#2529 Topic deletion fails if topics have custom lables

#2423 BadRequestError: Error code: 400 - {'error': {'message': "Unsupported parameter: 'stop' is not supported with this model.", 'type': 'invalid_request_error', 'param': 'stop', 'code': 'unsupported_parameter'}}

#2531 Topic aspects are not updated when merging topics and the model uses a custom vectorizer

#2530 Creating topics over time fails if model has deleted topics

#2526 Creating Topic Taxonomies

#2523 Add structured multi aspect output to the LangChain representation 2:06 AM

#2236 Better Topic Modeling Visualization/Saving for Image Only Analysis

#2498 `MaximalMarginalRelevance` makes 2N embedding calls instead of 1

#2508 Add top-down (divisive) strategy for `hierarchical_topics()`

#2507 Support pre-tokenized documents to avoid redundant tokenization across pipeline stages

#2506 Add contrastive and embedding-aware feature importance as representation aspects

#2505 Lightweight soft topic assignment via temperature-scaled embedding distances

#2504 Support reusing pre-computed UMAP embeddings across runs (grid search, caching)

#2503 `hierarchical_topics()` parent nodes show raw c-TF-IDF keywords instead of representation model labels

#2502 `approximate_distribution`: add target-based min_similarity ("at most N unassigned documents")

#2501 `reduce_outliers`: add target-based outlier reduction ("reduce to X% outliers")

#2500 Allow recalculating representative docs with a configurable count (currently hardcoded to 3)

#2499 `_extract_representative_docs` recomputes from scratch on every call — no caching

#2497 Extract duplicated document-aggregation and topic-naming patterns into shared helpers

#2492 `_extract_representative_docs` uses text-based `in` matching, causing wrong documents when duplicates exist

#2495 `_extract_representative_docs`: duplicate sampling (`replace=True`) and text-based index mapping select wrong documents

#2491 `_extract_representative_docs` samples with `replace=True`, producing duplicate representative documents

#2154 Custom labels in dynamic modeling and topic per class

#2493 BERTopic.load(path, embedding_model=...) makes a redundant HuggingFace network request even when an embedder is explicitly provided

#2485 ci: add uv_exclude_newer env in github actions workflow?
