|
|
|
| ## v0.2.5 (2026-08-14)
|
|
|
| - Added the community contribution `samorzad_gov_pl` by Dawid Majewski
|
| (`dawidmajewski`): 72,771 Polish articles / 41,154,506 cl100k-proxy tokens
|
| from 246 local public institutions and one central platform tenant using the
|
| shared samorzad.gov.pl platform.
|
| - Converted the published, directly collected source dataset at revision
|
| `d5eaefc32c3f17cfa5a01d14573f8e4ee7d43385`; retained 72,771 of 81,422
|
| records after dropping 6,624 short, 35 below the Polish-language heuristic
|
| and 1,992 exact-duplicate records.
|
| - Preserved the human-readable publishing institution in every `author` value.
|
| Added a 72,771-record attribution sidecar with discovered source URLs,
|
| fetched final URLs, recommended attribution URLs, titles, institution names,
|
| license URLs and modification notices.
|
| - Added the frozen 247-institution publisher manifest, reproducible conversion
|
| script, contract tests, source datasheet, NOTICE and release-time license
|
| evidence. The live shared footer script matched the audited SHA-256
|
| `b36ec507901ed443195479d8d8009386159ae59d7486ce266bfb3308043e99aa`.
|
| - Recomputed complete-corpus totals: 4,319,200 documents and 9,639,062,573
|
| cl100k-proxy tokens across 18 sources.
|
|
|
| ## v0.2.4 (2026-08-07)
|
|
|
| - Expanded `european_hplt_v3_pl` (Arkadiusz Słota / `Maggio33`) from HPLT v3.0
|
| WDS quality bins 10+9 to **WDS bins 10-5**: +1,493,384 documents /
|
| 2,043,141,874 cl100k-proxy tokens, 100% CC0-1.0. The source total is now
|
| 1,603,974 documents / 2,555,525,652 tokens.
|
| - Phone PII-scrub hardening (v12b): an independent-lens deep verification caught
|
| a systematic phone recall-gap (~1,900 real phone numbers) that the pipeline's
|
| self-report (idempotency) was structurally blind to — address-block
|
| suppression, `dzwoń`-label family, leading-0 landline, `+48`-paren,
|
| newline-over-span and foreign-UK-bare formats. Fixed and dual-independently
|
| verified; the residual 0.0135% is a classified clearance-tail. Phones map to a
|
| `[Telefon]` semantic tag (anti-poisoning, not a fake number).
|
| - Cross-source deduplication of the expansion against the existing WDS-10+9
|
| shards: removed 3,038 near-duplicate documents (truncation variants);
|
| exact-dup 0, near-dup overlap 0.0000% (byte-verified). Resolves the
|
| "downstream near-dedup remains" caveat from the original release.
|
| - Contract-revalidated the merged parquet (canonical schema, non-empty text,
|
| positive token counts, uniform source/license, stats-file consistency).
|
| - Expanded contributor credit for Arkadiusz Słota (`Maggio33`) for the WDS 10-5
|
| expansion, PII-scrub and dedup work.
|
| - Updated the complete-corpus release totals from per-source parquet stats:
|
| 4,246,429 documents and 9,597,908,067 cl100k-proxy tokens (also reflects the
|
| separately-merged `biblioteka_nauki` source now present on main).
|
|
|
| ## v0.2.3 (2026-07-26)
|
|
|
| - Added the community contribution `european_hplt_v3_pl` by Arkadiusz Słota
|
| (`Maggio33`): HPLT v3.0 Polish WDS quality bins 10+9, 110,590 documents and
|
| 512,383,778 cl100k-proxy tokens under CC0-1.0 packaging.
|
| - Added the reviewed `global_voices` contribution by Dawid Majewski
|
| (`dawidmajewski`): 2,040 documents / 3,715,020 tokens with CC-BY-3.0 and
|
| per-document author attribution metadata.
|
| - Added `nkjp1m` from contributor `1am`: 18,381 documents / 2,601,201 tokens
|
| from the manually annotated 1-million-word NKJP subcorpus under the upstream
|
| version-unspecified CC-BY statement.
|
| - Revalidated the contributed parquet against the canonical schema, non-empty
|
| text, positive token counts, uniform source/license metadata, and stats-file
|
| consistency.
|
| - Updated the complete 16-source release totals from per-source parquet stats:
|
| 2,710,974 documents and 6,881,277,362 cl100k-proxy tokens.
|
| - Recomputed the full-corpus phrase-frequency report and charts. Updated the
|
| Arrow reporting path to use 64-bit string offsets for large row groups.
|
| - Fixed `src/test_hplt_v3_contract.py` to resolve its fixture relative to the
|
| repository instead of a contributor-local Windows path.
|
| - Added public contributor credit for Arkadiusz Słota (`Maggio33`) and Paweł
|
| Puzio (`ppuzio`, author of the `govpl` contribution released in v0.2.2), plus
|
| Dawid Majewski (`dawidmajewski`) for Global Voices Polish.
|
| - HPLT caveat: CC0 applies to the HPLT packaging; underlying web documents can
|
| carry independent rights. Downstream near-dedup and web-content review remain
|
| recommended before training.
|
|
|
| ## v0.2.2 (2026-07-19)
|
|
|
| - Added `govpl` — gov.pl Polish government press releases (CC-BY-SA-4.0),
|
| 88,190 documents / 80.7M tokens, fetched directly from gov.pl across 133
|
| ministry/agency subsites. New scripts: `src/discover_govpl.py` (discovers each
|
| subsite's news-section path into the committed `src/govpl_subsites.json`
|
| manifest) and `src/fetch_govpl.py` (pure-stdlib crawl of that manifest).
|
| - Stable totals after adding govpl: 13 sources, 2,579,963 docs, 6.36B tokens
|
| (tiktoken proxy).
|
| - Article date range 2005-09-26 → 2026-07-19. Build dropped 24 non-Polish and
|
| deduped 1,926 cross-posted articles (exact sha1).
|
|
|
| ## v0.3.1-preview (2026-07-10)
|
|
|
| - Added a separate 810-document Europeana direct-ingestion preview parquet at
|
| `previews/v0.3.1/europeana.parquet`. It was built from 1,000 live API records
|
| using per-record rights/creator metadata in 59.4 seconds; 808 retained records are Public
|
| Domain Mark and two are CC-BY-SA-4.0.
|
| - The direct source gate dropped 181 non-Polish and nine OCR-garble records.
|
| `dsbench` found unique IDs, no empty text, no duplicate text and no eval-set
|
| overlap. Potential-phone matches remain warnings for manual review.
|
| - This preview does not change v0.2.1 stable totals or promote Europeana to a
|
| stable source. It is the measured contract for the full rights-preserving run.
|
|
|
| ## v0.3.0-preview (in progress)
|
|
|
| - Validated the source-policy gate on live local SpeakLeash shards: 12 reviewed
|
| sources sampled and cleared blocking checks; four sources remain excluded and
|
| two talk-page shards remain on hold pending a separate policy.
|
| - Ran a direct Europeana 200-record rebuild probe with per-record rights and
|
| creator metadata: 197 Public Domain Mark and three CC-BY-SA-4.0 records
|
| cleared blocking validation. This is candidate validation, not a release
|
| inclusion.
|
| - Biblioteka Nauki direct probe currently returns HTTP 500 and is held out of
|
| the preview until the upstream request is repaired and audited.
|
|
|
| ## v0.2.1 (2026-07-02)
|
|
|
| - Released a stable metadata-schema update: `id, text, source, added, created, token_count, license, author`.
|
| - Current release totals after parquet recount: 12 sources, 2,491,773 docs, 6.28B tokens (tiktoken proxy).
|
| - Added `1000_novels` as a stable CC-BY-4.0 literature source.
|
| - Added source registry entries and PR contract for future `biblioteka_nauki` and `europeana` ingestion with per-document license/author metadata. These sources are not included in v0.2.1 parquets yet.
|
| - Credited Bart Kobyliński for source expansion work on Biblioteka Nauki and Europeana metadata/rebuild preparation.
|
| - Kept raw SpeakLeash Europeana excluded unless a direct rebuild preserves per-record rights metadata.
|
| - Sources: eurlex, parliamentary, wikisource, wikipedia, dziennik_ustaw, wolne_lektury, 1000_novels, wikiquote, eltec_pol, wikivoyage, wikibooks, wikinews.
|
| - Excluded (see README): open_subtitles_corpus, europeana_eu_pl_corpus_raw_speakleash, project_gutenberg_pl_corpus.
