n8n Breaking Changes
This list shows all the versions which include breaking changes and how to upgrade.
1.63.0
What changed?
- The worker server used to bind to IPv6 by default. It now binds to IPv4 by default.
- The worker server's
/healthzused to report healthy status based on database and Redis checks. It now reports healthy status regardless of database and Redis status, and the database and Redis checks are part of/healthz/readiness.
When is action necessary?
- If you experience a port conflict error when starting a worker server using its default port, set a different port for the worker server with
QUEUE_HEALTH_CHECK_PORT. - If you are relying on database and Redis checks for worker health status, switch to checking
/healthz/readinessinstead of/healthz.
1.57.0
What changed?
The verbose log level was merged into the debug log level.
When is action necessary?
If you are setting the env var N8N_LOG_LEVEL=verbose, please update your log level to N8N_LOG_LEVEL=debug.
1.55.0
What changed?
The N8N_BLOCK_FILE_ACCESS_TO_N8N_FILES environment variable now also blocks access to n8n's static cache directory at ~/.cache/n8n/public.
When is action necessary?
If you are writing to or reading from a file at n8n's static cache directory via a node, e.g. Read/Write Files from Disk, please update your node to use a different path.
1.52.0
What changed?
Prometheus metrics enabled via N8N_METRICS_INCLUDE_DEFAULT_METRICS and N8N_METRICS_INCLUDE_API_ENDPOINTS were fixed to include the default n8n_ prefix.
When is action necessary?
If you are using Prometheus metrics from these categories and are using a non-empty prefix, please update those metrics to match their new prefixed names.
1.47.0
What changed?
Calling $(...).last() (or $(...).first() or $(...).all() respectively) without arguments is returning the the last item (or first or all items) of the output that connects the two nodes. Before it was returning the item/items of the first output of that node.
When is action necessary?
If you are using $(...).last() (or $(...).first() or $(...)all() respectively) without arguments for nodes that have multiple outputs (e.g. If, Switch, Compare Datasets, etc.) and you want it to default to the first output. In that case change it to $(...).last(0) (or first or all respectively).
This does not affect the Array functions [].last(), [].first().
1.40.0
What changed?
The default value for the DB_POSTGRESDB_USER environment variable was switched from root to postgres.
When is action necessary?
If your Postgres connection is relying on the old default value root for the DB_POSTGRESDB_USER environment variable, you must now explicitly set DB_POSTGRESDB_USER to root in your environment.
1.37.0
What changed?
The --file flag for the execute CLI command has been removed.
When is action necessary?
If you have scripts relying on the --file flag for the execute CLI command, update them to first import the workflow and then execute it using the --id flag.
1.32.0
What changed?
n8n auth cookie has Secure flag set by default now.
When is action necessary?
If you are running n8n without HTTPS on a domain other than localhost, you need to either setup HTTPS, or you can disable the secure flag by setting the env variable N8N_SECURE_COOKIE to false.
1.27.0
What changed?
The execution mode own was removed.
If EXECUTIONS_PROCESS is set to main or if executions.process in a config file is set to main n8n will print a warning, but start up normally.
If EXECUTIONS_PROCESS is set to own or if executions.process in a config file is set to own n8n will print an error message and refuse to start up.
When is action necessary?
If you use own mode and need the isolation and performance gains, please consider using queue mode instead, otherwise switch to main mode by removing the environment variable or config field.
If you have the environment variable EXECUTIONS_PROCESS or the config field executions.process set, please remove them. The environment variable has no effect anymore and the configuration field will be removed in future releases, prevent n8n from starting if it is still set.
1.25.0
What changed?
If the N8N_ENCRYPTION_KEY environment variable on a main instance does not match the encryptionKey in the config file, the main instance will not initialize. If the N8N_ENCRYPTION_KEY environment variable is missing on a worker, the worker will not initialize.
When is action necessary?
If passing an N8N_ENCRYPTION_KEY environment variable to the main instance, make sure it matches the encryptionKey in the config file. If you are using workers, pass the N8N_ENCRYPTION_KEY environment variable to them.
1.24.0
What changed?
The flag N8N_CACHE_ENABLED was removed. The cache is now always enabled.
Additionally, expressions in credentials now follow the paired item, so if you have multiple input items, n8n will try to pair the matching row to fill in the credential details.
In the Monday.com Node, due to API changes, the data structure of entries in column_values array has changed
When is action necessary?
If you are using the flag N8N_CACHE_ENABLED, remove it from your settings.
In regards to credentials, if you use expression in credentials, you might want to revisit them. Previously, n8n would stick to the first item only, but now it will try to match the proper paired item.
If you are using the Monday.com node and refering to column_values property, check in table below if you are using any of the affected properties of its entries.
| Resource | Operation | Previous | New |
|---|---|---|---|
| Board | Get | owner | owners |
| Board | Get All | owner | owners |
| Board Item | Get | title | column.title |
| Board Item | Get All | title | column.title |
| Board Item | Get By Column Value | title | column.title |
| Board Item | Get | additional_info | column.settings_str |
| Board Item | Get All | additional_info | column.settings_str |
| Board Item | Get By Column Value | additional_info | column.settings_str |
*column.settings_str is not a complete equivalent additional_info
1.22.0
What changed?
Hash algorithm ripemd160 is dropped from .hash() expressions.
sha3 hash algorithm now returns a valid sha3-512 has, unlike the previous implementation that returned a Keccak hash instead.
When is action necessary?
If you are using .hash helpers in expressions with hash algorithm ripemd160, you need to switch to one of the other supported algorithms.
1.15.0
What changed?
Until now, in main mode, n8n used to deregister webhooks at shutdown and reregister them at startup. Queue mode and the flag N8N_SKIP_WEBHOOK_DEREGISTRATION_SHUTDOWN skipped webhook deregistration.
As from now, in both main and queue modes, n8n no longer deregisters webhooks at startup and shutdown, and the flag N8N_SKIP_WEBHOOK_DEREGISTRATION_SHUTDOWN is removed. n8n assumes that third-party services will retry unhandled webhook requests.
When is action necessary?
If using the flag N8N_SKIP_WEBHOOK_DEREGISTRATION_SHUTDOWN, note that it no longer has effect and can be removed from your settings.
1.9.0
What changed?
In nodes, this.helpers.getBinaryStream() is now async.
When is action necessary?
If your node uses this.helpers.getBinaryStream(), add await when calling it.
Example:
const binaryStream = this.helpers.getBinaryStream(id); // until 1.9.0
const binaryStream = await this.helpers.getBinaryStream(id); // since 1.9.0
What changed?
The env vars N8N_BINARY_DATA_TTL and EXECUTIONS_DATA_PRUNE_TIMEOUT no longer have any effect and can be safely removed. Instead of relying on a TTL system for binary data, n8n currently cleans up binary data together with executions during pruning.
When is action necessary?
If using these flags, remove them from your settings and be mindful of the new behavior.
1.6.0
What changed?
The env var N8N_PERSISTED_BINARY_DATA_TTL no longer has any effect and can be removed. This legacy flag was originally introduced to support ephemeral executions (see details), which are no longer supported.
When is action necessary?
If using this flag, remove it from your settings.
1.5.0
What changed?
In the Code node, console.log does not output to stdout by default.
When is action necessary?
If you were relying on console.log for non-manual executions of a Code node, you need to set the env variable CODE_ENABLE_STDOUT to true to send Code node logs to process's stdout.
1.2.0
What changed?
For the Linear node, priority in issue creation is 4 (previously incorrectly 3) for Low.
When is action necessary?
If you were using Low, you were setting a priority of Normal, so please double check you are setting the priority you intend.
1.0.0
What changed?

0.234.0
What changed?
This release introduces two irreversible changes:
- The n8n database will use strings instead of numeric values to identify workflows and credentials
- Execution data is split into a separate database table
When is action necessary?
It will not be possible to read a n8n@0.234.0 database with older versions of n8n, so we recommend that you take a full backup before migrating.
0.232.0

0.135.0
What changed?
The in-node core methods for credentials and binary data have changed.
When is action necessary?
If you are using custom n8n nodes.
How to upgrade:
- The method
this.getCredentials(myNodeCredentials)is now async. Soawaithas to be added in front of it.
Example:
// Before 0.135.0:
const credentials = this.getCredentials(credentialTypeName);
// From 0.135.0:
const credentials = await this.getCredentials(myNodeCredentials);
- Binary data should not get accessed directly anymore, instead the method
await this.helpers.getBinaryDataBuffer(itemIndex, binaryPropertyName)has to be used.
Example:
const items = this.getInputData();
for (const i = 0; i < items.length; i++) {
const item = items[i].binary as IBinaryKeyData;
const binaryPropertyName = this.getNodeParameter('binaryPropertyName', i);
const binaryData = item[binaryPropertyName] as IBinaryData;
// Before 0.135.0:
const binaryDataBuffer = Buffer.from(binaryData.data, BINARY_ENCODING);
// From 0.135.0:
const binaryDataBuffer = await this.helpers.getBinaryDataBuffer(i, binaryPropertyName);
}
0.131.0
What changed?
For the Pipedrive regular node, the deal:create operation now requires an organization ID or person ID, in line with upcoming changes to the Pipedrive API.
When is action necessary?
If you are using the deal:create operation in the Pipedrive regular node, set an organization ID or a person ID.
0.130.0
What changed?
For the Taiga regular and trigger nodes, the server and cloud credentials types are now unified into a single credentials type and the version param has been removed. Also, the issue:create operation now automatically loads the tags as multiOptions.
When is action necessary?
If you are using the Taiga nodes, reconnect the credentials. If you are using tags in the issue:create operation, reselect them.
0.127.0
What changed?
For the Zoho node, the lead:create operation now requires a "Company" parameter, the parameter "Address" is now inside "Additional Options", and the parameters "Title" and "Is Duplicate Record" were removed. Also, the lead:delete operation now returns only the id of the deleted lead.
When is action necessary?
If you are using lead:create with "Company" or "Address", reset the parameters; for the other two parameters, no action needed. If you are using the response from lead:delete, reselect the id key.
0.118.0
What changed?
The minimum Node.js version required for n8n is now v14.
When is action necessary?
If you're using n8n via npm or PM2 or if you're contributing to n8n.
How to upgrade:
Update the Node.js version to v14 or above.
What changed?
In the Postgres, CrateDB, QuestDB and TimescaleDB nodes the Execute Query operation returns the result from all queries executed instead of just one of the results.
When is action necessary?
If you use any of the above mentioned nodes with the Execute Query operation and the result is relevant to you, you are encouraged to revisit your logic. The node output may now contain more information than before. This change was made so that the behavior is more consistent across n8n where input with multiple rows should yield results acccording all input data instead of only one. Please note: n8n was already running multiple queries based on input. Only the output was changed.
0.117.0
What changed?
Removed the "Activation Trigger" node. This node was replaced by two other nodes.
The "Activation Trigger" node was added on version 0.113.0 but was not fully compliant to UX, so we decided to refactor and change it ASAP so it affects the least possible users.
The new nodes are "n8n Trigger" and "Workflow Trigger". Behavior-wise, the nodes do the same, we just split the functionality to make it more intuitive to users.
When is action necessary?
If you use the "Activation Trigger" in any of your workflows, please replace it by the new nodes.
How to upgrade:
Remove the previous node and add the new ones according to your workflows.
Changed the behavior for nodes that use Postgres Wire Protocol: Postgres, QuestDB, CrateDB and TimescaleDB.
All nodes have been standardized and now follow the same patterns. Behavior will be the same for most cases, but new added functionality can now be explored.
You can now also inform how you would like n8n to execute queries. Default mode is Multiple queries which translates to previous behavior, but you can now run them Independently or Transaction. Also, Continue on Fail now plays a major role for the new modes.
The node output for insert operations now rely on the new parameter Return fields, just like update operations did previously.
When is action necessary?
If you rely on the output returned by insert operations for any of the mentioned nodes, we recommend you review your workflows.
By default, all insert operations will have Return fields: * as the default, setting, returning all information inserted.
Previously, the node would return all information it received, without taking into account what actually happened in the database.
0.113.0
What changed?
In the Dropbox node, both credential types (Access Token & OAuth2) have a new parameter called "APP Access Type".
When is action necessary?
If you are using a Dropbox APP with permission type, "App Folder".
How to upgrade:
Open your Dropbox node's credentials and set the "APP Access Type" parameter to "App Folder".
0.111.0
What changed?
In the Dropbox node, now all operations are performed relative to the user's root directory.
When is action necessary?
If you are using any resource/operation with OAuth2 authentication.
If you are using the folder:list operation with the parameter Folder Path empty (root path) and have a Team Space in your Dropbox account.
How to upgrade:
Open the Dropbox node, go to the OAuth2 credential you are using and reconnect it again.
Also, if you are using the folder:list operation, make sure your logic is taking into account the team folders in the response.
0.105.0
What changed?
In the Hubspot Trigger, now multiple events can be provided and the field App ID was so moved to the credentials.
When is action necessary?
If you are using the Hubspot Trigger node.
How to upgrade:
Open the Hubspot Trigger and set the events again. Also open the credentials Hubspot Developer API and set your APP ID.
0.104.0
What changed?
Support for MongoDB as a database for n8n has been dropped as MongoDB had problems saving large amounts of data in a document, among other issues.
When is action necessary?
If you have been using MongoDB as a database for n8n. Please note that this is not related to the MongoDB node.
How to upgrade:
Before upgrading, you can export all your credentials and workflows using the CLI.
n8n export:workflow --backup --output=backups/latest/
n8n export:credentials --backup --output=backups/latest/
You can then change the database to one of the supported databases mentioned here. Finally, you can upgrade n8n and import all your credentials and workflows back into n8n.
n8n import:workflow --separate --input=backups/latest/
n8n import:credentials --separate --input=backups/latest/
0.102.0
What changed?
- The
As Userproperty and theUser Namefield got combined and renamed toSend as User. It also got moved under “Add Options”. - The
Ephemeralproperty got removed. To send an ephemeral message, you have to select the "Post (Ephemeral)" operation.
When is action necessary?
If you are using the following fields or properties in the Slack node:
- As User
- Ephemeral
- User Name
How to upgrade:
Open the Slack node and set them again to the appropriate values.
What changed?
If you have a question in Typeform that uses a previously answered question as part of its text, the question text would look like this in the Typeform Trigger node:
You have chosen {{field:23234242}} as your answer. Is this correct?
Those curly braces broke the expression editor. The change makes it now display like this:
You have chosen [field:23234242] as your answer. Is this correct?
When is action necessary?
If you are using the Typeform Trigger node with questions using the Recall information feature.
How to upgrade:
In workflows using the Typeform Trigger node, nodes that reference such key names (questions that use a previously answered question as part of its text) will need to be updated.
0.95.0
What changed?
In the Harvest Node, we moved the account field from the credentials to the node parameters. This will allow you to work witn multiples accounts without having to create multiples credentials.
When is action necessary?
If you are using the Harvest Node.
How to upgrade:
Open the node set the parameter Account ID.
0.94.0
What changed?
In the Segment Node, we have changed how the properties 'traits' and 'properties' are defined. Now, key/value pairs can be provided, allowing you to send customs traits/properties.
When is action necessary?
When the properties 'traits' or 'properties' are set, and one of the following resources/operations is used:
| Resource | Operation |
|---|---|
| Identify | Create |
| Track | Event |
| Track | Page |
| Group | Add |
How to upgrade:
Open the affected resource/operation and set the parameters 'traits' or 'properties' again.
0.93.0
What changed?
Change in naming of the Authentication field for the Pipedrive Trigger node.
When is action necessary?
If you had set "Basic Auth" for the "Authentication" field in the node.

0.87.0
What changed?
The link.fish node got removed because the service is shutting down.
When is action necessary?
If you are are actively using the link.fish node.
How to upgrade:
Unfortunately, that's not possible. We'd recommend you to look for an alternative service.
0.83.0
What changed?
In the Active Campaign Node, we have changed how the getAll operation works with various resources for the sake of consistency. To achieve this, a new parameter called 'Simple' has been added.
When is action necessary?
When one of the following resources/operations is used:
| Resource | Operation |
|---|---|
| Deal | Get All |
| Connector | Get All |
| E-commerce Order | Get All |

How to upgrade:
Open the affected resource/operation and set the parameter Simple to false.
0.79.0
What changed?
We have renamed the operations in the Todoist Node for consistency with the codebase. We also deleted the close_match and delete_match operations as these can be accomplished using the following operations: getAll, close, and delete.
When is action necessary?
When one of the following operations is used:
- close_by
- close_match
- delete_id
- delete_match
How to upgrade:
After upgrading, open all workflows which contain the Todoist Node. Set the corresponding operation, and then save the workflow.
If the operations close_match or delete_match are used, recreate them using the operations: getAll, delete, and close.
0.69.0
What changed?
We have simplified how attachments are handled by the Twitter node. Rather than clicking on Add Attachments and having to specify the Catergory, you can now add attachments by just clicking on Add Field and selecting Attachments. There's no longer an option to specify the type of attachment you are adding.
When is action necessary?
If you have used the Attachments option in your Twitter nodes.
How to upgrade:
You'll need to re-create the attachments for the Twitter node.
0.68.0
What changed?
To make it easier to use the data which the Slack-Node outputs we no longer return the whole
object the Slack-API returns if the only other property is "ok": true. In this case it returns
now directly the data under "channel".
When is action necessary?
When you currently use the Slack-Node with Operations Channel -> Create and you use any of the data the node outputs.
How to upgrade:
All values that get referenced which were before under the property "channel" are now on the main level. This means that these expressions have to get adjusted.
Meaning if the expression used before was:
{{ $node["Slack"].data["channel"]["id"] }}
it has to get changed to:
{{ $node["Slack"].data["id"] }}
0.67.0
What changed?
The names of the following nodes were not set correctly and got fixed:
- AMQP Sender
- Bitbucket-Trigger
- Coda
- Eventbrite-Trigger
- Flow
- Flow-Trigger
- Gumroad-Trigger
- Jira
- Mailchimp-Trigger
- PayPal Trigger
- Read PDF
- Rocketchat
- Shopify
- Shopify-Trigger
- Stripe-Trigger
- Toggl-Trigger
When is action necessary?
If any of the nodes mentioned above, are used in any of your workflows.
How to upgrade:
For the nodes mentioned above, you'll need to give them access to the credentials again by opening the credentials and moving them from "No Access" to "Access". After you've done that, there are two ways to upgrade the workflows and to make them work in the new version:
Simple
- Note down the settings of the nodes before upgrading
- After upgrading, delete the nodes mentioned above from your workflow, and recreate them
Advanced
After upgrading, select the whole workflow in the editor, copy it, and paste it into a text editor. In the JSON, change the node types manually by replacing the values for "type" as follows:
- "n8n-nodes-base.amqpSender" -> "n8n-nodes-base.amqp"
- "n8n-nodes-base.bitbucket" -> "n8n-nodes-base.bitbucketTrigger"
- "n8n-nodes-base.Coda" -> "n8n-nodes-base.coda"
- "n8n-nodes-base.eventbrite" -> "n8n-nodes-base.eventbriteTrigger"
- "n8n-nodes-base.Flow" -> "n8n-nodes-base.flow"
- "n8n-nodes-base.flow" -> "n8n-nodes-base.flowTrigger"
- "n8n-nodes-base.gumroad" -> "n8n-nodes-base.gumroadTrigger"
- "n8n-nodes-base.Jira Software Cloud" -> "n8n-nodes-base.jira"
- "n8n-nodes-base.Mailchimp" -> "n8n-nodes-base.mailchimpTrigger"
- "n8n-nodes-base.PayPal" -> "n8n-nodes-base.payPalTrigger"
- "n8n-nodes-base.Read PDF" -> "n8n-nodes-base.readPDF"
- "n8n-nodes-base.Rocketchat" -> "n8n-nodes-base.rocketchat"
- "n8n-nodes-base.shopify" -> "n8n-nodes-base.shopifyTrigger"
- "n8n-nodes-base.shopifyNode" -> "n8n-nodes-base.shopify"
- "n8n-nodes-base.stripe" -> "n8n-nodes-base.stripeTrigger"
- "n8n-nodes-base.toggl" -> "n8n-nodes-base.togglTrigger"
Then delete all existing nodes, and then paste the changed JSON directly into n8n. It should then recreate all the nodes and connections again, this time with working nodes.
0.62.0
What changed?
The function "evaluateExpression(...)" got renamed to "$evaluateExpression()" in Function and FunctionItem Nodes to simplify code and to normalize function names.
When is action necessary?
If "evaluateExpression(...)" gets used in any Function or FunctionItem Node.
How to upgrade:
Simply replace the "evaluateExpression(...)" with "$evaluateExpression(...)".
0.52.0
What changed?
To make sure that all nodes work similarly, to allow to easily use the value from other parts of the workflow and to be able to construct the source-date manually in an expression, the node had to be changed. Instead of getting the source-date directly from the flow the value has now to be manually set via an expression.
When is action necessary?
If you currently use "Date & Time"-Nodes.
How to upgrade:
Open the "Date & Time"-Nodes and reference the date that should be converted via an expression. Also, set the "Property Name" to the name of the property the converted date should be set on.
0.37.0
What changed?
To make it possible to support also Rocketchat on-premise the credentials had to be changed.
The subdomain parameter had to get renamed to domain.
When is action necessary?
When you currently use the Rocketchat-Node.
How to upgrade:
Open the Rocketchat credentials and fill the parameter domain. If you had previously the
subdomain "example" set you have to set now "https://example.rocket.chat".
0.19.0
What changed?
The node "Read File From Url" got removed as its functionality got added to "HTTP Request" node where it belongs.
When is action necessary?
If the "Read File From Url" node gets used in any workflow.
How to upgrade:
After upgrading open all workflows which contain a "Read File From Url" node. They will have a "?" as icon as they are not known anymore. Create a new "HTTP Request" node to replace the old one and add the same URL as the previous node had (in case you do not know it anymore you can select the old node, copy it and paste it in a text-editor, it will display all the data the node contained). Then set the "Response Format" to "File". Everything will then function again like before.
What changed?
When "HTTP Request" property "Response Format" was set to "String" it did save the data by default in the property "response". In the new version that can now be configured. The default value got also changed from "response" to "data" to match other nodes with similar functionality.
When is action necessary?
When "HTTP Request" nodes get used which have "Response Format" set to "String".
How to upgrade:
After upgrading open all workflows which contain the concerning Nodes and set "Binary Property" to "response".
0.18.0
What changed?
Because of a typo very often reponse instead of response got used in code. So also on the Webhook-Node. Its parameter reponseMode had to be renamed to correct spelling responseMode.
When is action necessary?
When Webhook-Nodes get used which have "Response Mode" set to "Last Node".
How to upgrade:
After upgrading open all workflows which contain the concerning Webhook-Nodes and set "Response Mode" again manually to "Last Node".
What changed?
Because the CLI library n8n used was not maintained anymore and included packages with security vulnerabilities we had to switch to a different one.
When is action necessary?
When you currently start n8n in your setup directly via its JavaScript file. For example like this:
/usr/local/bin/node ./dist/index.js start
How to upgrade:
Change the path to its new location:
/usr/local/bin/node bin/n8n start
