Changed libraries by category/area
==================================

Collections / data structures
-----------------------------

- "dictionaries": splay-tree implementation; new "lookup/4" returning splayed tree.
- "sets": treap implementation.
- "heaps": pairing heap implementation; fixed "valid/1" for binary heaps.
- "listp"/"list"/"difflist": added "take/4".

Randomness / IDs / stats / math
-------------------------------

- "random": added SplitMix64, Xoshiro*, WELL512a support.
- "uuid": added UUIDv7 support, "uuid_nil/1", "uuid_max/1" (RFC 9562).
- "statistics": added percentile/quartiles/correlation/moments/error metrics and more.
- "natural": added "factorial/2", "binomial/3".
- "numberlist": added "linear_regression/4".
- "dates": added substantial date/time conversion and duration predicates.
- "arbitrary" + "types": added "text" and "text(CharSet)"; backend compatibility/portability fixes.

Data formats / parsing
----------------------

- "csv" and "tsv": optional comment support.
- "json" and "json_lines": fixed unused dependencies.

Functional/error-handling abstractions
--------------------------------------

- "expecteds": many new conversion/mapping/composition predicates.
- "optionals": many new conversion/mapping/composition predicates.
- "expecteds" + "optionals": added QuickCheck shrinking support.
- "validations": introduced as complementary accumulated-error model to "expecteds" fast-fail style.

Networking / integration
------------------------

- "redis": added common operation wrappers; updated to use new "sockets" compatibility library.

Portability cleanups
--------------------

- Reduced portability warnings in arbitrary, os, random, types and tools loading paths on specific backends.

Non-library notable changes
===========================

- Compiler/runtime: stricter create_object/4 and create_category/4 parameter checks; multiple fixes for include/1, initialization/1, and predicate_property/2 runtime-bound cases.
- Tools: new help::man/1; tester/doclet scripts now print runtime and improved formatting/accuracy.
- IDE support: VSCode test results now include per-entity and per-predicate coverage data.
