   Release Notes:

   StructuralEquationModels.jl v0.5.0

   This is a large, breaking release centered on a modular redesign of the model/type system to unify single models and collections/multigroup models.

   Highlights

   • a Sem is now a weighted sum of loss terms, each SEM loss bundling its own observed + implied parts.
   • New inference methods: CFI, p-values (z-test) and confidence intervals, parallel bootstrap.
   • Multigroup χ²/RMSEA/estimates now match lavaan.
   • Optimization backends (NLopt, Proximal) moved to package extensions.
   • Data simulation, FIML mean structures, and efficient re-fitting via replace_observed.

   Breaking changes

   • Type-system & evaluation overhaul.
     • Loss functions are now AbstractLoss/SemLoss; evaluate! is implemented per loss term (no model argument) (Refactor objective/gradient/hessian evaluation #214).
     • SemImply → SemImplied (Rename SemImply to SemImplied #235).
     • Multigroup/collections handled by the new Sem term structure (Refactor Sem multi-group support #317).
     • Specification and Variables APIs refactored (Refactor SEM Specification #203, Cleanup Variables API #207).
   • SemOptimizer API refactor (Refactor SemOptimizer API #299).
   • Optimization backends are now extensions — you must using NLopt / using ProximalAlgorithms to enable engine = :NLopt / :Proximal (Support optimization backends via package extensions #228, Switch to ProximalAlgorithms v0.7 #234).
   • Renames: params / param_labels (Rename params #253, Rename params (#253) #257); df → dof (rename df => dof #254).
   • Multigroup fit statistics now use the per-group Wishart/GLS convention: χ² = Σ_g (N_g−1)·F_g (new :nsamples_corrected default weighting; N−G χ² multiplier for ML/WLS; matching RMSEA). Multigroup ML/WLS results now match lavaan wishart/GLS; single-group results are unchanged except ML RMSEA. FIML is unchanged.

   New features

   • CFI fit measure (Add CFI #313).
   • Inference: z-test p-values and normal-theory confidence intervals (Convergence, bootstrap, p-values #316).
   • Bootstrap standard errors refactored, with optional parallel fitting (refactor bootstrap se and allow parallel fitting #314).
   • replace_observed for collections (Replace observed collections #266).

   Bug fixes

   • Multigroup fit-measure corrections (Cleanup fitmeasures mg #311), RMSEA correction, and the χ² multiplier/weighting fix.
