| connection conditional on the `AttachA11yView` flag. |
| * Changes: [fxr/1207064](https://fuchsia-review.googlesource.com/c/fuchsia/+/1207064) |
| |
| ## Audio |
| |
| The following updates have been made for Audio: |
| |
| * **Improved the Audio Device Registry (ADR)** to gracefully handle Composite |
| device removals, preventing potential crashes. A new platform configuration |
| flag has also been introduced to control the eager startup of the ADR |
| service. |

| * **Enhanced audio drivers** for improved stability and identification. |
| AML-G12 drivers now expose `manufacturer` and `product` properties, use the |
| SDK `platform-device` library, and no longer crash if `Stop` is called |
| before `Start`. The `intel-hda` driver now correctly handles the creation of |
| a second ring buffer. |

| The following updates have been made for GPU and Graphics: |
| |
| * **Significantly improved Magma's core.** Semaphores now use `zx::counter` |
| instead of `zx::vmo` for better performance and lower memory use. |
| Additionally, context creation now supports priorities, buffer release is |
| safer on connection shutdown, and a new C++ to C binding library is |
| available. |
| * Changes: |
| [fxr/1262224](https://fuchsia-review.googlesource.com/c/fuchsia/+/1262224), |

| |
| ## IOT, Matter, and Thread |
| |
| The following updates have been made for IOT, Matter, and Thread: |
| |
| * **Updated the `third_party/openthread` dependency**. This update includes |
| new features and fixes such as improved border agent and routing manager |
| functionality, support for ePSKc, and alignment of LoWPAN components with |
| the latest OpenThread version. Fuchsia's platform code, tests, and bindings |
| were also updated for compatibility. |
| * Changes: |
| [fxr/1233151](https://fuchsia-review.googlesource.com/c/fuchsia/+/1233151), |
| [fxr/1258025](https://fuchsia-review.googlesource.com/c/fuchsia/+/1258025), |

| directly within the OpenThread netstack. |
| * Changes: [fxr/1259525](https://fuchsia-review.googlesource.com/c/fuchsia/+/1259525) |
| |
| ## Kernel |
| |
| The following updates have been made for Kernel: |
| |
| * **Implemented the `ZX_VM_FAULT_BEYOND_STREAM_SIZE` flag** for `zx_vmar_map`. |
| This allows memory access beyond a VMO's content size to fault, improving |
| compatibility with POSIX `mmap` semantics. |
| * **Added support for ktrace streaming.** `zx_ktrace_read` now consumes the |
| data it reads, enabling userspace to stream kernel trace data by invoking |
| this syscall in a loop. As part of this cleanup, the unused |
| `zx_ktrace_write` syscall was removed. |
| |
| * **Added support for mappable kernel clocks.** These clocks support efficient |
| read access without entering the kernel in most circumstances. See [RFC |
| 0266](/docs/contribute/governance/rfcs/0266_memory_mappable_kernel_clocks.md) |
| for details on the design. |
| |
| ## Netstack |

| rolls out to 100% and before F28 starts rolling out.** |
| * **Introduced comprehensive support for TCP Selective Acknowledgement |
| (SACK)**, including SACK-based loss recovery and congestion control updates, |
| to significantly improve TCP performance over lossy networks. |
| * Changes: [fxr/1242089](https://fuchsia-review.googlesource.com/c/fuchsia/+/1242089) |
| * Bugs: [fxb/42078221](https://fxbug.dev/42078221) |

| ### ffx |
| |
| The following updates have been made for ffx: |
| |
| * **Removed the daemon-based package server from `ffx`.** All associated |
| commands (`ffx repository add`, `list`, `remove`, `status`, etc.) are also |
| removed. Users should now use the standalone `ffx repository server` |
| commands. |
| * Changes: |
| [fxr/1223504](https://fuchsia-review.googlesource.com/c/fuchsia/+/1223504), |
| [fxr/1225307](https://fuchsia-review.googlesource.com/c/fuchsia/+/1225307), |

| [fxr/1229749](https://fuchsia-review.googlesource.com/c/fuchsia/+/1229749) |
| * Bugs: [fxb/393632288](https://fxbug.dev/393632288), |
| [fxb/393632047](https://fxbug.dev/393632047) |
| * **Improved networking and connectivity.** `ffx` now correctly handles IPv6 |
| addresses with scope IDs, provides more useful error messages for connection |
| failures, and more robustly discovers and manages targets, especially over |
| USB/VSOCK. Support for Overnet over VSOCK has also been added. |
| * Changes: |
| [fxr/1260729](https://fuchsia-review.googlesource.com/c/fuchsia/+/1260729), |
| [fxr/1254328](https://fuchsia-review.googlesource.com/c/fuchsia/+/1254328), |
| [fxr/1249646](https://fuchsia-review.googlesource.com/c/fuchsia/+/1249646), |
| [fxr/1253433](https://fuchsia-review.googlesource.com/c/fuchsia/+/1253433), |

| [fxr/1222685](https://fuchsia-review.googlesource.com/c/fuchsia/+/1222685), |
| [fxr/1245565](https://fuchsia-review.googlesource.com/c/fuchsia/+/1245565) |
| * **Added an opt-in Terminal User Interface (TUI)** for `ffx` and `fx` |
| commands to provide enhanced formatting. This can be enabled via the |
| `ffx.ui.mode` configuration. The `fx use` command is the first to adopt |
| this. |
| * Changes: [fxr/1255350](https://fuchsia-review.googlesource.com/c/fuchsia/+/1255350) |
| * **Updated `ffx product` and `ffx package` to be standalone executables,** |
| which are no longer bundled into the main `ffx` binary. This change improves |
| build times. |
| * Changes: |
| [fxr/1219912](https://fuchsia-review.googlesource.com/c/fuchsia/+/1219912), |
| [fxr/1225904](https://fuchsia-review.googlesource.com/c/fuchsia/+/1225904) |
| * **Updated the `ffx test run` command to be more automation-friendly,** |
| supporting strict output requirements and machine-readable JSON. |
| * Changes: |
| [fxr/1228427](https://fuchsia-review.googlesource.com/c/fuchsia/+/1228427), |
| [fxr/1225870](https://fuchsia-review.googlesource.com/c/fuchsia/+/1225870), |
| [fxr/1224364](https://fuchsia-review.googlesource.com/c/fuchsia/+/1224364) |
| * **Replaced the `ffx inspect` command's `--component` flag with `--data`** |
| for more intuitive querying. |
| * Changes: [fxr/1148106](https://fuchsia-review.googlesource.com/c/fuchsia/+/1148106) |
| * **Improved the `ffx driver` command** with a new `--unbound` flag to list |
| only unbound nodes and more accurate reporting of unbindable nodes. |
| * Changes: |
| [fxr/1236072](https://fuchsia-review.googlesource.com/c/fuchsia/+/1236072), |
| [fxr/1236071](https://fuchsia-review.googlesource.com/c/fuchsia/+/1236071) |
| * **Improved flashing speed and reliability.** The `ffx flash` command is now |
| significantly faster for large images due to an increased transfer buffer |
| size. It can also now correctly handle large sparse images by automatically |
| re-chunking them. A bug causing an "Unknown Ninja path" error in `fx flash` |
| has also been fixed. |
| * Changes: |
| [fxr/1252985](https://fuchsia-review.googlesource.com/c/fuchsia/+/1252985), |
| [fxr/1243987](https://fuchsia-review.googlesource.com/c/fuchsia/+/1243987), |
| [fxr/1238368](https://fuchsia-review.googlesource.com/c/fuchsia/+/1238368) |
| * **Updated the `ffx trace` command to better visualize FIDL IPC traces.** It |
| uses a two-pass approach to correctly render asynchronous two-way FIDL calls |
| as single, continuous flows in Perfetto and sets event names to FIDL method |
| names for easier debugging. |
| * Changes: |
| [fxr/1232114](https://fuchsia-review.googlesource.com/c/fuchsia/+/1232114), |

| |
| ### zxdb |
| |
| The following updates have been made for zxdb: |
| |
| * **Enabled host-side unwinding as the default in zxdb,** leveraging full |
| debugging information to provide higher-quality backtraces. A |
| `--force-remote-unwind` option has been added to revert to the previous |
| target-side behavior. |
| * Changes: |
| [fxr/1172993](https://fuchsia-review.googlesource.com/c/fuchsia/+/1172993), |

| * Bugs: [fxb/292107156](https://fxbug.dev/292107156) |
| |
| ## UI |
| |
| The following updates have been made for UI: |
| |
| * **Enabled direct-to-display** in Flatland. This allows for more efficient |
| rendering by directly displaying client images instead of composing them and |
| includes critical fixes to the buffer collection import process. |
| * Changes: |
| [fxr/1234464](https://fuchsia-review.googlesource.com/c/fuchsia/+/1234464), |

| [fxb/399228128](https://fxbug.dev/399228128) |
| * **Improved the input system and core UI stability.** These changes fix an |
| issue in Scenic's vsync interval computation to prevent crashes and add |
| support for mouse devices. |
| * Changes: |
| [fxr/1249219](https://fuchsia-review.googlesource.com/c/fuchsia/+/1249219), |
| [fxr/1236342](https://fuchsia-review.googlesource.com/c/fuchsia/+/1236342) |
| * **Enhanced performance and configurability for UI services.** Scenic and |
| Scene Manager can now be configured with thread and memory profiles, |
| allowing integrators to fine-tune resource allocation. Additionally, |
| Scenic's frame prediction margin is now parameterizable. |
| * Changes: |
| [fxr/1241924](https://fuchsia-review.googlesource.com/c/fuchsia/+/1241924), |

| the device's MAC address. |
| * Changes: |
| [fxr/1259485](https://fuchsia-review.googlesource.com/c/fuchsia/+/1259485) |
| * **The `wlantool` command-line utility can now connect to a network using a |
| BSSID** in addition to an SSID. |
| * Changes: [fxr/1226545](https://fuchsia-review.googlesource.com/c/fuchsia/+/1226545) |
| * **Refined the roaming algorithm to be more responsive and efficient.** This |
| includes making the scan backoff exponential, resetting the backoff more |
| intelligently, and simplifying the stationary roam profile by removing SNR |
| as a trigger. |
| * Changes: |
| [fxr/1252322](https://fuchsia-review.googlesource.com/c/fuchsia/+/1252322), |
