v9.2.1

Fixed bugs

• apply same feasibility definition in PaPILO as in SCIP to avoid numerical inconsistencies
• check variable cancellation in SCIPvarAddVlb() and SCIPvarAddVub() to avert wrong infeasibility
• SCIPfreeReoptSolve() now also clears partial solutions
• fixed bug in calculation of "fractionality score" for spatial branching candidates in cons_nonlinear
• fixed bug with installing symmetry dialog in sub-SCIPs
• added copy callbacks for presolvers dualagg and redvub, branching rules lookahead and cloud, primal heuristics dualval and repair, propagator nlobbt, and separators gauge and convexproj
• respect maximal separation rounds setting by running remaining delayed separators in last round
• replace terms consistently in applyFixings() of cons_linear to handle infinite aggregations

Build system

Cmake

• fix SCIP Optimization Suite build with -DSYM=(s)bliss and bliss being downloaded and built during configuration by cmake
• fix use of a bliss cmake installation specified via BLISS_DIR if -DSYM=(s)bliss

Makefile

• the check/solchecker build can now use also GMP installations by Homebrew on macOS/arm64

Miscellaneous

• the output precision for writing CIP/OPB files has been increased at several places for nonlinear constraints
• the solchecker tool now also supports SCIP solutions without unknown or infinite values
• generate an error if the same linear constraint is used by several indicator constraints
