+    - `array_concat`
+    - `array_create`
+    - `array_interpolate_linear`

+- `array_modify`: Change the default value for `length` from `1` to `0`. [#312](https://github.com/Open-EO/openeo-processes/issues/312)
+- Renamed `text_merge` to `text_concat` for better alignment with `array_concat` and existing implementations.
+- `apply_neighborhood`:
+    - Allow `null` as default value for units.
+    - Input and Output for the `process` can either be data cubes or arrays (if one-dimensional). [#387](https://github.com/Open-EO/openeo-processes/issues/387)
+- `run_udf`: Allow all data types instead of just objects in the `context` parameter. [#376](https://github.com/Open-EO/openeo-processes/issues/376)

+    - Require at least one band if not set to `null`. [#372](https://github.com/Open-EO/openeo-processes/issues/372)
+    - Added a `NoDataAvailable` exception
+- `aggregate_temporal`, `filter_temporal`, `load_collection` and `load_result`/`load_stac`:
+    - The temporal intervals must always be non-empty, i.e. the second instance in time must be after the first instance in time. [#331](https://github.com/Open-EO/openeo-processes/issues/331)
+    - `24` as the hour is not allowed anymore. [#331](https://github.com/Open-EO/openeo-processes/issues/331)

+- `save_result`: Added a more concrete `DataCubeEmpty` exception.

+    - Allows more than 3 input dimensions [#126](https://github.com/Open-EO/openeo-processes/issues/126)

+    - Clarify how the resulting vector data cube looks like  [#356](https://github.com/Open-EO/openeo-processes/issues/356)
+- Renamed `create_raster_cube` to `create_data_cube`. [#68](https://github.com/Open-EO/openeo-processes/issues/68)
+- Updated the processes based on the subtypes `raster-cube` or `vector-cube` to work with the subtype `datacube` instead. [#68](https://github.com/Open-EO/openeo-processes/issues/68)
+- `sort` and `order`: The ordering of ties is not defined anymore. [#409](https://github.com/Open-EO/openeo-processes/issues/409)
+- `quantiles`: Parameter `probabilities` provided as array must be in ascending order. [#297](https://github.com/Open-EO/openeo-processes/pull/297)
+- `fit_curve` and `predict_curve`: Heavily modified specifications. `fit_curve` works on arrays instead of data cubes, `predict_curve` doesn't support gap filling anymore, clarify no-data handling, ... [#425](https://github.com/Open-EO/openeo-processes/issues/425)
+- `climatological_normal`: The `climatology_period` parameter accepts an array of integers instead of strings. [#331](https://github.com/Open-EO/openeo-processes/issues/331)
+
+### Deprecated
+
+- `aggregate_spatial`, `filter_spatial`, `load_collection`, `mask_polygon`: GeoJSON input is deprecated in favor of `load_geojson`. [#346](https://github.com/Open-EO/openeo-processes/issues/346)
+
+### Removed
+
+- The `examples` folder has been migrated to the [openEO Community Examples](https://github.com/Open-EO/openeo-community-examples/tree/main/processes) repository.
+- `between`: Support for temporal comparison. Use `date_between` instead. [#331](https://github.com/Open-EO/openeo-processes/issues/331)
+- Deprecated `GeometryCollections` are not supported any longer. [#389](https://github.com/Open-EO/openeo-processes/issues/389)
+- Deprecated PROJ definitions for the CRS are not supported any longer.
+- `load_result`:
+    - Renamed to `load_stac`
+    - The subtype `job-id` was removed in favor of providing a URL. [#322](https://github.com/Open-EO/openeo-processes/issues/322), [#377](https://github.com/Open-EO/openeo-processes/issues/377), [#384](https://github.com/Open-EO/openeo-processes/issues/384)
+    - GeoJSON input is not supported any longer. Use `load_geojson` instead. [#346](https://github.com/Open-EO/openeo-processes/issues/346)
+- The comparison processes `eq`, `neq`, `lt`, `lte`, `gt`, `gte` and `array_contains`:
+    - Removed support for temporal comparison. Instead explicitly use `date_difference`.
+    - Removed support for the input data types array and object. [#208](https://github.com/Open-EO/openeo-processes/issues/208)
+- `sort` and `order`: Removed support for time-only values. [#331](https://github.com/Open-EO/openeo-processes/issues/331)
+
+### Fixed
+
+- `aggregate_spatial`:
+    - Clarified that feature properties are preserved for vector data cubes and all GeoJSON Features. [#270](https://github.com/Open-EO/openeo-processes/issues/270)
+    - Clarified that a `TargetDimensionExists` exception is thrown if the target dimension exists.
+- `apply` and `array_apply`: Fixed broken references to the `absolute` process
+- `apply_dimension`: Clarify the behavior for when a dimension gets 'dropped'.  [#357](https://github.com/Open-EO/openeo-processes/issues/357)
+- `apply_neighborhood`:
+    - Parameter `overlap` was optional but had no default value and no schema for the default value defined.
+    - Clarified that the overlap must be included in the returned data cube but value changes are ignored. [#386](https://github.com/Open-EO/openeo-processes/issues/386)
+    - Removed a conflicting statement that dimension labels can be changed. [#385](https://github.com/Open-EO/openeo-processes/issues/385)
+- `array_contains` and `array_find`: Clarify that giving `null` as `value` always returns `false` or `null` respectively, also fixed the incorrect examples. [#348](https://github.com/Open-EO/openeo-processes/issues/348)
+- `array_interpolate_linear`: Return value was incorrectly specified as `number` or `null`. It must return an array instead. [#333](https://github.com/Open-EO/openeo-processes/issues/333)
+- `is_nan`: Fixed a wrong description of the return value and simplified/clarified the process descriptions overall. [#360](https://github.com/Open-EO/openeo-processes/issues/360)
+- `is_nodata`: Clarified that `NaN` can be considered as a no-data value only if it is explicitly specified as no-data value. [#361](https://github.com/Open-EO/openeo-processes/issues/361)
+- `merge_cubes`: Clarified descriptions to better describe when a merge is possible. [#379](https://github.com/Open-EO/openeo-processes/issues/379)
+- `rename_labels`: Clarified that the `LabelsNotEnumerated` exception is thrown if `source` is empty instead of if `target` is empty. [#321](https://github.com/Open-EO/openeo-processes/issues/321)
+- `round`: Clarify that the rounding for ties applies not only for integers. [#326](https://github.com/Open-EO/openeo-processes/issues/326)
+- `save_result`: Clarified that the process always returns `true` (and otherwise throws). [#334](https://github.com/Open-EO/openeo-processes/issues/334)
+- Handling of empty geometries is clarified throughout the processes. [#404](https://github.com/Open-EO/openeo-processes/issues/404)

 * The `*.json` files in the [`proposals`](proposals/) folder provide proposed new process specifications that are still experimental and subject to change, including breaking changes. Everyone is encouraged to base their work on the proposals and give feedback so that eventually the processes evolve into stable process specifications.
 * [implementation.md](meta/implementation.md) in the `meta` folder provide some additional implementation details for back-ends. For back-end implementors, it's highly recommended to read them.
 * [subtype-schemas.json](meta/subtype-schemas.json) in the `meta` folder defines common data types (`subtype`s) for JSON Schema used in openEO processes.
-* The [`examples`](examples/) folder contains some useful examples that the processes link to. All of these are non-binding additions.
+* Previously, an `examples` folder contained examples of user-defined processes. These have been migrated to the [openEO Community Examples](https://github.com/Open-EO/openeo-community-examples/tree/main/processes) repository.
 * The [`tests`](tests/) folder can be used to test the process specification for validity and consistent "style". It also allows rendering the processes in a web browser. Check the [tests documentation](tests/README.md) for details.
