It provides a flexible interface for\nbuilding and solving conservation planning problems. Once\nbuilt, conservation planning problems can be solved using a\nvariety of commercial and open-source exact algorithm solvers.\nBy using exact algorithm solvers, solutions can be generated\nthat are guaranteed to be optimal (or within a pre-specified\noptimality gap). Furthermore, conservation problems can be\nconstructed to optimize the spatial allocation of different\nmanagement actions or zones, meaning that conservation\npractitioners can identify solutions that benefit multiple\nstakeholders. To solve large-scale or complex conservation\nplanning problems, users should install the Gurobi optimization\nsoftware (available from ) and the\n'gurobi' R package (see Gurobi Installation Guide vignette for\ndetails). Users can also install the IBM CPLEX software\n()\nand the 'cplexAPI' R package (available at\n). Additionally, the 'rcbc' R\npackage (available at )\ncan be used to generate solutions using the CBC optimization\nsoftware (). For further\ndetails, see Hanson et al.

Thanks to Ramon the creator of \\@wilmund for bug report.\n- Fix bugs in `spec_area_targets()`, `spec_duran_targets()`,\n `spec_max_targets()`, `spec_min_targets()`, `spec_pop_size_targets()`,\n and `spec_rule_targets()` functions that yielded incorrect targets or errors\n when used with `add_group_targets()` (#416).

Thanks to Ramon the creator of \\@wilmund\n for bug report.\n- Fix bug in internal `is_area_units` function that incorrectly detected\n density-based units (e.g., `\"km^-2\"` or `\"1/km^2\"`) as area-based units\n (#417). This bug meant that users could mistakenly supply invalid units\n to parameters for target specification (e.g., `area_units` parameter of\n the `spec_jung_targets()`) and subsequently obtain incorrect results. Instead,\n these functions should have instead thrown an error regarding the invalid\n units. Thanks to Ramon the creator of \\@wilmund for bug report.\n## Documentation updates\n\n- Fix minor mistakes in documentation for `loglinear_interpolation()`,\n `spec_polak_targets()`, `spec_rl_species_targets()`, `spec_sreekar_targets()`,\n `spec_ward_targets()`, and `spec_watson_targets()` functions (#417).
