v0.13.0

AbstractPPL v0.13.0

Diff since v0.12.0

There are no breaking changes; however, we opted to make a minor release given the substantial amount of new code.

Minimum compatibility has been bumped to Julia 1.10.

Added the new functions hasvalue(container::T, ::VarName[, ::Distribution]) and getvalue(container::T, ::VarName[, ::Distribution]), where T is either NamedTuple or AbstractDict{<:VarName}.

These functions check whether a given VarName has a value in the given NamedTuple or AbstractDict, and return the value if it exists.

The optional Distribution argument allows one to reconstruct a full value from its component indices.
For example, if container has x[1] and x[2], then hasvalue(container, @varname(x), dist) will return true if size(dist) == (2,) (for example, MvNormal(zeros(2), I)).
In this case plain hasvalue(container, @varname(x)) would return false, since we can not know whether the vector-valued variable x has all of its elements specified in container (there might be an x[3] missing).

These functions (without the Distribution argument) were previously in DynamicPPL.jl (albeit unexported).
