Changelog May 2021
Welcome to Render's May 2021 changelog! Going forward we will keep you updated on all the features, bug fixes, and improvements we're working on by publishing this document once a month. We hope it's useful as you grow your applications and businesses on Render; do send us suggestions for things you'd like us to include here going forward.
Feature Spotlight
You can now automatically scale your services up and down based on target CPU and memory utilization.
Many services handle variable load: you might see regular increases in usage during the day, or a surge after launching a new feature. Autoscaling makes it possible to keep your services scaled to your needs without manual configuration. Check out the docs to get started.
Read Replicas
You can now add read replicas to your Render PostgreSQL databases.
Read replicas reduce load on your primary database and make one-off queries safer. They are also a great option for data analysis tools that do not need to write to your primary database, or for running computationally expensive data analysis without impacting the performance of you primary instance. Read replicas are available on Standard database plans and above. Check out the docs to get started.
  • You can now view additional database metrics for storage, active connections, and replication lag (if read replicas are enabled). For Standard database plans and above, you can select a time range to view database metrics.
  • You can now trigger a database backup manually, and view backups in progress (docs).
  • Trial users can now use Render disks up to 1 GB without adding a credit card.
  • All environments now include magic-wormhole to transfer files to and from Render Disks using the web shell.
  • We are rolling out dashboard notifications in the form of toasts. New users will see them first after email confirmation.
  • You can now skip an auto-deploy by including a skip phrase in the commit message.
  • You can now zoom into CPU and memory graphs on the dashboard.
  • You can now manage your custom domains with Render's REST API. This functionality is stable, but is in early access while we build out other API endpoints; please email to get access.
Fixes and Improvements
  • We've improved the reliability, security, and performance for our Frankfurt infrastructure by increasing capacity, upgrading infrastructure components, and implementing encryption-at-rest for control plane data.
  • We also published a detailed root cause analysis document for the May 6th incident affecting Frankfurt services. You can view it on the May 6th incident status page.
  • We've hardened our SSL certificate renewal infrastructure to prevent certificates from expiring in a few specific cases.
  • Docker image builds now use buildkit v0.8.2 (previously v0.7.2).
  • Manually clearing the cache for static sites will now reliably remove all cached artifacts.
  • We've improved error messages related to GitHub connection issues.
  • We've added more compute capacity to power our (early access) REST API endpoints. This will make API calls faster and more reliable.
  • We've made it easier to fix errors during service creation by automatically scrolling to the invalid field(s) in the dashboard.
  • We've made it easier to read the the billing table when using screen readers.
  • Fixed an issue where databases in an error state displayed an internal server error in the dashboard. These databases are now displayed with an unknown status.
  • Fixed an issue where some database backups on Starter plans were failing.
  • Fixed an issue where we displayed the incorrect due date on invoices.
  • Fixed an issue where we incorrectly displayed services when an error occurred.
  • Fixed an issue where we failed to resume suspended services in Frankfurt after users updated their payment information.
  • We have disabled Render Addons. We used Manifold to provision Addons behind the scenes. Unfortunately, Manifold shut down operations in May 2021. All existing users should have already migrated their Render Addons using our migration docs.
Create multiple environments from the same YAML file
Feature update! You can now create multiple environments from the same YAML through your Render dashboard.
Render Community Forum Live!
As our user base has grown, we've approached the limits of Slack as a Q&A and help forum. We will be transitioning to a real forum for most interactions that don't involve emailing, and you can get early access to it today by signing up at
Why you should use the forum instead of Slack:
  • Your messages won't get lost in the barrage of Slack conversations: like with the Slack community, Render engineers will monitor and respond to posts in the community forum.
  • It's a lot easier to have asynchronous conversations on a post vs. on a Slack thread, and even easier if you have multiple ongoing conversations with Render.
  • You will get notified via email or an optional desktop notification when someone responds to a post. No need to keep checking Slack for a response.
  • There are no history limits, so all questions will always be available and searchable.
  • You can get alerted to new topics weekly/daily, just like with
  • You can still have DMs with Render engineers in the community forum.
We'd love for you to try it out today!
Automatic preview environments
Automatic preview environments are in GA!
Automatic preview environments enable you to generate a complete replica of your production infrastructure for every pull request in your GitHub/GitLab repositories.
yaml-file (1)
Test with precision and confidence, share upcoming and proposed changes with product and marketing, create sandboxes for sales demos, and reproduce user issues in a live production-like environment.
Improved resiliency to traffic spikes and DDoS attacks
We've revamped Render's global load balancing code to be much more resilient to traffic spikes and DDoS attacks.
Suspend and Resume Databases
You can now suspend and resume databases from the dashboard.
To suspend a database use the Suspend Database button located below the Access Control section.

Suspended Databases can be resumed at any time using the Resume Database button.

Database Access Controls
You can now restrict public access to your Render databases. Allow only trusted IPs or block external access completely.
New Guides and One-Click Deploys
We’ve created in-depth guides to deploy your Django and Ruby on Rails projects on Render! We’ve also created a number of one-click deploy buttons for popular open-source analytics projects that will provide critical business insights in just a couple minutes!
EU Region now generally available!
We're super excited to announce general availability of our first Europe region in Frankfurt.
Certificate Status for Custom Domains
You can now see the status of your custom domain SSL certificates once DNS verification is complete.
This is what it looks like after DNS has been verified and the certificate is pending issuance:
And this is the all clear screen:
