the switch was not made at the time, but this no longer appears to impact Covasim.
-- *Regression information*: No changes to the Covasim codebase were made; however, No major backwards incompatibilities are introduced by this version. Instances of ``sim.compute_summary()`` should be replaced by ``sim.summarize()``, and results dependent on the original state of an intervention post-simulation should use ``sim._orig_pars['interventions']`` (or perform ``sim.initialize()`` prior to using them) instead of ``sim['interventions']``.

+- *Regression information*: No changes to the Covasim codebase were made; however, new installations of Covasim (or if you update Numba manually) will have a different random number stream. To return previous results, use the previous version of Numba: ``pip install numba==0.48.0``.
