title: Release of Frama-C 19.0 (Potassium)

Frama-C 19.0 (Potassium) is out. Download it here.

Main changes with respect to Frama-C 18 (Argon) include:

Kernel:

• new check annotation, similar to assert except that it does not introduce additional hypotheses on the program state
• new options added to frama-c-script

GUI:

• compatibility with lablgtk3

Eva:

• New annotation "//@ split exp" to separate the analysis states for each possible value of an expression until a "//@ merge exp" annotation.
• New option -eva-partition-history to delay the join of the analysis states at merging points; useful when a reasoning depends on the path taken to reach a control point.
• By default, prints a summary at the end of the analysis.
• New meta option -eva-precision to globally configure the analysis.
• Improved precision on nested loops.

WP:

• new auto-search mode to automatically apply strategies and tactics (see -wp-auto)
• extended simplifications on range, bitwise and C-boolean values (_Bool is now handled by default)
• refactored float model (although it still requires further axiomatisation)

E-ACSL:

• support for user-defined logic functions and predicates without labels
• new option -e-acsl-functions that allows the user to specify a white/black list of functions in which annotations are monitored, or not.
