Overview

This release brings significant UX and performance improvements to data onboarding, provisioning, and retrieval systems.

New configuration options let you customize the shape of UnixFS DAGs generated during the data import, control the scope of DAGs announced on the Amino DHT, select which delegated routing endpoints are queried, and choose whether to enable HTTP retrieval alongside Bitswap over Libp2p.

🔦 Highlights

Opt-in HTTP Retrieval client

This release adds experimental support for retrieving blocks directly over HTTPS (HTTP/2), complementing the existing Bitswap over Libp2p.

The opt-in client enables Kubo to use delegated routing results with /tls/http multiaddrs, connecting to HTTPS servers that support Trustless HTTP Gateway's Block Responses (?format=raw, application/vnd.ipld.raw). Fetching blocks via HTTPS (HTTP/2) simplifies infrastructure and reduces costs for storage providers by leveraging HTTP caching and CDNs.

To enable this feature for testing and feedback, set:

$ ipfs config --json HTTPRetrieval.Enabled true

See HTTPRetrieval for more details.

Dedicated Reprovider.Strategy for MFS

The Mutable File System (MFS) in Kubo is a UnixFS filesystem managed with ipfs files commands. It supports familiar file operations like cp and mv within a folder-tree structure, automatically updating a MerkleDAG and a "root CID" that reflects the current MFS state. Files in MFS are protected from garbage collection, offering a simpler alternative to ipfs pin. This makes it a popular choice for tools like IPFS Desktop and the WebUI.

Previously, the pinned reprovider strategy required manual pin management: each dataset update meant pinning the new version and unpinning the old one. Now, new strategies—mfs and pinned+mfs—let users limit announcements to data explicitly placed in MFS. This simplifies updating datasets and announcing only the latest version to the Amino DHT.

Users relying on the pinned strategy can switch to pinned+mfs and use MFS alone to manage updates and announcements, eliminating the need for manual pinning and unpinning. We hope this makes it easier to publish just the data that matters to you.

See Reprovider.Strategy for more details.

Experimental support for MFS as a FUSE mount point

The MFS root (filesystem behind the ipfs files API) is now available as a read/write FUSE mount point at Mounts.MFS. This filesystem is mounted in the same way as Mounts.IPFS and Mounts.IPNS when running ipfs mount or ipfs daemon --mount.

Note that the operations supported by the MFS FUSE mountpoint are limited, since MFS doesn't store file attributes.

See Mounts and docs/fuse.md for more details.

Grid view in WebUI

The WebUI, accessible at http://127.0.0.1:5001/webui/, now includes support for the grid view on the Files screen:

Enhanced DAG-Shaping Controls

This release advances CIDv1 support by introducing fine-grained control over UnixFS DAG shaping during data ingestion with the ipfs add command.

Wider DAG trees (more links per node, higher fanout, larger thresholds) are beneficial for large files and directories with many files, reducing tree depth and lookup latency in high-latency networks, but they increase node size, straining memory and CPU on resource-constrained devices. Narrower trees (lower link count, lower fanout, smaller thresholds) are preferable for smaller directories, frequent updates, or low-power clients, minimizing overhead and ensuring compatibility, though they may increase traversal steps for very large datasets.

Kubo now allows users to act on these tradeoffs and customize the width of the DAG created by ipfs add command.

New DAG-Shaping ipfs add Options

Three new options allow you to override default settings for specific import operations:

• --max-file-links: Sets the maximum number of child links for a single file chunk.
• --max-directory-links: Defines the maximum number of child entries in a "basic" (single-chunk) directory.
  • Note: Directories exceeding this limit or the Import.UnixFSHAMTDirectorySizeThreshold are converted to HAMT-based (sharded across multiple blocks) structures.
• --max-hamt-fanout: Specifies the maximum number of child nodes for HAMT internal structures.

Persistent DAG-Shaping Import.* Configuration

You can set default values for these options using the following configuration settings:

• Import.UnixFSFileMaxLinks
• Import.UnixFSDirectoryMaxLinks
• Import.UnixFSHAMTDirectoryMaxFanout
• Import.UnixFSHAMTDirectorySizeThreshold

Updated DAG-Shaping Import Profiles

The release updated configuration profiles to incorporate these new Import.* settings:

• Updated Profile: test-cid-v1 now includes current defaults as explicit Import.UnixFSFileMaxLinks=174, Import.UnixFSDirectoryMaxLinks=0, Import.UnixFSHAMTDirectoryMaxFanout=256 and Import.UnixFSHAMTDirectorySizeThreshold=256KiB
• New Profile: test-cid-v1-wide adopts experimental directory DAG-shaping defaults, increasing the maximum file DAG width from 174 to 1024, HAMT fanout from 256 to 1024, and raising the HAMT directory sharding threshold from 256KiB to 1MiB, aligning with 1MiB file chunks.
  • Feedback: Try it out and share your thoughts at discuss.ipfs.tech/t/should-we-profile-cids or ipfs/specs#499.

Datastore Metrics Now Opt-In

To reduce overhead in the default configuration, datastore metrics are no longer enabled by default when initializing a Kubo repository with ipfs init.
Metrics prefixed with <dsname>_datastore (e.g., flatfs_datastore_..., leveldb_datastore_...) are not exposed unless explicitly enabled. For a complete list of affected default metrics, refer to prometheus_metrics_added_by_measure_profile.

🔦 Highlights

AutoTLS now enabled by default for nodes with 1 hour uptime

Starting now, any publicly dialable Kubo node with a /tcp listener that remains online for at least one hour will receive a TLS certificate through the AutoTLS feature.
This occurs automatically, with no need for manual setup.

To bypass the 1-hour delay and enable AutoTLS immediately, users can explicitly opt-in by running the following commands:

$ ipfs config --json AutoTLS.Enabled true
$ ipfs config --json AutoTLS.RegistrationDelay 0

AutoTLS will remain disabled under the following conditions:

• The node already has a manually configured /ws (WebSocket) listener
• A private network is in use with a swarm.key
• TCP or WebSocket transports are disabled, or there is no /tcp listener

To troubleshoot, use GOLOG_LOG_LEVEL="error,autotls=info.

For more details, check out the AutoTLS configuration documentation or dive deeper with AutoTLS libp2p blog post.

New WebUI features

The WebUI, accessible at http://127.0.0.1:5001/webui/, now includes support for CAR file import and QR code sharing directly from the Files view. Additionally, the Peers screen has been updated with the latest ipfs-geoip dataset.

RPC and CLI command changes

• ipfs config is now validating json fields (#10679).
• Deprecated the bitswap reprovide command. Make sure to switch to modern routing reprovide. (#10677)
• The stats reprovide command now shows additional stats for Routing.AcceleratedDHTClient, indicating the last and next reprovide times. (#10677)
• ipfs files cp now performs basic codec check and will error when source is not a valid UnixFS (only dag-pb and raw codecs are allowed in MFS)

Bitswap improvements from Boxo

This release includes performance and reliability improvements and fixes for minor resource leaks. One of the performance changes greatly improves the bitswap clients ability to operate under high load, that could previously result in an out of memory condition.

IPNS publishing TTL change

Many complaints about IPNS being slow are tied to the default --ttl in ipfs name publish, which was set to 1 hour. To address this, we’ve lowered the default IPNS Record TTL during publishing to 5 minutes, matching similar TTL defaults in DNS. This update is now part of boxo/ipfs (GO, boxo#859) and @helia/ipns (JS, helia#749).

IPFS_LOG_LEVEL deprecated

The variable has been deprecated. Please use GOLOG_LOG_LEVEL instead for configuring logging levels.

Pebble datastore format update

If the pebble database format is not explicitly set in the config, then automatically upgrade it to the latest format version supported by the release ob pebble used by kubo. This will ensure that the database format is sufficiently up-to-date to be compatible with a major version upgrade of pebble. This is necessary before upgrading to use pebble v2.

Badger datastore update

An update was made to the badger v1 datastore that avoids use of mmap in 32-bit environments, which has been seen to cause issues on some platforms. Please be aware that this could lead to a performance regression for users of badger in a 32-bit environment. Badger users are advised to move to the flatds or pebble datastore.

Datastore Implementation Updates

The go-ds-xxx datastore implementations have been updated to support the updated go-datastore v0.8.2 query API. This update removes the datastore implementations' dependency on goprocess and updates the query API.

One Multi-error Package

Kubo previously depended on multiple multi-error packages, github.com/hashicorp/go-multierror and go.uber.org/multierr. These have nearly identical functionality so there was no need to use both. Therefore, go.uber.org/multierr was selected as the package to depend on. Any future code needing multi-error functionality should use go.uber.org/multierr to avoid introducing unneeded dependencies.

Fix hanging pinset operations during reprovides

The reprovide process can be quite slow. In default settings, the reprovide process will start reading CIDs that belong to the pinset. During this operation, starvation can occur for other operations that need pinset access (see #10596).

We have now switch to buffering pinset-related cids that are going to be reprovided in memory, so that we can free pinset mutexes as soon as possible so that pinset-writes and subsequent read operations can proceed. The downside is larger pinsets will need some extra memory, with an estimation of ~1GiB of RAM memory-use per 20 million items to be reprovided.

Use Reprovider.Strategy to balance announcement prioritization, speed, and memory utilization.

🔦 Highlights

Bitswap improvements from Boxo

This release includes boxo/bitswap performance and reliability improvements and fixes for minor resource leaks. One of the performance changes greatly improves the bitswap clients ability to operate under high load, that could previously result in an out of memory condition.

Improved IPNS interop

Improved compatibility with third-party IPNS publishers by restoring support for compact binary CIDs in the Value field of IPNS Records (IPNS Specs). As long the signature is valid, Kubo will now resolve such records (likely created by non-Kubo nodes) and convert raw CIDs into valid /ipfs/cid content paths.
Note: This only adds support for resolving externally created records—Kubo’s IPNS record creation remains unchanged. IPNS records with empty Value fields default to zero-length /ipfs/bafkqaaa to maintain backward compatibility with code expecting a valid content path.
