* Fix prototype pollution in _.set and related functions Prevents setting dangerous properties (__proto__, constructor, prototype) that could lead to prototype pollution vulnerabilities. * Fix command injection vulnerability in _.template - Add validation for the variable option to prevent injection attacks - Improve sourceURL whitespace normalization to prevent code injection * Fix cyclic value comparison in _.isEqual Properly checks both directions when comparing cyclic values to ensure correct equality comparisons for circular references. * Improve _.sortBy and _.orderBy performance and array handling - Add early return for empty arrays in sorted index operations - Improve array iteratee handling to support nested property paths - Add missing keysIn import in baseClone * Refactor _.trim, _.trimEnd, and _.trimStart implementations Extract shared trim logic into reusable utilities (_baseTrim, _trimmedEndIndex) for better code organization and consistency. Update related functions (toNumber, parseInt) to use new utilities. Improve comment accuracy. * Add documentation for predicate composition with _.overEvery and _.overSome Enhance documentation to show how _.matches and _.matchesProperty can be combined using _.overEvery and _.overSome for more powerful filtering. Add examples demonstrating shorthand predicate syntax. * Bump to v4.17.21 * Fix prototype pollution in _.unset and _.omit Prevent prototype pollution on baseUnset function by: - Blocking "__proto__" if not an own property - Blocking "constructor.prototype" chains (except when starting at primitive root) - Skipping non-string keys See: https://github.com/lodash/lodash/security/advisories/GHSA-xxjr-mmjv-4gpg * Update JSDoc documentation to align with main branch - Fix sortBy example ages (40 -> 30) for correct sort order demonstration - Fix _setCacheHas return type (number -> boolean)
