- OCaml version greater than or equal to 4.08.1 required.
- introduce check-only annotations for requires, ensures, loop invariant and lemmas
-`\from` now accepts `&v` expressions
- add option `-print-config-json`, to output Frama-C configuration data in JSON format
- new option `-explain`, which provides help messages for options used on the command line
- add option `-print-cpp-commands`, to print the preprocessing commands used by Frama-C
- support for C11's `_Noreturn` and `_Thread_local` specifiers
- allows for axiomatic blocks-like extensions
### Aorai
- Ya automata can set auxiliary variables during a transition, and use such variables in subsequent guards.
### E-ACSL
- support of bitwise operators
- support of `\separated`
- support of `complete` and `disjoint` behaviors
- support of logical array comparisons
### Eva
- easier setup of dynamic allocation builtins: new option `-eva-alloc-builtin` to configure uniformly their behavior (instead of mapping each `malloc`/`calloc`/`realloc` function to the corresponding builtin), and new annotation `eva_allocate` to locally override the global option
- new builtins for trigonometric functions `acos`, `asin` and `atan` (and their single-precision version `acosf`, `asinf`, `atanf`)
- improved automatic loop unroll (`-eva-auto-loop-unroll` option) on loops with several exit conditions, conditions using equality operators, temporary variables introduced by the Frama-C normalization or `goto` statements
### Markdown Report
- update Sarif output to 2.1.0 and prettier URI
### Variadic
- the generated code is now compilable and compatible with E-ACSL
### WP
- upgraded Why3 backend (requires why3 1.3.3)
- support of the `\initialized` ACSL predicate
- support for generalized check-only ACSL annotations
- added support for Why3 interactive prover (Coq)
- new tactic Bit-Test range
- memory model hypotheses warnings are more precise
- new experimental option: `-wp-check-memory-model` to automatically check memory model hypotheses
- new warning `pedantic-assigns`. WP needs precise `assigns ... \from ...` specification about out pointers to generate precise proof hypotheses
