Additional notes

Major release - see our blog. Significant changes as follows. See also comprehensive note of changes.

Added

Larger prediction jobs: chunked prediction with progress updates and runtime estimates, individual chunks that can be processed across machines, and optional direct Parquet materialisation in DuckDB to reduce memory pressure.
Incremental linkage and pairwise scoring: experimental predict_within() and predict_between() methods score new or selected datasets, while score_pair() and score_pairs() score individual pairs or all pairs between two collections.
SQL pipeline profiling: detailed per-query profiles for DuckDB and Spark help identify expensive stages of a linkage job.

Changed

Faster training and blocking analysis: u estimation uses chunks and can stop once comparison levels have enough observations; EM training supports a max_pairs cap; prior estimation and blocking analysis support record sampling. Blocking counts are sampled by default, with exact counts still available.
Explicit input registration: register inputs with db_api.register() before passing them to Linker; the constructor no longer takes db_api=. query_sql() returns a SplinkDataFrame by default, and as_record_dict() is renamed to as_record_list().
Smaller installation: only DuckDB, PyArrow, and SQLGlot are required at runtime. Pandas, NumPy, Altair, and igraph are optional; install splink[igraph] when the is_bridge edge metric is needed.
Charts without Altair: charts and column profiles use SplinkChart, with native notebook display and HTML export, including offline HTML. Install splink[altair] for Altair customisation and advanced exports; Jinja2 is no longer required for chart or dashboard rendering.
More stable scoring: probabilistic calculations use match weights (log-odds), with output prefixes changing from bf_ to mw_. bayes_factor_column_prefix is deprecated in favour of match_weight_column_prefix.
Date-of-birth comparisons: DateOfBirthComparison uses standard Levenshtein distance on all supported backends. Transposed digits may fall into a different comparison level when rebuilding a model from the template.

Removed

Python 3.9 and Amazon Athena support. Splink 5 requires Python 3.10 or later.
Legacy inference methods compare_two_records() and find_matches_to_new_records(), implicit caching and use_cache, salting, the materialise_blocked_pairs argument, and the exploratory similarity-analysis helpers. See the comprehensive note for replacements and migration details.

Fixed

Updated .jar (0.2.1) with newer dependency versions #3098
