| 11 | + Today we're happy to announce that Selenium 4.47 has been released! |

| 14 | +We’re excited to announce the release of **Selenium 4.47** for JavaScript, Ruby, Python, .NET, Java |
| 15 | +and the Grid! 🎉 |

| 22 | +# Selenium 4.47 Released |
| 23 | + |
| 24 | +## ✨ Highlights |
| 25 | + |
| 26 | +- **BiDi** Continued unifying the BiDi protocol layer across bindings around the shared, |
| 27 | + binding-neutral CDDL-derived schema — Ruby now generates its BiDi domain type accessors, union |
| 28 | + variant factories, and typed errors from it, matching JavaScript's earlier adoption. |
| 29 | +- **[Java]** Removed the redundant BiDi subscription scope tracking and fixed BiDi not |
| 30 | + initializing for `RemoteWebDriver` built via the builder. |
| 31 | +- **[.NET]** BiDi transport factories are now composable, the optional command timeout was |
| 32 | + removed from command options, and spurious warnings when there are no BiDi subscribers are |
| 33 | + gone. |
| 34 | +- **[.NET][Python][Ruby]** Firefox now blocks CDP access, reinforcing BiDi as the standard |
| 35 | + cross-browser protocol. |
| 36 | +- **[Grid]** Dynamic Grid videos are now consistently stored in a per-session subfolder via |
| 37 | + `SE_VIDEO_SESSION_SUBFOLDER`, including on Kubernetes, removing the previous pod-wait and |
| 38 | + relocation logic. |
| 39 | +- **[Java]** Fixed `By.className()`/`By.id()` misescaping non-ASCII leading digits, and a |
| 40 | + `By.name()` double `String.format` bug on names containing `%`. |
| 41 | +- **[Rust]** Selenium Manager fixes: honors `--browser-version` for Electron driver resolution, |
| 42 | + locates Chrome and Edge in known install directories, and no longer caches an empty driver |
| 43 | + version. |
| 44 | + |

| 46 | + |
| 47 | +## 📦 Notable Changes |
| 48 | + |
| 49 | +### Java |
| 50 | +- Removed the redundant BiDi subscription scope tracking, and fixed BiDi not initializing for |
| 51 | + `RemoteWebDriver` built via the builder. |
| 52 | +- Fixed `By.className()`/`By.id()` misescaping non-ASCII leading digits, and a `By.name()` double |
| 53 | + `String.format` bug on names containing `%`. |
| 54 | +- Added regression coverage for relative locators on collapsed table borders. |
| 55 | +- Removed deprecated FTP proxy support and deprecated invalid Firefox profile code (shared with |
| 56 | + JavaScript, Ruby, and .NET). |
| 57 | + |
| 58 | +### Python |
| 59 | +- Blocked CDP access with Firefox (shared with .NET and Ruby). |
| 60 | +- Fixed `no_proxy` matching so empty entries and substrings no longer bypass the proxy. |
| 61 | +- `find_element`/`find_elements` type hints now accept `By`. |
| 62 | +- Ensured driver service subprocess resources are cleaned up. |
| 63 | +- Fixed the default `command_executor` URL in the `RemoteWebDriver` docstring. |
| 64 | + |
| 65 | +### Ruby |
| 66 | +- Generated the BiDi domain type accessors, union variant factories, and typed WebDriver errors |
| 67 | + from the shared binding-neutral schema. |
| 68 | +- Constructed the BiDi transport inside the domain from a connection, and routed BiDiBridge |
| 69 | + navigation through the generated `Protocol::BrowsingContext`. |
| 70 | +- Added inbound/outbound validation for BiDi fields, including nullable-constant params, ref |
| 71 | + fields, and float/enum type fidelity. |
| 72 | +- Added support for WebDriver BiDi on Safari Preview, moving `#bidi` onto `Driver`. |
| 73 | +- Added a `browser_family` test guard, and support for custom vendor-specific capabilities in |
| 74 | + options classes. |
| 75 | + |
| 76 | +### .NET |
| 77 | +- Made BiDi transport factories composable. |
| 78 | +- Removed the optional command timeout from command options, and stopped warning when there are |
| 79 | + no BiDi subscribers. |
| 80 | +- Added support for `SE_*DRIVER` environment variables to set driver locations. |
| 81 | +- Blocked CDP access with Firefox (shared with Python and Ruby). |
| 82 | + |
| 83 | +### Grid |
| 84 | +- Store Dynamic Grid videos in a per-session subfolder via `SE_VIDEO_SESSION_SUBFOLDER`, |
| 85 | + including on Kubernetes, removing the previous pod-wait and relocation logic. |
| 86 | +- Inherited the Node Pod container's `securityContext` for Dynamic Grid on Kubernetes. |
| 87 | +- Honored client-advertised `se:remoteUrl` for reachable BiDi/CDP/VNC URLs. |
| 88 | + |
| 89 | +### Build & Infra |
| 90 | +- Continued the BiDi schema unification: merged vendor CDDL files into the shared schema, derived |
| 91 | + per-type inbound/outbound directionality, and cleaned up schema generation. |
| 92 | +- Published a Selenium 5 release charter and an ADR documenting BiDi implementation boundaries. |
| 93 | +- Generated a cross-platform Selenium Manager SBOM and NOTICE, bundled into each package. |
| 94 | +- Bumped Rust build tooling (`@llvm`, `rules_rs`, `rules_ruby`) and updated Node.js versioning for |
| 95 | + testing and publishing. |
| 96 | + |
| 97 | +--- |
| 98 | + |
| 99 | +### 🐳 Docker Selenium |
| 100 | + |
| 101 | +- Docker: Support Google Chrome images for linux/arm64 (#3187) |
| 102 | +- [build] Keep Chrome dev/beta images on linux/amd64 only, resolve the latest rclone tag (#3188) |
| 103 | +- [video] Fall back to SE_NODE_CONTAINER_NAME for the per-session subfolder (#3194) |
| 104 | +- K8s: Implement KEDA external scaler and use it as default (#3169) |
| 105 | +- K8s: Gate distributed component replicas on external datastore (#3175) |
