 ## Changed
 
+- Removed `data.table` package dependency by leveraging `rlang::obj_address()` for generating ephemeral collection URIs.
 - `ManagedQuery` reuses the same buffers for each incomplete read and allocates dedicated buffers when converting to Arrow. ([#4299](https://github.com/single-cell-data/TileDB-SOMA/pull/4299))
 - Default log level changed from `info` to `warn` to reduce verbosity. Use `set_log_level("info")` or the `SPDLOG_LEVEL` environment variable to restore verbose logging. ([#4393](https://github.com/single-cell-data/TileDB-SOMA/pull/4393))

 ## .onLoad is called whether code from the package is used and the packages is 'loaded'. An
 ## example is calling `tiledbsoma::show_package_versions()`. So this is most elementary check,
 ## .onAttach is also called when the package is 'attached' via 'library(tiledbsoma)'
