Month: 2025-10 Concise monthly summary focusing on key accomplishments for SeleniumHQ/selenium. The month’s work concentrated on stability and correctness improvements in the Python bindings and on more robust webserver content handling. No explicit customer-facing bug fixes were reported this month; the emphasis was on reducing test flakiness, improving internal test reliability, and enhancing content serving accuracy.

September 2025 (2025-09) — SeleniumHQ/selenium: Delivered BiDi Browsing Context enhancements and expanded test coverage to strengthen cross-browser reliability and debugging visibility. Key deliverables include downloadEnd support and DownloadInfo for downloadWillBegin, navigation failure event handling, and Chrome FedCM test enablement by removing blockers. These efforts improve end-to-end test reliability, enable richer event inspection data, and accelerate release readiness for BiDi features.

August 2025 — Key delivery across SeleniumHQ/selenium focused on BiDi automation, cross-browser testing stability, and policy standardization. Implemented BiDi input actions, event handling, and user prompt improvements; added a low-level Input BiDi API and expanded test coverage for navigation/history updates. Enhanced Firefox driver service to connect to existing Firefox instances via Marionette and support a custom WebSocket port for BiDi, with tests. Enabled Chrome Beta tests in CI, and standardized SameSite cookie handling with a Default option across bindings. Addressed reliability through tests and docs fixes and standardized OS detection in Python bindings.

July 2025 monthly summary for SeleniumHQ/selenium focused on delivering BiDi-driven features and stability improvements across the Python bindings and CI tooling. Key outcomes include the introduction of high-level BiDi script management APIs (pin, unpin, execute) with robust argument handling and comprehensive test coverage; the addition of BiDi geolocation emulation with WebDriver integration and unit tests; BiDi browser context enhancements adding accept_insecure_certs and proxy parameters with extensive configuration tests; and CI/Selenium Manager stability improvements by pinning browser versions for deterministic testing, updating Selenium Manager artifacts to the latest builds, and disabling a flaky Java test to improve overall stability.

June 2025 focused on expanding BiDi capabilities in Selenium Python bindings, enhancing test coverage, and improving cross-browser stability. Key deliveries include new BiDi Permissions API, the BiDi Script Module, and HistoryUpdatedParams timestamp, along with cross-browser cookies test stabilization and documentation clarifications for ChromiumOptions. These efforts strengthen automation reliability, reduce onboarding friction, and improve the developer experience across the Selenium platform.

For May 2025, Selenium Python bindings gained significant BiDi capabilities and robustness. Delivered a BiDi storage module to manage cookies (set/get/delete) with attributes and partitioning, with integration tests; added BiDi webExtension support to install/uninstall extensions via path, archive, or base64 with tests, enabling web extensions on Chromium-based browsers. Improved error reporting and test reliability across bindings: include exception messages in execute errors, unify generator-exit handling, and expand tests for Edge storage and remote download file-type checks. Collectively these changes enhance automation reliability, cross-browser support, and developer productivity by enabling richer BiDi control and stable test suites. Technologies include BiDi protocol, Python bindings, Chromium/Edge testing, and test engineering.

April 2025 summary for SeleniumHQ/selenium: Delivered cross-language BiDi capabilities across Python, Java, and WebDriver BiDi, enabling richer browser automation and more reliable session management. Major features introduced include BiDi Python Browser and Browsing Context modules, Java BiDi onNavigationCommitted event support, and WebDriver BiDi session.status with a dedicated Session class, complemented by refactored subscription logic and comprehensive tests. These efforts provide stronger API coverage, improved navigation handling, and better test stability, driving business value by enabling more robust end-to-end automation and faster iteration cycles for clients.

In March 2025, SeleniumHQ/selenium delivered targeted improvements to the BiDi testing surface and infrastructure, plus cross-browser permission bindings and documentation/CI maintenance. These efforts increased test reliability, expanded coverage for storage and user-context scenarios, and provided programmatic permission controls across browsers, while improving internal test infrastructure and developer experience.

February 2025 monthly summary for SeleniumHQ/selenium: Delivered API improvements and a critical bug fix that enhance reliability, testability, and cross-language automation capabilities across Java and JavaScript/BiDi modules. The work focused on two high-impact changes: a bug fix for RemoteWebDriver.getDownloadableFiles with updated documentation and a new unit test, and the introduction of the getClientWindows API with new data models and comprehensive tests/build updates.
