 ## [2.2.0] - 2024-07-12
 ### Changed
 - Switched from having `chunkerify()` output a function to having it return an instance of the new `Chunker()` class which should not alter functionality in any way but will allow for the preservation of type hints, fixing [#7](https://github.com/umarbutler/semchunk/pull/7).

 ### Added
 - Added the `chunk()` function, which splits text into semantically meaningful chunks of a specified size as determined by a provided token counter.

 `semchunk` is a fast and lightweight Python library for splitting text into semantically meaningful chunks.
 
-Owing to its complex yet highly efficient chunking algorithm, `semchunk` is both more semantically accurate than [`langchain.text_splitter.RecursiveCharacterTextSplitter`](https://python.langchain.com/v0.2/docs/how_to/recursive_text_splitter/#splitting-text-from-languages-without-word-boundaries) (see [How It Works 🔍](https://github.com/umarbutler/semchunk#how-it-works-)) and is also over 90% faster than [`semantic-text-splitter`](https://pypi.org/project/semantic-text-splitter/) (see the [Benchmarks 📊](https://github.com/umarbutler/semchunk#benchmarks-)).

 ## Benchmarks 📊
-On a desktop with a Ryzen 3600, 64 GB of RAM, Windows 11 and Python 3.11.9, it takes `semchunk` 6.69 seconds to split every sample in [NLTK's Gutenberg Corpus](https://www.nltk.org/howto/corpus.html#plaintext-corpora) into 512-token-long chunks with GPT-4's tokenizer (for context, the Corpus contains 18 texts and 3,001,260 tokens). By comparison, it takes [`semantic-text-splitter`](https://pypi.org/project/semantic-text-splitter/) 116.48 seconds to chunk the same texts into 512-token-long chunks — a difference of 94.26%.
+On a desktop with a Ryzen 9 7900X, 96 GB of DDR5 5600MHz CL40 RAM, Windows 11 and Python 3.12.4, it takes `semchunk` 2.87 seconds to split every sample in [NLTK's Gutenberg Corpus](https://www.nltk.org/howto/corpus.html#plaintext-corpora) into 512-token-long chunks with GPT-4's tokenizer (for context, the Corpus contains 18 texts and 3,001,260 tokens). By comparison, it takes [`semantic-text-splitter`](https://pypi.org/project/semantic-text-splitter/) (with multiprocessing) 25.03 seconds to chunk the same texts into 512-token-long chunks — a difference of 88.53%.
