Changes in version 1.0.2.9000                      

                 Changes in version 1.0.2 (2023-09-09)                  

  - Fixes a bug in how the package documentation was specified.
  - ompr.roi now requires at least R 3.5.0 because ompr requires it.

                 Changes in version 1.0.1 (2022-09-05)                  

  - ompr.roi does not use a deprecated {Matrix} 1.4-2 function anymore.

                 Changes in version 1.0.0 (2022-01-27)                  

  - ompr.roi is now licensed MIT.
  - LazyData was removed from the DESCRIPTION file as is produced a CRAN
    warning.
  - ROI's status and message information are now part of the returned
    solution and can be accessed calling additional_solver_output() on
    the returned value.

Breaking changes

  - In line with ROI's way of encoding a general termination status, the
    solver_status(result) is now "success" if ROI returned code = 0,
    otherwise it is "error".

                 Changes in version 0.8.0 (2018-06-11)                  

Breaking changes

  - The package exports column and row duals of LPs. Extracting duals
    might be solver dependent. Only tested with GLPK. This requires
    version 0.8 of ompr.
  - Minimum supported R version is 3.4.0 since slam also requires >= 3.4

New features

  - ompr.roi works with other ompr backends as well.
  - ompr.roi always returns a solution, even if the solution status is
    not optimal. It extracts the ROI solution with force=TRUE.

                 Changes in version 0.7.0 (2017-11-18)                  

Major breaking changes

  - The package uses the new sparse matrix interface of ompr and ROI.
  - Minimum supported R version is now 3.3.0

Minor changes

  - as_ROI_model exports an 'ompr' model to ROI::OP Github Issue #9

                 Changes in version 0.6.1 (2017-10-23)                  

Bugfix

  - Fixed a bug where the ROI::V_bound object was incorrectly
    initialised. This causes an error with ROI >= 0.3.0.

                 Changes in version 0.6.0 (2017-04-19)                  

  - First release on CRAN
