Fixed critical bug where multipart form fields using triple-quoted block strings with @contentType annotations would disappear after saving. Enhanced grammar to allow text after closing quotes and fixed regex to handle multiline content. Added comprehensive test coverage with 169 passing tests.

Introduces an alphabetical sorting option for folders inside collections, updates the collection UI to allow selecting folder sort mode, and persists the preference so folder ordering remains consistent across sessions. Includes accompanying UI updates and tests to validate the new behavior.

Fixes an import crash when js-yaml auto-converts date-like strings to Date objects (which caused .match() to throw). The YAML parser now uses jsyaml.CORE_SCHEMA to keep values as strings, and normalizeVariables() was hardened with defensive type checks and Invalid Date handling. Includes 13 new tests covering dates, numbers, booleans, and mixed types; all tests pass with no regressions.

Resolved critical bug preventing 'Switch File Editor' from working on Windows. Implemented three-layer fix: backend path normalization, frontend defensive checks, and comprehensive test coverage. Fixed malformed file:// URL processing that created invalid paths like \file\C:\path.

Implemented RFC 7231 compliant security feature that automatically strips sensitive headers (Authorization, Cookie) during cross-domain redirects while preserving them for same-origin redirects. Added comprehensive test coverage and security logging to timeline. Follows browser security standards.
