D1 - HTTP API now returns a HTTP 400 error for invalid queries

Fri, 12 Apr 2024 08:00:00 EST

Previously, D1’s HTTP API returned a HTTP 500 Internal Server error for an invalid query. An invalid SQL query now correctly returns a HTTP 400 Bad Request error.

D1’s Workers API is unaffected by this change.

Workers - 2024-04-11

Thu, 11 Apr 2024 08:00:00 EST

Improve Streams API spec compliance by exposing desiredSize and other properties on stream class prototypes
The new URL.parse(...) method is implemented. This provides an alternative to the URL constructor that does not throw exceptions on invalid URLs.
R2 bindings objects now have a storageClass option. This can be set on object upload to specify the R2 storage class - Standard or Infrequent Access. The property is also returned with object metadata.

Workers AI - Add AI native binding

Thu, 11 Apr 2024 08:00:00 EST

Added new AI native binding, you can now run models with const resp = await env.AI.run(modelName, inputs)
Deprecated @cloudflare/ai npm package. While existing solutions using the @cloudflare/ai package will continue to work, no new Workers AI features will be supported. Moving to native AI bindings is highly recommended

Wrangler - 3.50.0

Thu, 11 Apr 2024 08:00:00 EST

#5587 d95450f Thanks @CarmenPopoviciu! - fix: pages functions build-env should throw error if invalid Pages config file is found
#5572 65aa21c Thanks @CarmenPopoviciu! - fix: fix pages function build-env to exit with code rather than throw fatal error

Currently pages functions build-env throws a fatal error if a config file does not exit, or if it is invalid. This causes issues for the CI system. We should instead exit with a specific code, if any of those situations arises.
#5291 ce00a44 Thanks @pmiguel! - feature: Added bespoke OAuth scope for Queues management.

D1 - D1 alpha databases will stop accepting live SQL queries on July 1, 2024

Fri, 05 Apr 2024 08:00:00 EST

Now that D1 is generally available and production ready, alpha D1 databases are deprecated and need to be migrated by July 1, 2024 to accept new queries.

Refer to alpha database migration guide to migrate to the new, generally available, database architecture.

Workers - 2024-04-05

Fri, 05 Apr 2024 08:00:00 EST

A new JavaScript-native remote procedure call (RPC) API is now available, allowing you to communicate more easily across Workers and between Workers and Durable Objects.

Wrangler - 3.48.0

Fri, 05 Apr 2024 08:00:00 EST

#5429 c5561b7 Thanks @ocsfrank! - R2 will introduce storage classes soon. Wrangler allows you to interact with storage classes once it is enabled on your account.

Wrangler supports an -s flag that allows the user to specify a storage class when creating a bucket, changing the default storage class of a bucket, and uploading an object.
#5531 887150a Thanks @penalosa! - fix: Write wrangler pages functions build-env to file rather than stdout

Wrangler - 3.46.0

Thu, 04 Apr 2024 08:00:00 EST

#5282 b7ddde1 Thanks @maxwellpeterson! - feature: Add source map support for Workers

Adds the source_maps boolean config option. When enabled, source maps included in the build output are uploaded alongside the built code modules. Uploaded source maps can then be used to remap stack traces emitted by the Workers runtime.
#5215 cd03d1d Thanks @GregBrimble! - feature: support named entrypoints in service bindings

This change allows service bindings to bind to a named export of another Worker. As an example, consider the following Worker named bound:

Up until now, you could only bind to the default entrypoint. With this change, you can bind to EntrypointA or entrypointB too using the new entrypoint option:

To bind to named entrypoints with wrangler pages dev, use the # character:
#5215 cd03d1d Thanks @GregBrimble! - fix: ensure request url and cf properties preserved across service bindings

Previously, Wrangler could rewrite url and cf properties when sending requests via service bindings or Durable Object stubs. To match production behaviour, this change ensures these properties are preserved.
Updated dependencies [ cd03d1d, 6c3be5b, cd03d1d, cd03d1d]:
- miniflare@3.20240403.0

Durable Objects - Durable Objects support for Oceania region

Wed, 03 Apr 2024 08:00:00 EST

Durable Objects can reside in Oceania, lowering Durable Objects request latency for eyeball Workers in Oceania locations.

Refer to Durable Objects to provide location hints to objects.

Workers - 2024-04-03

Wed, 03 Apr 2024 08:00:00 EST

When the brotli_content_encoding compatibility flag is enabled, the Workers runtime now supports compressing and decompressing request bodies encoded using the Brotli compression algorithm. Refer to this docs section for more detail.

Wrangler - 3.45.0

Wed, 03 Apr 2024 08:00:00 EST

#5377 5d68744 Thanks @CarmenPopoviciu! - feat: Add wrangler.toml support in wrangler pages deploy

As we are adding wrangler.toml support for Pages, we want to ensure that wrangler pages deploy works with a configuration file.
#5471 489b9c5 Thanks @zebp! - feature: Add version-id filter for Worker tailing to filter logs by scriptVersion in a gradual deployment

This allows users to only get logs in a gradual deployment if you are troubleshooting issues specific to one deployment. Example: npx wrangler tail --version-id 72d3f357-4e52-47c5-8805-90be978c403f
#5462 68faf67 Thanks @OilyLime! - revert: Removes support for private networking Hyperdrive configs, pending more work to support the feature. Non-breaking change since the feature wasn’t yet supported.

Tue, 02 Apr 2024 08:00:00 EST

You can now write Workers in Python

D1 - D1 is generally available

Mon, 01 Apr 2024 08:00:00 EST

D1 is now generally available and production ready. Read the blog post for more details on new features in GA and to learn more about the upcoming D1 read replication API.

Developers with a Workers Paid plan now have a 10GB GB per-database limit (up from 2GB), which can be combined with existing limit of 50,000 databases per account.
Developers with a Workers Free plan retain the 500 MB per-database limit and can create up to 10 databases per account.
D1 databases can be exported as a SQL file.

Durable Objects - Billing reduction for WebSocket messages

Mon, 01 Apr 2024 08:00:00 EST

Durable Objects request billing applies a 20:1 ratio for incoming WebSocket messages. For example, 1 million Websocket received messages across connections would be charged as 50,000 Durable Objects requests.

This is a billing-only calculation and does not impact Durable Objects metrics and analytics.

Hyperdrive - Hyperdrive is now Generally Available

Mon, 01 Apr 2024 08:00:00 EST

Hyperdrive is now Generally Available and ready for production applications.

Read the announcement blog to learn more about the Hyperdrive and the roadmap, including upcoming support for MySQL databases.

Workers - 2024-04-01

Mon, 01 Apr 2024 08:00:00 EST

The new unwrap_custom_thenables compatibility flag enables workers to accept custom thenables in internal APIs that expect a promise (for instance, the ctx.waitUntil(...) method).
TransformStreams created with the TransformStream constructor now have a cancel algorithm that is called when the stream is canceled or aborted. This change is part of the implementation of the WHATWG Streams standard.
The nodejs_compat compatibility flag now includes an implementation of the MockTracker API from node:test. This is not an implementation of the full node:test module, and mock timers are currently not included.
Exceptions reported to Tail Workers now include a “stack” property containing the exception’s stack trace, if available.

AI Gateway - 2024-03-26

Tue, 26 Mar 2024 08:00:00 EST

LLM Side Channel vulnerability fixed
Providers: Added Anthropic, Google Vertex, Perplexity as providers.

Queues - Delay messages published to a queue

Tue, 26 Mar 2024 08:00:00 EST

Messages published to a queue and/or marked for retry from a queue consumer can now be explicitly delayed. Delaying messages allows you to defer tasks until later, and/or respond to backpressure when consuming from a queue.

Refer to Batching and Retries to learn how to delay messages written to a queue.

Queues - Support for pull-based consumers

Mon, 25 Mar 2024 08:00:00 EST

Queues now supports pull-based consumers. A pull-based consumer allows you to pull from a queue over HTTP from any environment and/or programming language outside of Cloudflare Workers. A pull-based consumer can be useful when your message consumption rate is limited by upstream infrastructure or long-running tasks.

Review the documentation on pull-based consumers to configure HTTP-based pull.

Turnstile - 2024-03-25

Mon, 25 Mar 2024 08:00:00 EST

Added more supported languages.

Hyperdrive - Improved local development configuration

Tue, 19 Mar 2024 08:00:00 EST

Hyperdrive now supports a WRANGLER_HYPERDRIVE_LOCAL_CONNECTION_STRING_ environmental variable for configuring local development to use a test/non-production database, in addition to the localConnectionString configuration in wrangler.toml.

Refer to Local development for instructions on how to configure Hyperdrive locally.

Queues - Default content type now set to JSON

Mon, 18 Mar 2024 08:00:00 EST

The default content type for messages published to a queue is now json, which improves compatibility with the upcoming pull-based queues.

Any Workers created on or after the compatibility date of 2024-03-18, or that explicitly set the queues_json_messages compatibility flag, will use the new default behaviour. Existing Workers with a compatibility date prior will continue to use v8 as the default content type for published messages.

Tue, 12 Mar 2024 08:00:00 EST

As of wrangler@3.33.0, wrangler d1 execute and wrangler d1 migrations apply now default to using a local database, to match the default behavior of wrangler dev.

It is also now possible to specify one of --local or --remote to explicitly tell wrangler which environment you wish to run your commands against.

Workers - 2024-03-11

Mon, 11 Mar 2024 08:00:00 EST

Built-in APIs that return Promises will now produce stack traces when the Promise rejects. Previously, the rejection error lacked a stack trace.
A new compat flag fetcher_no_get_put_delete removes the get(), put(), and delete() methods on service bindings and Durable Object stubs. This will become the default as of compatibility date 2024-03-26. These methods were designed as simple convenience wrappers around fetch(), but were never documented.
Updated v8 to version 12.3.

D1 - Billing for D1 usage

Tue, 05 Mar 2024 08:00:00 EST

As of 2024-03-05, D1 usage will start to be counted and may incur charges for an account’s future billing cycle.

Developers on the Workers Paid plan with D1 usage beyond included limits will incur charges according to D1’s pricing.

Developers on the Workers Free plan can use up to the included limits. Usage beyond the limits below requires signing up for the $5/month Workers Paid plan.

Account billable metrics are available in the Cloudflare Dashboard and GraphQL API.

Queues - Explicit retries no longer impact consumer concurrency/scaling.

Sat, 24 Feb 2024 08:00:00 EST

Calling retry() or retryAll() on a message or message batch will no longer have an impact on how Queues scales consumer concurrency.

Previously, using explicit retries via retry() or retryAll() would count as an error and could result in Queues scaling down the number of concurrent consumers.

Workers - 2024-02-23

Fri, 23 Feb 2024 08:00:00 EST

Sockets now support an opened attribute.

Thu, 22 Feb 2024 08:00:00 EST

Access for SaaS applications can be setup with OIDC as an authentication method. OIDC and SAML 2.0 are now both fully supported.

Access - WARP as an identity source for Access

Thu, 22 Feb 2024 08:00:00 EST

Allow users to log in to Access applications with their WARP session identity. Users need to reauthenticate based on default session durations. WARP authentication identity must be turned on in your device enrollment permissions and can be enabled on a per application basis.

D1 - API changes to `run()`

Fri, 16 Feb 2024 08:00:00 EST

A previous change (made on 2024-02-13) to the run() query statement method has been reverted.

run() now returns a D1Result, including the result rows, matching its original behaviour prior to the change on 2024-02-13.

Future change to run() to return a D1ExecResult, as originally intended and documented, will be gated behind a compatibility date as to avoid breaking existing Workers relying on the way run() currently works.

Stream - Tonemapping impovements for HDR content

Fri, 16 Feb 2024 08:00:00 EST

In certain cases, videos uploaded with an HDR colorspace (such as footage from certain mobile devices) appeared washed out or desaturated when played back. This issue is resolved for new uploads.

D1 - API changes to `raw()`, `all()` and `run()`

Tue, 13 Feb 2024 08:00:00 EST

D1’s raw(), all() and run() query statement methods have been updated to reflect their intended behaviour and improve compatibility with ORM libraries.

raw() now correctly returns results as an array of arrays, allowing the correct handling of duplicate column names (such as when joining tables), as compared to all(), which is unchanged and returns an array of objects. To include an array of column names in the results when using raw(), use raw({columnNames: true}).

run() no longer incorrectly returns a D1Result and instead returns a D1ExecResult as originally intended and documented.

This may be a breaking change for some applications that expected raw() to return an array of objects.

Refer to D1 client API to review D1’s query methods, return types and TypeScript support in detail.

Databases using D1’s legacy alpha backend will no longer run automated hourly backups. You may still choose to take manual backups of these databases.

The D1 team recommends moving to D1’s new production backend, which will require you to export and import your existing data. D1’s production backend is faster than the original alpha backend. The new backend also supports Time Travel, which allows you to restore your database to any minute in the past 30 days without relying on hourly or manual snapshots.

Vectorize - Metadata API changes

Wed, 08 Nov 2023 08:00:00 EST

Vectorize now supports distinct returnMetadata and returnValues arguments when querying an index, replacing the now-deprecated returnVectors argument. This allows you to return metadata without needing to return the vector values, reducing the amount of unnecessary data returned from a query. Both returnMetadata and returnValues default to false.

For example, to return only the metadata from a query, set returnMetadata: true.

New Workers projects created on or after 2023-11-08 or that update the compatibility date for an existing project will use the new return type.

D1 - Row count now returned per query

Sat, 19 Aug 2023 08:00:00 EST

D1 now returns a count of rows_written and rows_read for every query executed, allowing you to assess the cost of query for both pricing and index optimization purposes.

The meta object returned in D1’s Client API contains a total count of the rows read (rows_read) and rows written (rows_written) by that query. For example, a query that performs a full table scan (for example, SELECT * FROM users) from a table with 5000 rows would return a rows_read value of 5000:

Refer to D1 pricing documentation to understand how reads and writes are measured. D1 remains free to use during the alpha period.

D1 - Bind D1 from the Cloudflare dashboard

Wed, 09 Aug 2023 08:00:00 EST

You can now bind a D1 database to your Workers directly in the Cloudflare dashboard. To bind D1 from the Cloudflare dashboard, select your Worker project -> Settings -> Variables -> and select D1 Database Bindings.

Note: If you have previously deployed a Worker with a D1 database binding with a version of wrangler prior to 3.5.0, you must upgrade to wrangler v3.5.0 first before you can edit your D1 database bindings in the Cloudflare dashboard. New Workers projects do not have this limitation.

Legacy D1 alpha users who had previously prefixed their database binding manually with __D1_BETA__ should remove this as part of this upgrade. Your Worker scripts should call your D1 database via env.BINDING_NAME only. Refer to the latest D1 getting started guide for best practices.

We recommend all D1 alpha users begin using wrangler 3.5.0 (or later) to benefit from improved TypeScript types and future D1 API improvements.

Stream - Scheduled Deletion

D1 - New default storage subsystem

Thu, 27 Jul 2023 08:00:00 EST

Databases created via the Cloudflare dashboard and Wrangler (as of v3.4.0) now use D1’s new storage subsystem by default. The new backend can be 6 - 20x faster than D1’s original alpha backend.

To understand which storage subsystem your database uses, run wrangler d1 info YOUR_DATABASE and inspect the version field in the output.

Databases with version: beta use the new storage backend and support the Time Travel API. Databases with version: alpha only use D1’s older, legacy backend.

D1 - Time Travel

Thu, 27 Jul 2023 08:00:00 EST

Time Travel is now available. Time Travel allows you to restore a D1 database back to any minute within the last 30 days (Workers Paid plan) or 7 days (Workers Free plan), at no additional cost for storage or restore operations.

Refer to the Time Travel documentation to learn how to travel backwards in time.

Databases using D1’s new storage subsystem can use Time Travel. Time Travel replaces the snapshot-based backups used for legacy alpha databases.

Improved S3 compatibility for ListObjectsV1, now nextmarker is only set when truncated is true.
The R2 worker bindings now support parsing conditional headers with multiple etags. These etags can now be strong, weak or a wildcard. Previously the bindings only accepted headers containing a single strong etag.
S3 putObject now supports sha256 and sha1 checksums. These were already supported by the R2 worker bindings.
CopyObject in the S3 compatible api now supports Cloudflare specific headers which allow the copy operation to be conditional on the state of the destination object.

D1 - Deprecating Error.cause

Mon, 12 Jun 2023 08:00:00 EST

As of wrangler v3.1.1 the D1 client API now returns detailed error messages within the top-level Error.message property, and no longer requires developers to inspect the Error.cause.message property.

To facilitate a transition from the previous Error.cause behaviour, detailed error messages will continue to be populated within Error.cause as well as the top-level Error object until approximately July 14th, 2023. Future versions of both wrangler and the D1 client API will no longer populate Error.cause after this date.

Workers - 2023-06-09

D1 - Location hints

Fri, 19 May 2023 08:00:00 EST

You can now provide a location hint when creating a D1 database, which will influence where the leader (writer) is located. By default, D1 will automatically create your database in a location close to where you issued the request to create a database. In most cases this allows D1 to choose the optimal location for your database on your behalf.

Pages - Build error message improvement

Fri, 19 May 2023 08:00:00 EST

DDoS protection - Network-layer DDoS managed ruleset - 2023-04-17

Mon, 17 Apr 2023 08:00:00 EST

Previously, only a subset of rules were exposed publicly. In rare situations, these rules can cause false positives. When this happens, you can customize their behavior using overrides.

Besides these rules, the DDoS managed rules contain other rules that do not cause issues. Until now, these rules were not shown in the dashboard or referenced in the documentation.

Cloudflare now shows all rules in the dashboard, including these high-confidence rules. This means that packets matching these rules will now have the correct rule identifier. The newly published rules are read-only and you cannot disable them.

Turnstile - 2023-04-17

Queues - Consumer concurrency (upcoming)

Wed, 15 Mar 2023 08:00:00 EST

Queue consumers will soon automatically scale up concurrently as a queues’ backlog grows in order to keep overall message processing latency down. Concurrency will be enabled on all existing queues by 2023-03-28.

To opt-out, or to configure a fixed maximum concurrency, set max_concurrency = 1 in your wrangler.toml file or via the queues dashboard.

To opt-in, you do not need to take any action: your consumer will begin to scale out as needed to keep up with your message backlog. It will scale back down as the backlog shrinks, and/or if a consumer starts to generate a higher rate of errors. To learn more about how consumers scale, refer to the consumer concurrency documentation.

Notifications - 2023-03-13

Queues - Explicit acknowledgement (new feature)

Thu, 02 Mar 2023 08:00:00 EST

You can now acknowledge individual messages with a batch by calling .ack() on a message.

This allows you to mark a message as delivered as you process it within a batch, and avoids the entire batch from being redelivered if your consumer throws an error during batch processing. This can be particularly useful when you are calling external APIs, writing messages to a database, or otherwise performing non-idempotent actions on individual messages within a batch.

Queues - Higher per-queue throughput

Wed, 01 Mar 2023 08:00:00 EST

Stream - Earlier detection (and rejection) of non-video uploads

Wed, 04 Jan 2023 08:00:00 EST

Cloudflare Stream now detects non-video content on upload using the POST API and returns a 400 Bad Request HTTP error with code 10059.

Previously, if you or one of your users attempted to upload a file that is not a video (ex: an image), the request to upload would appear successful, but then fail to be encoded later on.

Stream - Deprecating the 'per-video' Analytics API

Mon, 07 Nov 2022 08:00:00 EST

The “per-video” analytics API is being deprecated. If you still use this API, you will need to switch to using the GraphQL Analytics API by February 1, 2023. After this date, the per-video analytics API will be no longer available.

The GraphQL Analytics API provides the same functionality and more, with additional filters and metrics, as well as the ability to fetch data about multiple videos in a single request. Queries are faster, more reliable, and built on a shared analytics system that you can use across many Cloudflare products.

For more about this change and how to migrate existing API queries, refer to this post and the GraphQL Analytics API docs.

Stream - More accurate bandwidth estimates for live video playback

Thu, 20 Oct 2022 08:00:00 EST

When playing live video, Cloudflare Stream now provides significantly more accurate estimates of the bandwidth needs of each quality level to client video players. This ensures that live video plays at the highest quality that viewers have adequate bandwidth to play.

As live video is streamed to Cloudflare, we transcode it to make it available to viewers at mulitple quality levels. During transcoding, we learn about the real bandwidth needs of each segment of video at each quality level, and use this to provide an estimate of the bandwidth requirements of each quality level the in HLS (.m3u8) and DASH (.mpd) manifests.

If a live stream contains content with low visual complexity, like a slideshow presentation, the bandwidth estimates provided in the HLS manifest will be lower, ensuring that the most viewers possible view the highest quality level, since it requires relatively little bandwidth. Conversely, if a live stream contains content with high visual complexity, like live sports with motion and camera panning, the bandwidth estimates provided in the HLS manifest will be higher, ensuring that viewers with inadequate bandwidth switch down to a lower quality level, and their playback does not buffer.

This change is particularly helpful if you’re building a platform or application that allows your end users to create their own live streams, where these end users have their own streaming software and hardware that you can’t control. Because this new functionality adapts based on the live video we receive, rather than just the configuration advertised by the broadcaster, even in cases where your end users’ settings are less than ideal, client video players will not receive excessively high estimates of bandwidth requirements, causing playback quality to decrease unnecessarily. Your end users don’t have to be OBS Studio experts in order to get high quality video playback.

No work is required on your end — this change applies to all live inputs, for all customers of Cloudflare Stream. For more, refer to the docs.
