+* __[1.1] De-Couple Dashboards linux building process (#843)__
+
+    [Anan](mailto:[email protected]) - Tue, 5 Oct 2021 11:44:48 -0700
+
+    When running yarn build --skip-os-packages it will build 4 tarballs for Dashboards (2x linux, 1x macOS, 1x windows) and takes 10+min to do so.
+
+    In this PR, we break the building process to allow single linux to build. If run `yarn build-platform --linux-x64` only linux x64 tarball is created. Same for linux arm64 and darwin x64. You could run `yarn build-platform
+    --linux-arm64` and `yarn build-platform darwin-x64`.
+
+    partially solved:

+* __[1.1][Bug] Restore timeline legacy functions and filters__
+
+    [Kawika Avilla](mailto:[email protected]) - Tue, 28 Sep 2021 12:38:11 -0700
+
+    While renaming we changed values from legacy naming schema to OpenSearch
+    Dashboards naming schema. However, after realizing we impacted backwards
+    compatibility, we restored some of the
+    "under the hood" components backed to legacy application to allow for seemless
+    migration.
+
+    However, upon attempting to restore Timeline to work with saved objects we
+    neglected to restore the Timeline functions.
+
+    Previously users could set kibana=false to ignore filters on the dashboards
+    being applied to their Timeline visualizations. Now, if users tried to set it
+    then it would fail because it didn't know what that function was.
+
+    This commit fixes this issue by keeping the update since we do not want to
+    impact people who have now updated their functions and re-added the legacy
+    functions.
+
+    In this commit, I also restore the aliases for "elasticsearch" and now included
+    "opensearch" for Timeline queries.
+
+    Finally, the key was incorrect for actually accessing the filter so it never
+    applied the filters in the default state.
