 # Changelog
 
+## v0.3.0-preview (2026-06-16)
+
+- Added v0.3 quality/diversity workflow documentation: cap legal/parliamentary/official-document sources, use source-level temperature sampling, and evaluate per-source perplexity/style contamination.
+- Added source candidate review artifacts for contemporary Polish web and other possible additions.
+- Reviewed TVP Info-derived news data and blocked it until explicit upstream open-license evidence or permission is available.
+- Added European HPLT Polish web filtering workflow:
+  - `src/filter_european_hplt.py` supports chunked parquet output, explicit `HF_TOKEN`, and filtering specific HF parquet data files.
+  - `src/launch_hplt_parallel.py` launches parallel workers across the actual HF train shard list.
+- Current local HPLT candidate snapshot: 565,827 documents, 496,457,232 estimated tokens, about 1.0 GB compressed parquet output. This is not yet merged into the stable v0.2 parquet release.
+- Added `.gitignore` entries to keep large local generated candidates and logs out of git/HF commits.

 ## v0.2.0 (2026-06-15)
 
 - Initial release: 11 openly-licensed sources, 2,490,773 docs, 6.22B tokens (tiktoken proxy).
