bunny.net Release Notes

Seamless Domain Migration now supports HTTP (file-based) validation alongside the existing DNS (TXT record) method for issuing SSL certificates before pointing your domain to bunny.net. Choose DNS if you control your domain’s DNS records, or HTTP if you can place a challenge file on the server your domain currently points to.

S3-Compatible API is now available for all!

We have also added a new S3 Storage Zone region: Sydney (SYD) & Uploadpart now supports Content-MD5 validation.

Support for AVIF, HEIC and HEIF as input formats, and AVIF as an output format, has been promoted to General Availability.

New reference page documenting Bunny DNS default limits, including the maximum number of records per zone (5,000) and DNS zones per account (500). Limits can be raised upon request by contacting sales.

Customize the challenge, block, and rate limit pages shown to visitors when Bunny Shield takes action.

Replace default response pages with fully branded HTML experiences that match your website, including custom styling, messaging, and support information.

Available on Advanced and higher Shield plans.

Added direct play URL and embed URL examples with query parameters, documented the -auto captions flag, and improved cross-linking between Stream pages. Updated MP4 fallback documentation to reflect support for 240p, 360p, 720p & 1080p resolutions.

The Storage Edge API DELETE endpoint now supports deleting the root directory (/ ) of a storage zone. By default, root deletion is blocked as a safety guard. Pass allowRootDelete=true as a query parameter or request header to bypass this protection.

The Bunny CLI now includes full Edge Scripts management (bunny scripts): create, deploy, delete scripts, manage deployments and rollbacks, environment variables and secrets, and custom domains with SSL.

Bunny Optimizer now limits AVIF output to a maximum area of 4 megapixels.

Larger images automatically fall back to another format (WebP, JPEG, or GIF) to keep latency low.

A new 304 processing error code is returned when this limit is reached.

You can now vary cached content based on the value of one or more request headers, such as Accept-Language. Each unique header value combination creates a separate cache entry, enabling localized content, feature flags, and device-specific experiences without sacrificing CDN caching.

WebSocket billing has moved to pay-as-you-go pricing based on connection-minutes, replacing the previous tiered monthly subscription model.

Connection limits can now be configured from 100 to 25,000 concurrent connections per zone.

The Transcribing documentation now includes a complete reference table of all 56 supported languages with their ISO 639-1 codes.

The CDN Logging API now supports exact request ID lookup and includes additional fields such as JA4 TLS client fingerprint, ASN, and ASN organization in the response.

Maximize screen real estate on the bunny player with Compact Controls. Ideal for mobile and embedded players.

You can now enable compact controls on your video library via the Compact Controls toggle within player settings.
