Release notes

ConvolvedDistributions.jl follows a hybrid changelog approach:

• GitHub Releases: All releases (automatically generated by TagBot)

• NEWS.md: Major releases requiring detailed context (shown below)

See GitHub Releases for minor/patch release information.

Unreleased

• Pre-release parity pass against the CensoredDistributions.jl integration branch: ported the ambiguity-free ForwardDiff _gamma_cdf Dual overloads and the AD-safe Gamma logcdf/logccdf Dual routing, enabled the extension-ambiguity QA checks, clamped discretised delay-PMF masses at zero, added a compact GaussLegendre show, removed the never-released force_numeric shim, and made _ccdf_ad_safe/_logccdf_ad_safe public (ComposedDistributions.jl extends them).

• Added the AbstractCombinedDistribution family supertype (mirroring the CensoredDistributions.jl abstract hierarchy) that Convolved and Difference now subtype, with the interface contract documented on the type and shipped TestUtils.test_combined_interface / TestUtils.test_abstract_membership verifiers for downstream family members.

• Added the timeseries form convolve_series(delay, series): a numeric series (e.g. expected infections at unit-spaced times) convolved with the discretised delay PMF of any univariate distribution, ported censoring-free from CensoredDistributions.jl with AD-safe CDF-difference interval masses (#6).

• Restored quantile (inverse CDF) for Convolved and Difference via the new ConvolvedDistributionsOptimizationExt extension, loaded when both Optimization.jl and OptimizationOptimJL.jl are present (#20).
