Release Notes: This release adds minor bugfixes and adds a new optimization algorithm (a preconditioned CCSA variant).
Release Notes: Various minor bugfixes.
Release Notes: Various fixes to compile under Microsoft Visual Studio, as well a bugfix to absolute tolerance settings.
Release Notes: The SLSQP algorithm was added for gradient-based nonlinearly constrained optimization. Implicit per-dimension scaling is done in BOBYQA and COBYLA. Various bugs were fixed.
Release Notes: Minor bugfixes and a slightly more natural Python API for vector-valued constraints.
Release Notes: This release corrects a configure check for Python include directories, missing version functions in the Guile interface.
Release Notes: Support for vector-valued constraints. Nonlinear equality constraints in the COBYLA algorithm.
Release Notes: A new object-style extensible interface, nonlinear equality constraints, and new interfaces for C++, Python, and GNU Guile.
Release Notes: This release adds Powell's BOBYQA algorithm (box-constrained sequential quadratic programming without derivatives) and the ISRES evolutionary algorithm (nonlinearly constrained optimization). There are minor installation fixes.
