Main changes over 1.0.0.beta1:

• Updated QDLDL to 0.1.8.
• OSQP can now be compiled for wasm32. Look for some sample notebooks on this soon.
• Updated documentation and examples at https://osqp.org

libosqp - v1.0.0.beta0

First beta release of OSQP v1.0

New features:

• Introduced new linear algebra backend system allowing compute framework to be changed at compile time.
• Merged cuOSQP project into main OSQP project (inside algebra/cuda directory).
• Introduced an Intel MKL-based algebra backend using the MKL sparse BLAS API, Vector Math Library. This backend contains both the Pardiso solver and an RCI conjugate gradient implementation.
• Added code generation capabilities to the C-level API (note, only problem export is in the C API, no file copying is done).
• Added initial adjoint derivative computation to the C-level API.

Main changes:

• Updated QDLDL to 0.1.7.
• Changed QDLDL to be included through CMake FetchContent instead of a git submodule.
• The MKL Pardiso solver is only available with the MKL backend.
• CMake installs CMake config files for consuming applications to use.
• All of OSQP's API is contained inside the public include files (there should be no need for users to include anything in private).
• All OSQP functions, defines and types are prefixed with OSQP (in some capitalization) to namespace the API.

Developer-centric changes:

• Test suite switched to Catch2 and now incorporates modern C++ for memory management and organization.
• ASAN flags integrated into main OSQP CMake build system.

libosqp - 0.6.0

• Added meaningful return values to internal functions. Changed syntax of osqp_setup function. It now returns an exitflag.
• osqp_setup function requires P to be upper triangular. It returns a nonzero exitflag otherwise.
• Custom memory allocators via cmake and the configure file.
• Changed interfaces to linsys solver functions. The solve function now computes (x_tilde,z_tilde) instead of (x_tilde,nu). This allows to implement custom linear system solvers (also indirect).
• Added solve function in Python interface that performs setup solve and cleanup for you directly and disables GIL.
• Improved code generation folder structure.

libosqp - 0.3.0

Features * Added time_limit option * Added CUTEst interface * Add "install" CMake target and installation of CMake configuration files

Interface changes * Changed set_default_settings to osqp_set_default_settings and brought function to main API header osqp.h * Allow eps_rel=0 #40

Bugs * Fixed bug in upper triangular P extraction. Now the solver can accept both complete P matrix or just the upper triangular part. * Fixed #33 * Fixed #34 * Fixed bug when calling osqp_solve or osqp_cleanup after failed linear system initialization * Fixed potential name conflict with SCS 47 * Fixed #49
