 ## Version 1.1.0 Release Notes
 
-* __[Bug] Restore timeline legacy functions and filters__
+* __[1.1] Fix yarn build docs and update test (#844)__

-    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.
+    yarn build flags in /src/dev/build/cli.ts are not updated to match the renamed flags in de-couple PR (#795). This PR fixes the issue
+    and update the tests. Also modify words in DEVELOPER_GUIDE.md.

+* __[1.1] De-Couple Dashboards linux building process (#843)__

+    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`.

-    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.
+* __[1.1][Bug] Restore timeline legacy functions and filters__
 
-    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.

+    
+    Finally, the key was incorrect for actually accessing the filter so it never
+    applied the filters in the default state.
