 * Extra optional input :code:`args` which passes through arguments for :code:`objfun` (pull request from `logangrado <https://github.com/logangrado>`_).
 * Bug fixes: default parameters for reduced initialization cost regime, returning correct value from safety steps, retrieving dependencies during installation.
 
-Version 1.1a0 (17 Jul 2018)
+Version 1.1 (24 Dec 2018)
 ---------------------------
 * Extra parameters to control the trust region radius over multiple restarts, designed for global optimization.
 * New input flag :code:`seek_global_minimum` to set sensible default parameters for global optimization. New example script to demonstrate this functionality.
 * Bug fix: default trust region radius when scaling variables within bounds.

 <p>Py-BOBYQA is a flexible package for finding local solutions to nonlinear, nonconvex minimization problems (with optional bound constraints), without requiring any derivatives of the objective. Py-BOBYQA is a Python implementation of the <a class="reference external" href="http://mat.uc.pt/~zhang/software.html#powell_software">BOBYQA</a> solver by Powell (documentation <a class="reference external" href="http://www.damtp.cam.ac.uk/user/na/NA_papers/NA2009_06.pdf">here</a>). It is particularly useful when evaluations of the objective function are expensive and/or noisy.</p>

 * Extra optional input :code:`args` which passes through arguments for :code:`objfun` (pull request from `logangrado <https://github.com/logangrado>`_).
 * Bug fixes: default parameters for reduced initialization cost regime, returning correct value from safety steps, retrieving dependencies during installation.
 
-Version 1.1a0 (17 Jul 2018)
+Version 1.1 (24 Dec 2018)
 ---------------------------
 * Extra parameters to control the trust region radius over multiple restarts, designed for global optimization.
 * New input flag :code:`seek_global_minimum` to set sensible default parameters for global optimization. New example script to demonstrate this functionality.
 * Bug fix: default trust region radius when scaling variables within bounds.
