kangas - 2.4.2
New in this release:
1. Added UMAP projection, with docs (use Embedding(projection="umap")); requires pip install umap-learn
2. Remove status check on debounce for filter bar, in UI
3. Put a timeout on downloads (any path that is http or https)
4. Fixed two bugs in dg.readcsv(): handle no headers, if converted raises, use None value
5. Adjust the size of points in thumbnail scatter plots of embeddings
6. Updated notebook `VisualizingembeddingsinKangas.ipynb
7. AddedEmbedding(scale=True)` for "umap" and "pca"

kangas - 2.4.0
New in this release:
- New auto dynamic update: a polling system that runs automatically for all DataGrid UIs, checking every 15 seconds if the underlying database has changed. If it has, then it smoothly will update the UI (unless a dialog window, like editing computed columns, is open).
- Removed the timestamp from the URL
- Added new expression function: HISTOGRAM({"Column Name"}, 10) that will return a number for that row representing the value in "Column Name" broken into 10 bins. Useful to group by this value to see the distribution of each bar in a histogram chart.
- Added selectable columns in all Python query APIs. By default, one gets all columns except "row-id". Use select="*" to get all columns, including "row-id". Otherwise, use select=["Column Name1", ...]
- Spellcheck turned off (again) in computed column editor
- Row-id cell shows "N/A" when grouping on another column.
- "About" markdown now automatically turns URLs into links
- Fixed a bug in "kangas upgrade" and "dg.upgrade()"
- Fixed a bug in appending data of wrong type (that was in the Getting Started notebook)
- Fixed loading spinner from flashing, and changing view
- Refactored embedding projector to handle large embedding vectors
