 # Change Log
 
+## V10.1.0 - 2021-11-23
+
+This release includes patches for three security vulnerabilities:
+
+- Insecure default configuration affects installations where REDASH_COOKIE_SECRET is not set explicitly (CVE-2021-41192)
+- SSRF vulnerability affects installations that enabled URL-loading data sources (CVE-2021-43780)
+- Incorrect usage of state parameter in OAuth client code affects installations where Google Login is enabled (CVE-2021-43777)
+
+And a couple features that didn't merge in time for 10.0.0
+
+- Big Query: Speed up schema loading (#5632)
+- Add support for Firebolt data source (#5606)
+- Fix: Loading schema for Sqlite DB with "Order" column name fails (#5623)
+
+## v10.0.0 - 2021-10-01
+
+A few changes were merged during the V10 beta period.
+
+- New Data Source: CSV/Excel Files
+- Fix: Edit Source button disappeared for users without CanEdit permissions
+- We pinned our docker base image to Python3.7-slim-buster to avoid build issues
+- Fix: dashboard list pagination didn't work
+
+## v10.0.0-beta - 2021-06-16
+
+Just over a year since our last release, the V10 beta is ready. Since we never made a non-beta release of V9, we expect many users will upgrade directly from V8 -> V10. This will bring a lot of exciting features. Please check out the V9 beta release notes below to learn more.
+
+This V10 beta incorporates fixes for the feedback we received on the V9 beta along with a few long-requested features (horizontal bar charts!) and other changes to improve UX and reliability.
+
+This release was made possible by contributions from 35+ people (the Github API didn't let us pull handles this time around): Alex Kovar, Alexander Rusanov, Arik Fraimovich, Ben Amor, Christopher Grant, Đặng Minh Dũng, Daniel Lang, deecay, Elad Ossadon, Gabriel Dutra, iwakiriK, Jannis Leidel, Jerry, Jesse Whitehouse, Jiajie Zhong, Jim Sparkman, Jonathan Hult, Josh Bohde, Justin Talbot, koooge, Lei Ni, Levko Kravets, Lingkai Kong, max-voronov, Mike Nason, Nolan Nichols, Omer Lachish, Patrick Yang, peterlee, Rafael Wendel, Sebastian Tramp, simonschneider-db, Tim Gates, Tobias Macey, Vipul Mathur, and Vladislav Denisov
+
+Our special thanks to [Sohail Ahmed](https://pk.linkedin.com/in/sohail-ahmed-755776184) for reporting a vulnerability in our "forgot password" page (#5425)
+
+### Upgrading
+
+(This section is duplicated from the previous release - since many users will upgrade directly from V8 -> V10)
+
+Typically, if you are running your own instance of Redash and wish to upgrade, you would simply modify the Docker tag in your `docker-compose.yml` file. Since RQ has replaced Celery in this version, there are a couple extra modifications that need to be done in your `docker-compose.yml`:
+
+1. Under `services/scheduler/environment`, omit `QUEUES` and `WORKERS_COUNT` (and omit `environment` altogether if it is empty).
+2. Under `services`, add a new service for general RQ jobs:
+
+```yaml
+worker:
+  <<: *redash-service
+  command: worker
+  environment:
+    QUEUES: "periodic emails default"
+    WORKERS_COUNT: 1
+```
+
+Following that, force a recreation of your containers with `docker-compose up --force-recreate --build` and you should be good to go.
+### UX
+- Redash now uses a vertical navbar
+- Dashboard list now includes “My Dashboards” filter
+- Dashboard parameters can now be re-ordered

+- On the queries list view “My Queries” has moved above “Archived”
+- Improved behavior for filtering by tags in list views
+- When a user’s session expires for inactivity, they are prompted to log-in with a pop-up so they don’t lose their place in the app
+- Numerous accessibility changes towards the a11y standard
+- Hide the “Create” menu button if current user doesn’t have permission to any data sources
+

+- Fix: numerical comparisons failed if value from query was a string
+
+### Parameters
