• various bugfixes

0.6

Feature

• An already instantiated sat solver in the Sat module

• Forgetful propagations: propagations whose reason (i.e clause) is not watched

0.5.1

Bug

• Removed some needless allocations

Breaking

• Better interface for mcsat propagations

Feature

• Allow level 0 semantic propagations

0.5

0.4.1

Bug

• fix bug in add_clause

0.4

• Proofs for atoms at level 0
• Compatibility with ocaml >= 4.00
• Released some restrictions on dummy sat theories

0.2
