+
+Linebender is an informal open-source organization working on various projects to advance the state of the art in GUI for [the Rust programming language](https://rust-lang.org).
+
+## Xilem
+
+Xilem is our flagship GUI project, inspired by SwiftUI.
+
+- HTTP cats example ([xilem#571][]).
+- `lens`, a shorthand for a common component pattern ([xilem#587][]).
+- We added Views for some existing and new widgets:
+  - Grid layout ([xilem#570][]).
+  - Images ([xilem#571][]).
+
+<!-- TODO: Xilem Web seems to not have any especially relevant updates? -->
+
+<figure>
+
+<!-- <img style="height: auto" src="TODO" alt="TODO" height="388" width = "559"> -->
+
+<figcaption>
+
+<!-- Caption -->
+
+</figcaption>
+</figure>
+
+## Masonry
+
+Masonry is the widget system used by Xilem.
+Our ongoing pass specification project has been largely implemented.
+That work is now in a wrapping-up stage, which has allowed Olivier to work on improving the codebase's quality in general.
+Some highlights of work from September:
+
+- [xilem#515][]: Removes unimplemented functionality from our text handling code.
+- [xilem#570][]: An implementation of a grid layout, by Jared O'Connell.
+- [xilem#550][]: Restores scroll requests, as used by text inputs.
+- [xilem#565][]: Allows widgets to implement more efficient pointer position dispatching, by new Linebender member Tom Churchman.
+
+<!-- Grid example? -->
+
+Some ongoing work includes:
+
+- Text input and prose accessibility in [xilem#615][].
+- Custom client side decorations for Wayland by Marco Melorio in [xilem#606][].
+- [xilem#605][] by failingprovince which enables greater flexibility in the layout of the `Image` widget.
+- An svg like widget for absolute positioning, by Muhammad Ragib Hasin ([xilem#591][]).
+
+<!-- TODO: Figure for another video, of the talkback with keyboard actions? -->
+
+## Vello
+
+Vello is our GPU vector renderer.
+Progress towards the upcoming 0.3.0 release can be tracked in [the milestone](https://github.com/linebender/vello/milestone/2).
+
+- We now no longer consider Vello to be experimental ([vello#691][]). Please note that Vello is still an alpha, and has several known issues.
+- An implementation of the single pass scan described last month is being created by Thomas Smith in [vello#685][].
+
+## Parley
+
+Parley is a text layout library.
+
+- Nico Burns contributed a new way to assign layout properties in [xilem#76][].
+
+## Others
+
+- Daniel and Olivier's "office hours" appointments can still be booked by anyone for open-ended discussion of the ecosystem.
