# Changelog veriT follows Calendar Versioning. Version numbers are of the form YYYY.0M.MICRO i.e. year, zero-padded month, and patch level. Compatibility is only assured between versions with the same year and month. The performance on individual benchmarks might even fluctuate between patch levels. ## [2020.10] - 2020-10-14 This release is motivated by the inclusion of veriT as a backend for proof reconstruction in Isabelle. It is the first release since 2016. Since the last stable release of veriT, the solver has seen many changes. The changes mainly affect quantifier instantiation and proof production.
