Jan 1, 2026January 2026 (IBM/unitxt) focused on release readiness through a structured version bump. Bumped the release version from 1.26.7 to 1.26.9 via two commits: ea47e517322d25f5689b7de7ebe3b6b18a50f24f (Update version to 1.26.8) and 20b951e5bd109cd43018f33018dfc7b3dbff3c9f (Update version to 1.26.9). No major bugs fixed in this period; the work centered on establishing a stable release baseline, aligning versioning, and preparing the 1.26.9 release for QA and deployment. This contributes to predictable upgrade paths for customers and reduces release risk by ensuring versioning is clear and verifiable.

Jul 1, 2025July 2025 deliverables for IBM/unitxt focused on usability, performance, and reliability. Key highlights include comprehensive documentation updates for metrics and F1 to improve user understanding, reproducible experimentation enhancements, and performance/risk reductions across the pipeline. Specifically, metrics documentation clarifies purposes, ranges, and references (e.g., Normalized SacreBLEU, F1 in F1Fast) to reduce misinterpretation. A reproducible sampling seed (demos_sampling_seed) was added to DatasetRecipe and propagated through sampler classes to ensure consistent demo selection in experiments. Multi-threading enhancements speed up data processing with tests for thread safety and cache management. A new Temporal Reasoning Dataset (tot) expands evaluation coverage for semantic and arithmetic tasks. Optional tokenizer_name support was added to base HF inference engines to increase model-tokenization flexibility. Major release hygiene was maintained through version bumps to 1.26.x to align dependencies and compatibility. Critical fix: SQLite3 import reliability fix by removing the optional dependency to ensure consistent imports. These efforts collectively improve usability, reproducibility, performance, and reliability, accelerating experimentation and model evaluation in production workflows.
