v5.2.0

Highlights

• Large operator expansion — Dozens of new functions aligned with Lodash/Ramda-style workflows: list/tuple helpers (compact, chunk, partition, zip, zipAll, unzip / transpose, zipWith), set/uniqueness with custom equality (uniqueBy, differenceWith, intersectionWith, unionWith), sorting and search (sortBy, findIndex, findLastIndex, nth), flatten variants (flattenDeep, flattenDepth), list ergonomics (initial / init, tail / rest, symmetricDifference), functional combinators (flip, once, allPass / overEvery, anyPass / overSome, cond, ifElse, when, unless, juxt / over, converge, reduceRight, scan), object/path utilities (pickBy, omitBy, mapKeys, invert, invertBy, defaults, evolve), producers (range, times, clamp, repeat), roadmap-style additions (findWhere, indexOf, lastIndexOf, countBy, sortedIndex, slice, toPairs / pairs, pad, has, merge / extend, sample, shuffle / randomize, sortKeys, uniqueId, constant, noop, now, remove family, prepend / unshift, append / unpop, product, after, before, wrap, random, shift, pop, splice, invoke, matchesAny, lastly, memoize, mixin / setCustom, drop), plus uniq as an alias of unique.
• Type and introspection helpers — isArray, isBoolean, isDate, isEqual, isFinite, isFloat, isFunction, isInteger, isNaN, isNull, isNumber, isObject, isRegExp, isResource, isScalar, isString, isTraversable, typeOf.
• PHP 8.x hardening — Cleared deprecation sources across src/ and tests; PHPUnit is configured to treat deprecations as failures so CI catches regressions.
• Docs and CI — Regenerated docs/Operations.md for all new APIs; removed in-repo docs/Roadmap.md; Travis matrix targets PHP 8.2–8.4 (newer minors can still be checked locally via Docker).
