-:::{dropdown} DEA Coastlines 2021 dataset incorporates Landsat 9 data and uses a new tidal model. How might this affect my pre-2020 modelling?
-The addition of Landsat 9 satellite data to the underlying source data of DEA Coastlines will affect all annual shorelines from 2021 onwards. The additional data is expected to improve the overall quality of the annual shorelines by providing cleaner and more stable annual layers.
-
-The integration of a new global tidal model (FES2014) may result in minor changes to the product’s historical coastlines and derived rates of coastal change. These changes are likely to be greatest in macrotidal regions of Australia such as north-western Western Australia and central Queensland. A comparison of annual shoreline accuracy at the microtidal Narrabeen Beach in Sydney shows consistent results between DEA Coastlines version 1.1.0 and the newer version 2.0.0.

 DEA Coastlines presents a historical record of coastal change since 1988 – it does not assign a reason or cause for coastal change or make predictions about future patterns or rates of coastal change.

 ## Changelog
 
+### DEA Coastlines 3.1.0 and 2025 annual data
+
+In April 2025, the DEA Coastlines product [was upgraded to version 3.1.0](https://github.com/GeoscienceAustralia/dea-coastlines/releases/tag/3.1.0). 
+This upgrade consists of the addition of interim annual shoreline data for 2025. The 2025 shoreline is interim data that is subject to change, and will be updated to a final version in the next DEA Coastlines upgrade (April 2027). You are now able to [access the latest data](./?tab=access) via DEA Maps and other methods. 
+
 ### 10 Sep 2025: DEA data in the Digital Atlas of Australia
 
 The [DEA Coastlines](/data/product/dea-coastlines/), [DEA Mangroves](/data/product/dea-mangroves/), and [DEA Water Observations Multi-Year Summary](/data/product/dea-water-observations-statistics-landsat/) datasets have now been added to the Digital Atlas, joining [DEA Land Cover](/data/product/dea-land-cover-landsat/). This integration marks a significant milestone in how DEA data can be accessed, visualised, and applied. By embedding DEA products into the Digital Atlas, users can now interact with trusted Earth observation datasets alongside other authoritative national data — unlocking powerful new opportunities for cross-sector analysis and decision-making.

+% ## Access constraints

+% ## Use constraints
+
+:::{dropdown} How to access the data
+DEA Coastlines data for the entire Australian coastline is available to download in two formats:
+
+* OGC GeoPackage (recommended): suitable for QGIS; includes built-in symbology for easier interpretation
+* Esri Shapefiles: suitable for ArcMap and QGIS
+
+To download DEA Coastlines data:
+
+1. Click the [Link to data](https://data.dea.ga.gov.au/?prefix=derivative/dea_coastlines/3-0-0/) link above
+1. Click on either the OGC GeoPackage (`coastlines_*.gpkg`) or Esri Shapefiles (`coastlines_*.shp.zip`) to download the data to your computer.
+1. If you downloaded the Esri Shapefiles data, unzip the zip file by right clicking on the downloaded file and selecting **Extract all**.
+
+To load OGC GeoPackage data in QGIS:
+
+1. Drag and drop the `coastlines_*.gpkg` file into the main QGIS map window, or select it using **Layer** &gt; **Add Layer** &gt; **Add Vector Layer**.
+1. When prompted to **Select Vector Layers to Add**, select all layers and then **OK**.
+1. The DEA Coastlines layers will load with built-in symbology. By default, DEA Coastlines layers automatically transition based on the zoom level of the map. To deactivate this: right click on a layer in the QGIS Layers panel, click **Set Layer Scale Visibility**, and untick **Scale visibility**.
+:::
+
+:::{dropdown} How to explore DEA Maps
+
+Start exploring [DEA Coastlines on DEA Maps](https://maps.dea.ga.gov.au/#share=s-DEACoastlines).
+
+Or, to add DEA Coastlines to DEA Maps manually:
+
+1. Open [DEA Maps](https://maps.dea.ga.gov.au/).
+2. Select **Explore map data** on the top-left.
+3. Select **Sea, ocean and coast** &gt; **DEA Coastlines** &gt; **DEA Coastlines**.
+4. Click the blue **Add to the map** button on top-right.
+
+By default, the map will show hotspots of coastal change at continental scale. Red dots represent retreating coastlines (e.g. erosion), while blue dots indicate seaward growth. The larger the dots and the brighter the colour, the more coastal change that is occurring at the location. 
+
+More detailed rates of change points will be displayed as you zoom in. To view a time series chart of how a coastal region or area of coastline has changed over time, click on any point (press **Expand** on the pop-up for more detail):
+
+![DEA Maps zoom example](/_files/dea-coastlines/DEACoastLines_DEAMaps_1.gif)
+
+Zoom in further to view individual annual shorelines:
+
+![DEA Maps coastlines example](/_files/dea-coastlines/DEACoastLines_DEAMaps_2.gif)
+
+**Note:** To view a DEA Coastlines layer that is not currently visible (e.g. rates of change points at full zoom), each layer can be added to the map individually from the **Sea, ocean and coast** &gt; **DEA Coastlines** &gt; **Supplementary data** directory.
+:::
+
+:::{dropdown} How to load data from the Web Feature Service (WFS) using Python
+DEA Coastlines data can be loaded directly in a Python script or Jupyter Notebook using the DEA Coastlines Web Feature Service (WFS) and `geopandas`:  
+
+```python
