 ## [Unreleased]
 
+## [v3.0.0-dev.8] - 2021-12-31
+
+- Add ``PluginFeatureDetection`` and disable WBOIT in Safari 15.
+- Add ``disable-wboit`` Viewer GET param
+- Add ``prefer-webgl1`` Viewer GET param
+- [Breaking] Refactor direct-volume rendering
+    - Remove isosurface render-mode (use GPU MC instead)
+    - Move coloring into theme (like for other geometries/renderables)
+        - Add ``direct`` color type
+        - Remove color from transfer-function (now only alpha)
+        - Add direct-volume color theme support
+        - Add volume-value color theme
+- [Breaking] Use size theme in molecular/gaussian surface & label representations
+    - This is breaking because it was hardcoded to ``physical`` internally but the repr size theme default was ``uniform`` (now ``physical``)
+
+## [v3.0.0-dev.7] - 2021-12-20
+
+- Reduce number of created programs/shaders
+    - Support specifying variants when creating graphics render-items
+    - Change double-side shader param from define to uniform
+    - Remove dMarkerType shader define (use uMarker as needed)
+    - Support to ignore defines depending on the shader variant
+    - Combine pickObject/pickInstance/pickGroup shader variants into one
+    - Combine markingDepth/markingMask shader variants into one
+    - Correctly set shader define flags for overpaint, transparency, substance, clipping
+- [Breaking] Add per-object clip rendering properties (variant/objects)
+    - ``SimpleSettingsParams.clipping.variant/objects`` and ``RendererParams.clip`` were removed
+
+## [v3.0.0-dev.6] - 2021-12-19
+
+- Enable temporal multi-sampling by default
+    - Fix flickering during marking with camera at rest
+- Enable ``aromaticBonds`` in structure representations by default
+- Add ``PluginConfig.Structure.DefaultRepresentationPreset``
+- Add ModelArchive support
+    - schema extensions (e.g., AlphaFold uses it for the pLDDT score)
+    - ModelArchive option in DownloadStructure action
+    - ``model-archive`` GET parameter for Viewer app
+    - ``Viewer.loadModelArchive`` method
+- Improve support for loading AlphaFold structures
+    - Automatic coloring by pLDDT
+    - AlphaFold DB option in DownloadStructure action
+    - ``afdb`` GET parameter for Viewer app
+    - ``Viewer.loadAlphaFoldDb`` method
+- Add QualityAssessment extension (using data from ma_qa_metric_local mmcif category)
+    - pLDDT & qmean score: coloring, repr presets, molql symbol, loci labels (including avg for mutli-residue selections)
+    - pLDDT: selection query
+- Warn about erroneous symmetry operator matrix (instead of throwing an error)
+- Added ``createPluginUI`` to ``mol-plugin-ui``
+    - Support ``onBeforeUIRender`` to make sure initial UI works with custom presets and similar features.
+- [Breaking] Removed ``createPlugin`` and ``createPluginAsync`` from ``mol-plugin-ui``
+    - Please use ``createPluginUI`` instead
+- Improve aromatic bonds handling
+    - Don't detect aromatic bonds for rings < 5 atoms based on planarity
+    - Prefer atoms in aromatic rings as bond reference positions
+
+## [v3.0.0-dev.5] - 2021-12-16
+
+- Fix initial camera reset not triggering for some entries.
+
+## [v3.0.0-dev.4] - 2021-12-14
+
+- Add ``bumpiness`` (per-object and per-group), ``bumpFrequency`` & ``bumpAmplitude`` (per-object) render parameters (#299)
+- Change ``label`` representation defaults: Use text border instead of rectangle background
+- Add outline color option to renderer
+- Fix false positives in Model.isFromPdbArchive
+- Add drag and drop support for loading any file, including multiple at once
+    - If there are session files (.molx or .molj) among the dropped files, only the first session will be loaded
+- Add drag and drop overlay
+- Safari 15.1 - 15.3 WebGL 2 support workaround
+- [Breaking] Move ``react`` and ``react-dom`` to ``peerDependencies``. This might break some builds.
+
+## [v3.0.0-dev.3] - 2021-12-4

+
+- Fix: allow atoms in aromatic rings to do hydrogen bonds
+
+## [v2.4.0] - 2021-11-25
+
+- Fix secondary-structure property handling
+    - StructureElement.Property was incorrectly resolving type & key
+    - StructureSelectionQuery helpers 'helix' & 'beta' were not ensuring property availability
+- Re-enable VAO with better workaround (bind null elements buffer before deleting)
+- Add ``Representation.geometryVersion`` (increments whenever the geometry of any of its visuals changes)
+- Add support for grid-based smoothing of Overpaint and Transparency visual state for surfaces
+
+## [v2.3.9] - 2021-11-20
