@ -22,6 +22,14 @@ New in spot 2.10.3.dev (not yet released)
property of Spot to the controllable-AP header for the Extended
HOA format used in SyntComp. https://arxiv.org/abs/1912.05793
- "aliases" is a new named property that is filled by the HOA parser
using the list of aliases declared in the HOA file, and then used
by the HOA printer on a best-effort basis. Aliases can be used to
make HOA files more compact or more readable. But another
possible application is to use aliases to name letters of a 2^AP
alphabet, in applications where using atomic propositions is
inconvenient.
New in spot 2.10.3 (2022-01-15)
