Wrangler - 3.69.1

Tue, 06 Aug 2024 08:00:00 EST

#6432 cba2e25 Thanks @petebacondarwin! - fix: prevent crash when running wrangler dev due to missing dependency

Wrangler - 3.69.0

Tue, 06 Aug 2024 08:00:00 EST

#6392 c3e19b7 Thanks @taylorlee! - feat: log Worker startup time in the version upload command
#6370 8a3c6c0 Thanks @CarmenPopoviciu! - feat: Create very basic Asset Server Worker and plumb it into wrangler dev

These changes do the ground work needed in order to add Assets support for Workers in wrangler dev. They implement the following:
- it creates a new package called workers-shared that hosts the Asset Server Worker, and the Router Workerin the future
- it scaffolds the Asset Server Worker in some very basic form, with basic configuration. Further behaviour implementation will follow in a subsequent PR
- it does the ground work of plumbing ASW into Miniflare
#6392 c3e19b7 Thanks @taylorlee! - fix: remove bundle size warning from Worker deploy commands

Bundle size was a proxy for startup time. Now that we have startup time reported, focus on bundle size is less relevant.

Wrangler - 3.68.0

Thu, 01 Aug 2024 08:00:00 EST

#6318 dc576c8 Thanks @danlapid! - feat: Add a log for worker startup time in wrangler deploy
#6097 64f34e8 Thanks @RamIdeas! - feat: implements the --experimental-dev-env (shorthand: --x-dev-env) flag for wrangler pages dev
#6379 31aa15c Thanks @RamIdeas! - fix: clearer error message when trying to use Workers Sites or Legacy Assets with wrangler versions upload
#6367 7588800 Thanks @RamIdeas! - fix: implicitly cleanup (call stop()) in unstable_dev if the returned Promise rejected and the stop() function was not returned
#6330 cfbdede Thanks @RamIdeas! - fix: when the worker’s request.url is overridden using the host or localUpstream, ensure port is overridden/cleared too

When using --localUpstream=example.com, the request.url would incorrectly be “example.com:8787” but is now “example.com”.

This only applies to wrangler dev --x-dev-env and unstable_dev({ experimental: { devEnv: true } }).
#6365 13549c3 Thanks @WalshyDev! - fix: WASM modules meant that wrangler versions secret ... could not properly update the version. This has now been fixed.

D1 - Fixed bug in TypeScript typings for run() API

Fri, 26 Jul 2024 08:00:00 EST

The run() method as part of the D1 Client API had an incorrect (outdated) type definition, which has now been addressed as of @cloudflare/workers-types version 4.20240725.0.

The correct type definition is stmt.run(): D1Result, as run() returns the result rows of the query. The previously incorrect type definition was stmt.run(): D1Response, which only returns query metadata and no results.

Wrangler - 3.67.1

Fri, 26 Jul 2024 08:00:00 EST

#6312 67c611a Thanks @emily-shen! - feat: add CLI flag and config key for experimental Workers + Assets

This change adds a new experimental CLI flag (--experimental-assets) and configuration key (experimental_assets) for the new Workers + Assets work.

The new flag and configuration key are for the time being “inactive”, in the sense that no behaviour is attached to them yet. This will follow up in future work.

Wrangler - 3.67.0

Thu, 25 Jul 2024 08:00:00 EST

#4545 e5afae0 Thanks @G4brym! - Remove experimental/beta constellation commands and binding, please migrate to Workers AI, learn more here https://developers.cloudflare.com/workers-ai/. This is not deemed a major version bump for Wrangler since these commands were never generally available.
#6322 373248e Thanks @IRCody! - Add cloudchamber scope to existing scopes instead of replacing them.

When using any cloudchamber command the cloudchamber scope will now be added to the existing scopes instead of replacing them.
#6276 a432a13 Thanks @CarmenPopoviciu! - feat: Add support for wrangler.jsonc

This commit adds support for wrangler.jsonc config file for Workers. This feature is available behind the --experimental-json-config flag (just like wrangler.json).

To use the new configuration file, add a wrangler.jsonc file to your Worker project and run wrangler dev --experimental-json-config or wrangler deploy --experimental-json-config.

Please note that this work does NOT add wrangler.json or wrangler.jsonc support for Pages projects!
#6168 1ee41ff Thanks @IRCody! - feature: Add list and remove subcommands to cloudchamber registries command.
#6331 e6ada07 Thanks @threepointone! - fix: only warn about miniflare feature support (ai, vectorize, cron) once

We have some warnings in local mode dev when trying to use ai bindings / vectorize / cron, but they are printed every time the worker is started. This PR changes the warning to only be printed once per worker start.

Zero Trust WARP Client - WARP client for macOS (version 2024.6.416.0)

Fri, 28 Jun 2024 08:00:00 EST

A new GA release for the macOS WARP client is now available in the App Center. This release includes some exciting new features. It also includes additional fixes and minor improvements.

New features:

Admins can now elect to have ZT WARP clients connect using the MASQUE protocol; this setting is in Device Profiles. Note: before MASQUE can be used, the global setting for Override local interface IP must be enabled. For more detail, refer to Device tunnel protocol. This feature will be rolled out to customers in stages over approximately the next month.
The Device Posture client certificate check has been substantially enhanced. The primary enhancement is the ability to check for client certificates that have unique common names, made unique by the inclusion of the device serial number or host name (for example, CN = 123456.mycompany, where 123456 is the device serial number).

Additional changes and improvements:

Fixed a known issue where the certificate was not always properly left behind in /Library/Application Support/Cloudflare/installed_cert.pem.
Fixed an issue where re-auth notifications were not cleared from the UI when the user switched configurations.
Fixed a macOS firewall rule that allowed all UDP traffic to go outside the tunnel. Relates to TunnelVision ( CVE-2024-3661).
Fixed an issue that could cause the Cloudflare WARP menu bar application to disappear when switching configurations.

Warning:

This is the last GA release that will be supporting older, deprecated warp-cli commands. There are two methods to identify these commands. One, when used in this release, the command will work but will also return a deprecation warning. And two, the deprecated commands do not appear in the output of warp-cli -h.

Known issues:

If a user has an MDM file configured to support multiple profiles (for the switch configurations feature), and then changes to an MDM file configured for a single profile, the WARP client may not connect. The workaround is to use the warp-cli registration delete command to clear the registration, and then re-register the client.
There are certain known limitations preventing the use of the MASQUE tunnel protocol in certain scenarios. Do not use the MASQUE tunnel protocol if:
- A Magic WAN integration is on the account and does not have the latest packet flow path for WARP traffic. Please check migration status with your account team.
- Your account has Regional Services enabled.

Zero Trust WARP Client - WARP client for Windows (version 2024.6.415.0)

Fri, 28 Jun 2024 08:00:00 EST

A new GA release for the macOS WARP client is now available in the App Center. This release includes some exciting new features. It also includes additional fixes and minor improvements.

New features:

Admins can now elect to have ZT WARP clients connect using the MASQUE protocol; this setting is in Device Profiles. Note: before MASQUE can be used, the global setting for Override local interface IP must be enabled. For more detail, refer to Device tunnel protocol. This feature will be rolled out to customers in stages over approximately the next month.
The ZT WARP client on Windows devices can now connect before the user completes their Windows login. This Windows pre-login capability allows for connecting to on-premise Active Directory and/or similar resources necessary to complete the Windows login.
The Device Posture client certificate check has been substantially enhanced. The primary enhancement is the ability to check for client certificates that have unique common names, made unique by the inclusion of the device serial number or host name (for example, CN = 123456.mycompany, where 123456 is the device serial number).

Additional changes and improvements:

Added a new Unable to Connect message to the UI to help in troubleshooting.
The upgrade window now uses international date formats.
Made a change to ensure DEX tests are not running when the tunnel is not up due to the device going to or waking from sleep. This is specific to devices using the S3 power model.
Fixed a known issue where the certificate was not always properly left behind in %ProgramData%\Cloudflare\installed_cert.pem.
Fixed an issue where ICMPv6 Neighbor Solicitation messages were being incorrectly sent on the WARP tunnel.
Fixed an issue where a silent upgrade was causing certain files to be deleted if the target upgrade version is the same as the current version.

Warning:

This is the last GA release that will be supporting older, deprecated warp-cli commands. There are two methods to identify these commands. One, when used in this release, the command will work but will also return a deprecation warning. And two, the deprecated commands do not appear in the output of warp-cli -h.

Known issues:

If a user has an MDM file configured to support multiple profiles (for the switch configurations feature), and then changes to an MDM file configured for a single profile, the WARP client may not connect. The workaround is to use the warp-cli registration delete command to clear the registration, and then re-register the client.
There are certain known limitations preventing the use of the MASQUE tunnel protocol in certain scenarios. Do not use the MASQUE tunnel protocol if:
- A Magic WAN integration is on the account and does not have the latest packet flow path for WARP traffic. Please check migration status with your account team.
- Your account has Regional Services enabled.

Wed, 22 May 2024 08:00:00 EST

A new beta release for the Windows WARP client is now available in the App Center.

Notable updates:

Added a new Unable to Connect message to the UI to help in troubleshooting.
In the upgrade window, a change was made to use international date formats to resolve an issue with localization.
Made a change to ensure DEX tests are not running when the tunnel is not up due to the device going to or waking from sleep. This is specific to devices using the S3 power model.
Fixed a known issue where the certificate was not always properly left behind in %ProgramData%\Cloudflare\installed_cert.pem.
Fixed an issue where ICMPv6 Neighbor Solicitation messages were being incorrectly sent on the WARP tunnel.

Known issues:

If a user has an MDM file configured to support multiple profiles (for the switch configurations feature), and then changes to an MDM file configured for a single profile, the WARP client may not connect. The workaround is to use the warp-cli registration delete command to clear the registration, and then re-register the client.

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

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.

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

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.

Trace - Cloudflare Trace now supports BYOIP zones

Mon, 18 Mar 2024 08:00:00 EST

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.

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.

D1 - Legacy alpha automated backups disabled

Mon, 18 Dec 2023 08:00:00 EST

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.

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

Tue, 08 Aug 2023 08:00:00 EST

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

Fri, 09 Jun 2023 08:00:00 EST

AbortSignal.any() is now available.
Updated V8 to 11.4.
Following an update to the WHATWG URL spec, the delete() and has() methods of the URLSearchParams class now accept an optional second argument to specify the search parameter’s value. This is potentially a breaking change, so it is gated behind the new urlsearchparams_delete_has_value_arg and url_standard compatibility flags.
Added the strict_compression_checks compatibility flag for additional DecompressionStream error checking.

Read more about the experimental back end in the announcement blog.

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

Builds which fail due to Out of memory (OOM) will return a proper error message indicating so rather than Internal error.

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.

With this change, Stream responds to the upload request with an error, allowing you to give users immediate feedback if they attempt to upload non-video content.

Pages - API messaging update

Thu, 15 Dec 2022 08:00:00 EST

Updated all API messaging to be more helpful.

Queues - sendBatch support

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 multiple 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.
