- new and improved decomposition-based heuristics,
<br>
- updates to the Benders decomposition framework,
<br>
- dual postsolving of LP solutions in PaPILO,
<br>
- substantial ecosystem improvements in GCG,
<br>
- a major revision and generalization of the UG framework,
<br>
- improved heuristics, presolving, and relaxations in SCIP-SDP,
