 # Learning Interpretability Tool Release Notes
 
+## Release 1.1
+
+This release provides the capabilities to interpret and debug the behaviors of
+Generative AI models in LIT. Specifically, we added sequence salience, which
+explains the impact of the preceding tokens on the generated tokens produced by
+the GenAI models. Major changes include:
+* An `LM salience` module in the LIT UI that computes generations, tokenization,
+and sequence salience on-demand;
+* Computation of sequence salience at different granularities, from the smallest
+possible level of tokens, to more interpretable larger spans, such as words,
+sentences, lines, or paragraphs.
+* Support of OSS modeling frameworks, including KerasNLP and Hugging Face
+Transformers for sequence salience computation.
+This release would not have been possible without the work of our contributors.
+Many thanks to:
+[Ryan Mullins](https://github.com/RyanMullins),
+[Ian Tenney](https://github.com/iftenney),
+[Bin Du](https://github.com/bdu91), and
+[Cibi Arjun](https://github.com/cpka145).

+Transformers.
+
+Sequence salience in the LIT UI provides multiple options for analysis,
+including:
+
+*   running the salience methods on the text from the dataset (target) or from
+    the model (response).
+*   computing the sequence salience through [Gradient Norm](#gradient-norm) or
+    [Gradient-dot-Input](#gradient-dot-input).
+*   selecting different granularity levels for salience analysis, from the
+    smallest possible level of tokens, to more interpretable larger spans, such
+    as words, sentences, lines, or paragraphs.
