Dataflow now supports speculative execution for batch pipelines
Dataflow now supports speculative execution for batch pipelines. This feature mitigates the impact of slow-running tasks ( stragglers ) by launching a redundant execution of these tasks. The first task to finish is used, and the other is canceled, which can improve the overall completion time of your pipeline. This feature is generally available.
What's new in Sigma
Admin Add a key file for Snowflake key pair connections When configuring a Snowflake connection, you can add a PKCS#8-formatted key file ( .p8 ) instead of pasting your private key when setting up key pair authentication for the connection or an OAuth service account. For more details, see Connect to Snowflake .
Containers - New CPU Pricing for Containers and Sandboxes
Containers and Sandboxes pricing for CPU time is now based on active usage only, instead of provisioned resources. This means that you now pay less for Containers and Sandboxes. An Example Before and After Imagine running the standard-2 instance type for one hour, which can use up to 1 vCPU, but on average you use only 20% of your CPU capacity.
Notifications, Conductor Queue
This week is all about staying ahead of issues: Notifications graduate from Priority Boarding to General Availability, giving everyone a real-time view of what’s happening across projects and environments. There’s also a new way for our community Conductors to triage questions faster.
Projects deployed using a zip file via API now support branch deploys
When you deploy a project using a ZIP file and the Netlify API, you can now also create branch deploys using the new branch parameter. While it was always possible to pass a branch parameter to the https://api.netlify.com/api/v1/sites/{site_id}/builds endpoint, it previously had no effect for deploys made programmatically using the API.

Modal 1.2.3
- CPU Functions can now be configured to run on non-preemptible capacity by setting nonpreemptible=True in the @app.function() or @app.cls() decorator. This feature is not currently available when requesting a GPU. Note that non-preemptibility incurs a 3x multiplier on CPU and memory pricing. See the Guide for more information on preemptions.
Modal 1.2.2
- modal.Image.run_commands now supports modal.Volume mounts. This can be helpful for accelerating builds by keeping a package manager cache on the Volume: python cache_vol = modal.Volume.from_name("cache-mount") cmd_using_cache = "..." image = modal.Image.debian_slim().run_commands(cmd_using_cache, volumes={"/cache": cache_vol}) All Modal objects now accept...
Modal 1.2.5
- It is now possible to set a custom name= for a Function without using serialized=True. This can be useful when decorating a function multiple times, e.g. applying multiple Modal configurations to the same implementation. It is now possible to start modal shell with a Modal Image ID (modal shell im-abc123).
Modal 1.2.6
- Fixed bug where iterating on a modal.Sandbox.exec output stream could raise unauthenticated errors.
Modal 1.3.0
Modal now supports Python 3.14. Python 3.14t (the free-threading build) support is currently a work in progress, because we are waiting for dependencies to be updated with free-threaded support. Additionally, Modal no longer supports Python 3.9, which has reached end-of-life.
Modal 1.2.1
- It's now possible to override the default -dev suffix applied to the autogenerated URLs for ephemeral Apps (i.e., when using modal serve) via a new dev_suffix field in the .modal.toml config file, or equivalently with the MODAL_DEV_SUFFIX environment variable.
Modal 1.2.0
In this release, we're introducing the concept of "App tags", which are simple key-value metadata that can be included to provide additional organizational context.
Modal 1.3.1
- We've improved our experimental support for Python 3.14t (free-threaded Python) inside Modal containers. The container environment will now use the Python implementation of the Protobuf runtime rather than the incompatible upb implementation.
