This is a pro forma release to turn on [Zenodo automatic versioned DOIs.](https://guides.github.com/activities/citable-code/).

For new functionality added since 1.0.3, consult the [1.0.4 Release Notes](https://github.com/pysal/spreg/releases/tag/v1.0.4).

We closed a total of 16 issues (enhancements and bug fixes) through 7 pull requests, since our last release on 2018-05-11.

Main Release Enhancements.

This release adds additional estimators and tests for [seemingly-unrelated regression](https://en.wikipedia.org/wiki/Seemingly_unrelated_regressions) models with endogenous spatial lag & spatial error structures. These methods in `spreg.SURerrorGM`, and `spreg.SURerrorML` have also been extended to incorporate spatial regimes regression.

Issues Closed
- Libpysal refresh (11)
- update docstrings for libpysal API changes (9)
- Merging in spanel & spreg2 code necessary for new spatial panel & GeoDaSpace (10)
- move to silence_warnings from current libpysal (7)
- add init to ensure tests are shipped (6)
- weights typechecking will only accept things from `pysal`. (3)
- relax error checking in check_weights (4)
- simplify testing (5)
- Convert spreg to common subset 2,3 code (2)
