Update to Fedora 44: sentencepiece addresses CVE-2026-1260 with significant security improvements.
Update to 0.2.1

Summary

The SentencePiece is an unsupervised text tokenizer for Neural Network-based

text generation.

It is an unsupervised text tokenizer and detokenizer mainly for

Neural Network-based text generation systems where the vocabulary size is

predetermined prior to the neural model training.

SentencePiece implements subword units and unigram language model with the

extension of direct training from raw sentences.

SentencePiece allows us to make a purely end-to-end system that does not

depend on language-specific pre/post-processing.
