2.1.0

• A new minor release to support Hierarchy Builder 1.8.
• Added automation for reasoning about uniqueness of sequences.
• Added a type class of conical PCMs.
• Made dom infer the union_map structure, in order to support structure-specific notation for dom.
• Added a type class of total map-like functions in unionmap.v. Previous version had only partial map-like function (omap_fun), but total ones admit better lemmas.
• Generalized several \big lemmas in unionmap.v that were previously unnecessarily restricted (bigD1FE, bigPtUnE, bigPtUn, bigDUE).
• Added a number of smaller lemmas in pred, prelude, seqext, unionmap.

2.0.0

• A new major release based on mathcomp2.
• Dropped coq8.15-8.17, support 8.19-8.20.
• Complete revision of pcm, morphism, unionmap, and natmap hierarchies, based on Hierarchy Builder.
• Expanded prelude, pred, seqext, slice, uconsec and useqord infrastructure.
• Removed lift.

1.8.0

• allow Coq 8.17, drop 8.14
• allow Mathcomp 1.16, drop 1.13-14

• rename AllPn->allPnIn, HasPn->hasPnIn
• add trans_eq, if_triv, theory for foldl/r and onth in prelude, rename prefixP -> prefixE

• refactored automated lemma infrastructure
• extracted sequence intervals into a separate sub-theory
• added several natmap theories required by current FCSL examples (will be deprecated and removed in future releases): continuous & complete maps, leq surgery, exec & growth
