-## Development and debugging
-
-Install the root and client dependencies before the first debug session:
-
-```powershell
-npm install
-npm install --prefix client
-```
-
-Use one of the checked-in VS Code launch configurations:
-
-- **Run Extension** debugs the TypeScript extension host.
-- **Debug Extension and Python** debugs both the TypeScript extension and the
-  Python language server. This is the recommended configuration for LSP work.
-- **Python Attach** attaches manually to an already running Python process.
-
-The launch configuration creates a fresh non-minified bundle with embedded
-source maps and opens `test/test.tcl` so the extension activates immediately.
-For combined debugging, the Python adapter listens on `127.0.0.1:5678`; the
-language server waits for that adapter before initialization. The NX
-Postprocessor Support output channel reports `Python debug mode: enabled` and
-shows `_debug_server.py` in the server command when the debug path is active.

 ## Release Information
 
-### Backwards-incompatible Changes
-
-- Field aliases are now resolved *before* calling `field_transformer`, so transformers receive fully populated `Attribute` objects with usable `alias` values instead of `None`.
-  The new `Attribute.alias_is_default` flag indicates whether the alias was auto-generated (`True`) or explicitly set by the user (`False`).
-  [#1509](https://github.com/python-attrs/attrs/issues/1509)
-
-
 ### Changes
 
-- Fix type annotations for `attrs.validators.optional()`, so it no longer rejects tuples with more than one validator.
-  [#1496](https://github.com/python-attrs/attrs/issues/1496)
-- The `attrs.validators.disabled()` contextmanager can now be nested.
-  [#1513](https://github.com/python-attrs/attrs/issues/1513)
-- Frozen classes can set `on_setattr=attrs.setters.NO_OP` in addition to `None`.
-  [#1515](https://github.com/python-attrs/attrs/issues/1515)
-- It's now possible to pass *attrs* **instances** in addition to *attrs* **classes** to `attrs.fields()`.
-  [#1529](https://github.com/python-attrs/attrs/issues/1529)
+- Restore support for generator-based `field_transformer`s.
