Releasesby Glyphe2b@2.49.0
Minor Changes f842aa8 : Expose a configurable minimum free-disk target with minFreeDiskMb in JavaScript, min_free_disk_mb in Python, and --min-free-disk-mb in template create . Omission uses the team default, while explicit zero requests no minimum growth. Growth is best effort and never shrinks an existing filesystem.

Configurable retention for system tables is in Beta
Account admins can now set an account-wide retention period from 30 to 3,650 days for supported system tables. See Configure system table data retention .
External secrets in Unity Catalog (Beta)
External secrets connect a Unity Catalog schema to AWS Secrets Manager. The secrets appear in Unity Catalog as read-only securable objects that you govern with Unity Catalog privileges. Databricks reads their values from AWS Secrets Manager on demand. See External secrets in Unity Catalog .
Celigo connector (Beta)
The Celigo connector is now available in Lakeflow Connect in Beta . Workspace admins can control access to this feature from the Previews page. The connector ingests audit log events, such as create, update, and delete operations on resources, from Celigo (integrator.io) into Databricks. Authentication uses a Celigo integrator.io API token.
Anysphere Organization connector (Beta)
The Anysphere Organization connector is now available in Lakeflow Connect in Beta . Workspace admins can control access to this feature from the Previews page. The connector uses the Anysphere (Cursor) Organization Admin API to ingest organization members, groups, and group members into Databricks as daily snapshots.
Anaplan connector (Beta)
The Anaplan connector is now available in Lakeflow Connect in Beta . Workspace admins can control access to this feature from the Previews page. The connector ingests audit trail events and user account records from your Anaplan tenant into Databricks. Authentication uses an Anaplan CA certificate and its paired private key. See Anaplan connector .
Openflow gen 1 deployment creation retired
You can no longer create new first generation (gen 1) Openflow deployments (BYOC or Snowflake). All new deployments are second generation (gen 2), created with CREATE OPENFLOW DEPLOYMENT or the Openflow UI. Existing gen 1 deployments continue to work unchanged, and you can still create new gen 1 runtimes on an existing gen 1 deployment.

e2b@2.50.0
Minor Changes 5b015ad : Removed the V1 template build operations and schemas from the generated API clients. The API no longer serves them (runtime 87968fc1e1fa ); control planes carrying that change answer 410 Gone . Template builds go through the Template SDK.
e2b@2.51.0
Minor Changes 5c0f6eb : Remove SDK-side defaults from API request payloads so the API defaults apply when options are omitted. Sandbox create/fork/connect no longer preset a 5-minute timeout, fork no longer presets count: 1 , create no longer presets allow_internet_access , pause no longer presets keeping memory, and template builds no longer preset...
e2b@2.52.0
Minor Changes 2de0cc3: Cap sandbox fork count at 20. e2b sandbox fork --count, JavaScript Sandbox.fork({ count }), and Python Sandbox.fork(count=...) reject a count outside 1–20 before the API call. Counts from 21 through 100 used to reach the API. Omitting count still leaves the field off the request so the API default applies.
e2b@2.55.0
Minor Changes b52cd30: Add mode: 'full' | 'filesystem' (exported as the SnapshotMode type) to createSnapshot / create_snapshot. With 'filesystem', only the filesystem is persisted: the snapshot is smaller and faster to take, and sandboxes created from it cold-boot (start fresh from disk) instead of restoring memory.
e2b@2.56.0
Minor Changes 6a74c39: Require Node.js 22.19.0 or newer and depend on undici@^8 only (undici 7 is dropped). undici 8 respects the server's HTTP/2 SETTINGS_MAX_CONCURRENT_STREAMS and opens more connections when one is saturated.
e2b@2.58.0
Minor Changes 3c4c7cf: - JS: sandbox.commands.streamInput(pid) / sandbox.pty.streamInput(pid) return a CommandInputHandle that sends ordered stdin/PTY input over one StreamInput RPC. Python async: stream_input(pid) returns an AsyncCommandInputHandle; Python sync: stream_input(pid, data) blocks while it sends an iterable of input.
e2b@2.57.0
Minor Changes a1ad326: Add tls to the egress proxy options as true or { serverName?, caCert? } (server_name/ca_cert in Python); getInfo/get_info reports it without the CA.
e2b@2.59.0
This release adds DNS server configuration options for sandboxes and deprecates specific connection URL environment variables in favor of a unified endpoint.
