Mar 1, 2026March 2026 (2026-03) — Delivered architecture-aware iOS simulator launches and synchronized release versioning for Detox. Key changes include: support for specifying simulator launch architecture (x86_64 or arm64), architecture validation, and launch command updates; compatibility workaround to ignore --arch on iOS simulators below 26 to avoid errors; and a coordinated cross-package version bump to 20.48.x (20.48.0 -> 20.48.1) across detox-cli and related packages. These changes were implemented through targeted commits (b51d2b855582da64b8a77e4f82f3deffd951d049, 9d0d320220bb7feb92308e2c22e774cb6ac2e719, 15fc81eff4309a72a09e4283e08e83d4c3067d6e, 84dc1de5bce4e307931e23ebc4c9fd4d37dd632e).

May 1, 2025May 2025 (wix/Detox) delivered two strategic features aimed at reducing debugging time and increasing test reliability, supporting faster release cycles and higher QA confidence. Implemented Detox Interactive REPL Debugging to pause test execution for live inspection and automatically enter REPL on failures, enabling faster root-cause analysis. Introduced configurable test retry arguments (noRetryArgs) to prevent the re-application of retry-relevant arguments during retries, improving retry reliability and test stability. Updated types, tests, command runner logic, and documentation to support these features. These changes reduce mean time to diagnose issues and decrease flaky-test incidents in CI, delivering tangible business value.

Apr 1, 2025Apr 2025: Delivered a critical Monorepo Debugger Attachment Fix for Detox. The --inspect-brk CLI could not reliably attach to the correct Jest instance in multi-package setups; implemented dynamic binary path resolution using resolve-from and path.relative to attach to the appropriate Jest process. The change aligns with issue #4761 and commits aaf626433047b0c8ce477deefa38d8378ec7407a. Impact: more reliable debugging across monorepos, reduced setup time for developers, and fewer support escalations related to debugger attachment.
