-### 1.1.2 (unreleased)
+### 1.2.0 (unreleased)
+
+#### Added
+
+-   Add new experimental functional API for hyperparameter tuning with
+    {func}`scvi.autotune.run_autotune` and {class}`scvi.autotune.AutotuneExperiment` to replace
+    {class}`scvi.autotune.ModelTuner`, {class}`scvi.autotune.TunerManager`, and
+    {class}`scvi.autotune.TuneAnalysis` {pr}`2561`.
+-   Add experimental class {class}`scvi.nn.Embedding` implementing methods for extending embeddings
+    {pr}`2574`.
+-   Add experimental support for representing batches with continuously-valued embeddings by passing
+    in `batch_representation="embedding"` to {class}`scvi.model.SCVI` {pr}`2576`.
+-   Add experimental mixin classes {class}`scvi.model.base.EmbeddingMixin` and
+    {class}`scvi.module.base.EmbeddingModuleMixin` {pr}`2576`.
+
+#### Changed
+
+-   Deprecate {func}`scvi.data.cellxgene`, to be removed in v1.3. Please directly use the
+    [cellxgene-census](https://chanzuckerberg.github.io/cellxgene-census/) instead {pr}`2542`.
+
+#### Removed
+
+-   Remove {class}`scvi.autotune.ModelTuner`, {class}`scvi.autotune.TunerManager`, and
+    {class}`scvi.autotune.TuneAnalysis` in favor of new experimental functional API with
+    {func}`scvi.autotune.run_autotune` and {class}`scvi.autotune.AutotuneExperiment` {pr}`2561`.
