Release Notes
November 22, 2024
Bring Devin into conversations just as you would with human teammates
Tag @Devin on bug reports and feature requests directly on Slack:
- Devin pulls in context automatically
- Message Devin from your phone
- All Slack sessions also link to a webapp session
Recent improvements to our Slack integration:
- Say “sleep” to put Devin to sleep. Devin only wakes up again when you tag @Devin in thread
- Say “archive” to put Devin to sleep + archive the session
- Turn on Slack notifications in sessions started from the webapp, you’re now able to (1) interact with Devin in Slack (2) receive updates in the Threads section of Slack
Devin responds to PR comments and lint errors automatically
Ask Devin to create a PR! Recent improvements to our PR workflow:
- When the PR receives comments or fails lint, Devin will automatically wake up to address it if it’s sleeping
- Click “PR Preview” under the session title to see the changes Devin has made before a PR has been created. If Devin makes edits, you’ll see a “Jump to Latest” button appear in the top right
Use Devin as your todo list
Try sending tasks to Devin as they come up, instead of adding them to your todo list. Hide completed sessions with the new archive button next to the session title.
Archived sessions show up under Folder > Archived in the left sidebar.
Configure Devin’s Behaviors
Configure Behavior in Settings to customize Devin’s behavior to your needs. These settings are user-specific and will not affect other users in your organization.
The first behavior you can now configure is Agency.
When Devin detects a task that requires codebase information, it will begin by investigating the repo and creating a plan. When Agency is turned on, Devin will proceed with its plan without waiting for your approval. Devin will always ask you whether you want to override this per-session.
Configure Devin’s Workspace
Devin’s Workspace resets to a saved machine state at the start of every session. By default this machine state includes all the repositories you’ve added and set up at preview.devin.ai/workspace.
Tip: Setting up Devin’s Workspace significantly improves Devin’s performance on your codebase. Imagine if every time you started a task, your laptop and part of your memory were wiped - that’s what happens to Devin without setup!
Behind the scenes, all repositories you set up co-exist on the same (default) machine snapshot. Advanced users can create additional machine snapshots to start Devin sessions from different saved machine states. Learn more in our docs.
Bulk import secrets
If your repo requires many secrets, share them with Devin in bulk in the Secrets section of settings — coming soon to the repo onboarding workflow.
Faster navigation with cmd-k
Use cmd-k to quickly start a new session and navigate the web applications
Talk to Devin from your IDE (Beta Access)
Handoff async work to Devin while you focus on your primary task. Review when convenient.
- Works in conjunction with Copilot and Cursor
- Devin’s just a shortcut away (Cmd+G)
- Keep track of your active Devins
- Review and accept code directly in your local IDE
Install the Devin Extension to get started.
Use macros to easily attach Playbooks (from Slack, Devin IDE, or webapp)
A macro is a shortcut (e.g. !macro) that can be used to quickly attach a Playbook to your initial prompt to Devin. Navigate to your Playbook in your Library and click “Edit” to set the macro for each Playbook.
November 5, 2024
Planning mode
For certain tasks, much of the work needed is figuring out what should be done and aligning on the approach. Devin will now automatically detect more complex tasks and spend time proposing a plan before beginning execution.
You can always auto-approve the plan if you don’t want Devin to wait for your approval.
November 1, 2024
Programmatically create Devin sessions and retrieve results (including strutured output) using our new REST API
Our new RESTful API allows you to integrate Devin into your own applications, write scripts to kick off multiple sessions in parallel, and build powerful automation workflows on top of Devin.
You’ll be able to specify a structured output format in your prompt, for example:
View structured output in the web app on any session page with CMD+i, or click “Show structured IO” in the dropdown menu in the top right corner of your chat.
You can obtain an API key from your settings page.
Read our external API docs to learn more and view an example of how to use the API.
It’s now easier to understand what Devin’s been up to with the “Follow Devin” tab.
The “Follow Devin” tab is designed to make it faster to understand what Devin’s been up to - it highlights Devin’s actions (file edits, shell commands, etc) as Devin works. Click on the magnifying glass icon to jump to the associated tool (editor, shell, browser, planner) for more information.
To be successful with Devin, upfront investment is usually required - our new Onboarding Flow walks you through the required steps
Onboarding steps include:
- Connecting your Github organization - this enables Devin to scan your codebase and generate Repo Knowledge. Github also enables Devin create PRs and respond to your PR comments automatically!
- Connecting your Slack organization allows you to kick off sessions and respond to Devin in the same place where you interact with your human teammates! Next time someone reports a frontend bug, try tagging @Devin in the channel to address it!
- Manually setting up Devin’s machine. If your repository requires developers to have environment variables or dependencies installed, it’s important to set up Devin’s machine. Otherwise, Devin will spend its limited resources figuring out setup before it’s able to tackle the task you give it.
You’ll receive warnings if Devin is about to sleep
Previously, users on our Personal and Team plans might’ve noticed that Devin may sleep unexpectedly. This is now fixed, and if Devin is about to sleep because it’s low on ACUs or close to per-session ACU limits (which reset with each new instruction and can be configured in Settings > Usage), you’ll receive a toast notification in the web app!
Repo knowledge
Devin will now automatically scan your repositories and generate Repo Knowledge. This allows Devin to more quickly and successfully do real work for you in your repo. You can always add and edit your own Knowledge manually in Settings > Knowledge
Increased options for Enterprise users
Enterprise users now have more options to configure Devin to meet your organization’s needs, including:
- Single sign-on with Okta
- Auto-Join for Company Domains: Allow any user with a company email to join Devin without individual invites
- Customized Onboarding: Tailor example sessions and suggested prompts to guide your organization’s users to Devin’s most valuable use cases
- Usage Insights: Automated email alerts to track your usage over time
October 10, 2024
A new home page, designed for longer prompts and smaller screens
Devin often works best when you share detailed context and requirements upfront. With our redesigned home page, the input box expands as you type and feels more like a file editor:
- press Enter for new lines
- use Cmd + Enter (or Ctrl + Enter) to send your message
- paste example code snippets or lists of requirements to try our rich text features
[Beta] Devin API
The Devin API allows you to spin up Devin sessions programmatically. Use cases range from automatic PR reviews and lint error resolution to providing internal services for migrations. Currently available for our Enterprise users - contact us at support@cognition.ai to learn more!
Faster session and workspace navigation
It’s now much faster to scrub Devin’s workspace, switch sessions, and start new sessions in the Devin web app.
We’ve migrated our authentication system to Auth0
You’ll notice a new design on our login page, but you’ll be able to log in as normal using your email, Google, or GitHub credentials.
September 26, 2024
Introducing Devin for Teams
With our Team plan, your entire team can create, share and collaborate together in Devin sessions. The Team plan includes everything in the Personal plan, plus:
- Unlimited seats
- Access to our Slack integration
- A larger ACU (Agent Compute Unit) capacity included with your monthly subscription
- A dedicated workspace for your team to create, share, and collaborate in Devin sessions together
Contact us at support@cognition.ai to learn more!
September 3, 2024
Devin responds to comments on PRs
Try reviewing Devin’s code via Github or Github Mobile — Devin will automatically respond as long as the session hasn’t ended and Devin isn’t sleeping.
Devin suggests Knowledge
Try giving Devin feedback in chat! Devin will automatically suggest new additions to Knowledge if something seems useful for future sessions.
Knowledge is a collection of tips, documentation, and instructions that Devin “knows” across all future sessions. Devin will automatically recall relevant Knowledge as necessary, and you can always manually add or review Knowledge in Settings & Library > Knowledge.
Let Devin create Devins with MultiDevin
Tackle large backlogs of tasks by delegating to a team of Devins that work in parallel. MultiDevin consists of 1 “manager” Devin and up to 10 “worker” Devins.
The manager Devin distributes a task to each worker Devin, then merges the changes from all successful worker Devins into one branch or pull request. MultiDevin is great for repeated, isolated tasks like lint errors, code clean-ups, migrations, refactors, and more!
Enterprise VPC Deployment
Devin offers an enterprise deployment option tailored for organizations with stringent security and compliance requirements. Our cloud-agnostic solution allows Devin to deploy DevBoxes within your own Virtual Private Cloud (VPC) and to store data within your cloud, ensuring your data remains exclusively within your controlled environment.
“Wake up” old Devin sessions
Previously, Devin sessions ended after long periods of inactivity. Now, most sessions will “sleep” instead, meaning that you can wake Devin up and resume the session at any point.
You can still end sessions manually with the “stop” button at the top right corner of the chat.
Send Devin code reviews in product
Ask Devin questions or ask for edits to specific lines of code. The code you comment on will be sent to Devin in one chat message.
Simply highlight any text in Devin’s editor and click “Add to chat” or “Add a comment”.
July 15, 2024
Universal Planner
With Universal Planner, Devin can now more reliably perform long, multi-step tasks that require looping — in other words, tasks that require performing the same action multiple times — without needing to use Playbooks.
Playbooks are still recommended for tasks and prompts that will be run multiple times or prompts that are helpful to share with your team.
Devin got smarter!
Many of our improvements this week have been behind the scenes improvements to Devin’s instruction following, editing, planning, and speed:
📚 Playbooks no longer expect or require a rigid structure (e.g. ## Procedure section is no longer needed)
💬 Devin is a better communicator! When Devin makes notable deviations from the initial plan, it will inform you more reliably.
🔢 Devin is less reliant on playbooks and can follow ad-hoc plans more effectively
Add secrets to library mid-session
Convenience improvement for secrets management:
General UI Improvements
We’ve done some cleanup to our mobile UI, settings page, and session controls.
Devin is now faster!
You’ll notice that Devin has a faster time to the first message, and is quicker at completing some actions. Expect more improvements in the coming days!
Devin’s Work Log
Devin now maintains a work log in its planner. More quickly grok what Devin’s accomplished with the work log!
Open the accordions to read Devin’s retro of its work at each step. 🟢/ 🟠 / 🔴 correspond to A/B/C grades. You’ll also find timestamps and how long Devin spent at each step.
Devin Mobile Improvements
Try Devin while on the go - Devin mobile is now more usable, although we have a couple other improvements in the works!
Slack Integration 2.0
Create sessions directly from Slack, attach Playbooks and Snapshots using Slack’s convenient modal interface!
Look for the “Create a new session” option in the message menu (you may need to click “More message shortcuts” the first time you try this)
Also try the /devin shortcut or open Slack’s shortcut launcher
Use “send to channel” to mirror sessions started via the web app on Slack
This enables anyone in the channel (with Devin access) to quickly follow along and collaborate with Devin!
Seamless communication across Slack channels and web app
Messages sent via the web app are now mirrored in Slack threads and vice versa
Turn on Slack notifications mid-session
Slack notifications are now more informative, containing message contents and session title.
June 30, 2024
Use Devin’s Editor and Shell
It can sometimes be more convenient to directly take actions for Devin, rather than providing instructions for Devin to follow.
We’re excited to share that you can now directly use Devin’s machine. The new “Use Devin’s Machine” button in the web interface opens VSCode in a new tab. Using VSCode, you can directly read and edit Devin’s files, as well as open up a terminal in Devin’s machine.
Rollback
You can now restore live sessions to a previous state. Rewind Devin’s memory and file system to any past moment in time and resume - useful for undoing wrong decisions, exploring alternative solutions, quickly iterating on playbooks/prompts, etc.
Restoring a checkpoint returns Devin to a previous point in time — Devin’s files and memory will be rolled back. This is particularly useful…
- When Devin made good progress, but then makes a mistake — it can often be faster to revert Devin’s changes and let Devin retry with hints (or take over and complete the task yourself by using Devin’s machine), rather than working on top of Devin’s mistakes
- When iterating on a playbook or prompt — try editing a playbook, and rolling back afterwards to quickly test whether the edit enables Devin to succeed reliably
Live Playbook Editing
You can now edit playbooks while you’re running a session! If Devin isn’t responding to the playbook instructions as desired, you can rollback to a previous state in the session, edit the step in the playbook you want to make clearer for Devin, and retry the individual step, instead of rerunning the whole playbook in a new session.
This will allow you to test and iterate to make the playbook more reliable, much faster!
Playbook Editing
Quickly edit a playbook before sending it to Devin. Selected playbooks show up inside of the input box and the input box can be expanded, enabling fast and convenient edits to a Playbook before sending it to Devin.
Inline and in-session playbook edits won’t be reflected in the Playbook Library unless you click the “Update Playbook in library” button. Alternatively, save your edits as new Playbook with the “Create new Playbook in library” button.
Forbidden Actions Reliability
Devin now abides by forbidden actions more reliably when it’s told what not to do via user messages or Playbooks.
Playbooks Library & Past Runs
Explore how your teammates are using Playbooks in the new “Past runs” tab, and directly select Playbooks from library
Ask Devin about Devin
Devin is now aware of its own product features and improvements! Try asking Devin what it knows about the Devin web app, and it’ll explain its features and where to find them.
Start Duplicate Sessions
Quickly kick off 2+ similar sessions with the new “Start duplicate session” button in the sidebar. You’ll be redirected to the Devin home page with your initial message pre-populated along with any attachments, playbooks, and snapshots.
We recommend kicking off 2+ Devin sessions for some tasks, to give Devin more chances to succeed!
Home Screen Upgrades & Shortcuts
The new Devin home screen makes it faster to explore and select Playbooks and Snapshots. We also introduced Shortcuts. Select a snapshot and/or playbook and save them as a shortcut so that they’re quick to reuse!
PR Metrics Dashboard
The PR metrics view aggregates all PRs made by Devin. The PR metrics view is available at https://preview.devin.ai/metrics!
Session Filtering
Quickly filter all of your sessions by creator, status, playbook, date, etc.
May 29, 2024
Playbooks Library
You can now easily create, view and use playbooks by going to the Devin app > Library > Playbooks. You’ll be able to create playbooks for your personal use cases, and explore playbooks from the community. Any playbooks you create will be shared with your team.
You can click in any of your Team or Community Playbooks to see example runs as inspiration for how to use a given playbook.
Playbook Compiler
With the playbook compiler, you can now quickly iterate on your playbook to make sure the format, structure and content are optimized for the best playbook session results.
💡 Tip:
- Write your playbook in the Content on the left hand side
- Click compile and review the newly formatted Playbook
- You can always edit and update the compiled Playbook. When it’s ready, click create!
Interactive Browser
Interactive Browser allows users to directly use Devin’s browser. This feature is especially helpful for browser tasks where Devin may require assistance, such as completing CAPTCHAs, multifactor authentication steps and more.
Knowledge
Knowledge is a collection of tips, instructions, and organizational context for Devin. You can continually add to Devin’s bank of knowledge over time, and Devin will automatically recall relevant knowledge as necessary.
You can easily add knowledge to Devin’s “knowledge bank”, or disable it if needed. View when and how Devin is using Knowledge in any run’s progress updates.
View Code Updates
During a session, you can now click into Devin’s progress updates to view specific code edits Devin made while working through the sub-tasks. You can also view these directly from the Editor.
Progress Updates View
Editor Updates View
Code updates will open a modal where you can track new code written by Devin up to that specific point in time in the session.
View Shell Updates
During a session, you can now click into Devin’s progress updates to view specific shell commands Devin used while working through the sub-tasks. You can also view the Command History from the Shell.
Progress View Shell Updates
Shell Command History
Shell updates will show you the full Command History and related outputs. You can easily copy a command and output by clicking on the three-dots icon.
Any commands that are italicized are commands run at a future point in time in the session, you can jump to different points in time in the session by clicking on different commands in the Command History section.
May 13, 2024
Machine Snapshot Startup Commands
For a given machine snapshot, you can now set a list of startup commands that will be run at the beginning of every run. Some details:
- The commands are run from
~ - The commands run in sequence (so having
cd dirand thenlswill dolsfromdir) - Each command is given a 2 minute timeout (so you can’t run long-running servers with these commands)
Learn more about Machine Snapshots here: Machine Snapshots Guide
Command History
With command history, you can easily see a list of all the commands that Devin ran, along with a preview of their outputs.
💡 Tip:
- Click on a command to jump to the timestamp where Devin used the command.
- Click the menu icon (appears when you hover over a command) to copy the full output.
Keep Alive
Deprecation Warning: This is no longer a supported feature. Devin can be woken up again any time after going to sleep now. It is recommended that hosted services be deployed elsewhere with Devin’s help.
Keep Alive will keep a session alive indefinitely, and will count against Technical Preview users’ daily quota. Manually terminating a session will override Keep Alive.
Note that Keep Alive is useful for keeping any hosted services (devinapps.com links) alive, but is not necessary if Devin helps you deploy apps using third party services like Netlify, Firebase, Vercel, etc.
Browser Notifications
Get notified when Devin sends you a message. You can find this under Settings > Profile.
Pause Devin
The new pause button is a shortcut and alternative to telling Devin to pause.
Open VS Code: Access Devin’s machine
Open VS Code lets you read and edit files on Devin’s machine just like if you were working with Devin in VSCode. You can also open up a terminal in Devin’s machine, which means you have full access to Devin’s machine.
💡 Tip: Combine VSCode with our Machine Snapshots feature to set up everything Devin needs to be productive moving forward:
- Tell Devin “Run
pwdand then pause. Do not do anything else.” - Open VSCode and open up a terminal once Devin is paused
- Do any machine setup yourself (install packages, configure repos, etc.)
- Create a snapshot. Moving forward start sessions with this snapshot - all your future Devins will benefit from the setup you prepared!
Learn more here: Interacting with Devin’s Machine
Cookies + Persisted Secrets
With Persisted Secrets, any secrets that you add in the Settings page will be usable by Devin in all future Devin sessions.
Additionally, with site cookies, Devin will find that it’s already logged in to sites you provide valid cookies for (no login required by Devin!).
- Note that this is a beta feature and may not work for some sites, but we’ve found that it works for Amazon and Resy, and are excited to explore together what else this enables!
- Additionally, Devin may still ask for credentials. You’ll need to remind Devin to first check using its browser whether it’s already logged in!
Learn more here: Persisted Secrets + Site Cookies
[Organizations] Unlist Sessions
This feature is only available to Organizations, not Technical Preview or Personal accounts
My default, all new sessions are visible to your Team (aka Organization). To make a session private to you, click the menu icon (which appears on hover) next to your session name in the sidebar to find the Unlist session option.
[Organizations] Slack Integration
This feature is only available to Organizations, not Technical Preview or Personal accounts
Once you’ve connected Slack to your organization, you’ll be able to initialize Devin directly just by tagging @Devin in Slack. Devin responds in-thread with updates and questions, just as in the regular chat interface.
You can also enable Slack notifications for specific runs and Devin will privately message you whenever there’s a status update. To do so, simply click the Slack icon at the top of any run you’d like to be notified for.
💡 Tip: Use these inline Slack commands to manage your Devin session:
- “mute” → prevents Devin from sending further Slack messages.
- “unmute” → reverses the above.
- “(aside)” or “!aside” → causes Devin to ignore the message (useful for commenting on Devin’s run in-thread).
- “EXIT” → ends the session.
- snapshot:[snapshot-name] → Use a particular snapshot with your run
- playbook:[playbook-name] → Use a particular playbook with your run
