RELEASE NOTES
Version 4.8.next
================
- Planned features
- rewritten NIA (non-linear integer arithmetic) core solver
- self-contained character theory, direct support for UTF8, Unicode character sets
- recursive function representation without hoisting ite expressions. Issue #2601
- specialized solver support for QF_ABV and ABV based on lazy SMT and dual reduction
- model-based interpolation for quantifier-free UF, arithmetic, arrays
- circuit optimization techniques for BV pre-processing
Version 4.8.7
=============
- New features
- setting parameter on solver over the API by
solver.smtlib2_log=<filename>
enables tracing calls into the solver as SMTLIB2 commands.
It traces, assert, push, pop, check_sat, get_consequences.
- Notes
- various bug fixes
- rewmove model_compress. Use model.compact
- print weights with quantifiers when weight is != 1
