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).

Breaking changes

VarName constructors

Removed the constructors VarName(vn, optic) (this wasn't deprecated, but was dangerous as it would silently discard the existing optic in vn), and VarName(vn, ::Tuple) (which was deprecated).

Usage of VarName(vn, optic) can be directly replaced with VarName{getsym(vn)}(optic).

Other changes

Optic normalisation

In the inner constructor of a VarName, its optic is now normalised to ensure that the associativity of ComposedFunction is always the same, and that compositions with identity are removed.
This helps to prevent subtle bugs where VarNames with semantically equal optics are not considered equal.

StatsBase.predict in v0.10.0 calls a four argument implementation of predict, which is a mistake. This release resolves this by removing the unintended NamedTuple argument. Now it called the intended three-argument StatsBase.predict(Random.default_rng(), model, params).
