Release log tracker

Here we collect the new features, bug fixes, etc. for the next release.

Announcements

This release dropped compatibility with pre-v1.0 versions of Julia (#431).

Features

• added (rudimentary) support to check properties for hybrid systems (#480, #500)
• added a new option to discretize using concrete operations on zonotopes (#528)

Bug fixes

• fixed behavior of LazyDiscretePost's option :lazy_R⋂G and added option :lazy_A⌜R⋂G⌟ for the old behavior (#459)
• fixed bloating for systems without inputs in the approximation model that uses interpolation (former assume_homogeneous option) (#503)

Enhancements

• allow to disable the max_jumps option and disable it by default (#456)
• allow using a U::LazySet for the input set of systems; it is equivalent to ConstantInput(U) (#526)

Other

• refactoring work (#430, #432)
• new page in the documentation about works citing JuliaReach related packages (#428), and another one with publications of repeatability evaluations or algorithms (#426)
• We now use the AbstractMap interface from MathematicalSystems for transitions (guards/assignmens) of hybrid automaton models (#439, #458)
• The options interface has changed. In particular, options specific to the continuous-post algorithm now need to be passed to the respective post operator, and the default values for some options has changed. (#464)
• The Properties module has become a standalone module. We renamed the property types and a method (check_property → check). Conjunction/Disjunction types have been added. LinearConstraintProperty has been removed as it can be imitated by a combination of the other property types. (#493, #494, #497)
• The options for the BFFPSV algorithm have changed. For overapproximation during decomposition and iteration, we now use a unified option :block_options. This synchronizes the code with recent corresponding changes in LazySets. (#505)
• Overhaul discretize.jl (#503)
• inout_map now uses the concrete projection of half-spaces and hpolyhedron from LazySets for property checking (#525)

Breaking changes

• ContinuousSystem and DiscreteSystem constructors are removed; use constructors from MathematicalSystems types instead (#503)
