The Bee team is elated to announce the v2.5.0 release! 🎉

Our focus this time around is on improvements to uploads and downloads. We've made several optimizations to the pusher, pushsync protocol, and peer routing.

The release also includes various bug fixes and API related changes, so make sure to check out the full list below.

For questions, comments, and feedback, reach out on Discord.

See the pre-release blog post here.

Features

• Added a new profiling tool method under /debug/fgprof that profiles both CPU and I/O operations ( #4984 ).

Bug fixes

• Fixed an issue with the chunk streams API where the tag stats were not being updated ( #4920 ).
• Fixed a stewardship iterator bug with respect to file references uploaded using the /bytes endpoint and erasure coding ( #4955 #4996 ).
• Fixed a bug where in rare circumstances the uint64 chunk cache size would underflow ( #4986 ).
• Fixed a tag related bug where if a tag associated with an active upload were to be deleted, the syncing of chunks would get stuck ( #4995 #5018 #5019 #5032 ).
• Fixed an ACT upload bug for the /chunks and /soc endpoints ( #5008 ).

Optimizations

• Various improvements in pusher and pushsync protocols ( #4958 ).
  • The pusher now only checks if a chunk's batch exists, and does not do a full verification of the stamp before pushing the chunk to the network.
  • Forwarder nodes in a pushsync request no longer perform receipt validation for shallow receipts.
  • Origin nodes allow for some tolerance for shallow receipts by a factor of the maximum allowed reserve doubling.
  • Max parallel workers count in the pusher has been raised to 128.
  • Closest peer selection used by pushsync and retrieval protocols now processes fewer peers by ignoring peers whose proximity order is beyond the proximity of the chunk and the pusher node's address.

API Changes

• Added OpenAPI Content-Type field to HEAD /bytes endpoint ( #4915 ).
• GET /pins now returns empty array instead of null ( #4971 ).
• Removed the /stake/migrate obsolete endpoint from the OpenAPI specs ( #4945 ).
• Changed the OpenAPI default value of the deferred uploads header to true ( #4956 ).
• Fixed an issue where Access-Control-Expose-Headers were not being formatted and set correctly ( #4960 ).
• Fixed OpenAPI specs for the /status/neighborhoods and /status/peers endpoints ( #4972 ).
• Added a new field chain_address to the /addresses endpoint, which will replace the now deprecated ethereum field in a future release ( #4978 ).
• Fixed the OpenAPI response type for PATCH /tags/{uid} ( #4979 ).
• Added the SwarmActTimestampHeader, SwarmActPublisherHeader, SwarmActHistoryAddressHeader as CORS headers for ACT related uploads and added SwarmActHistoryAddressHeader to the AccessControlExposeHeaders for ACT related uploads/downloads ( #5008 #5024 ).

Hardening

• Changed the default Testnet blocktime to 12 seconds ( #4969 ).
• Set sane defaults to several config options like bootnode address and blockchain block time ( #4998 ).

This release is dedicated to the memory of ldeffenb, who recently passed away.

ldeffenb was an irreplaceable pillar of the Swarm community—undoubtedly the most active, knowledgeable, kind, dedicated, and selfless individual among us. He touched lives throughout the community, always offering invaluable help and support. In addition to personally assisting community members, he made countless contributions to testing new candidate Bee versions, playing a critical role in identifying and resolving important issues. His efforts were always entirely altruistic, driven by a genuine desire to help others and improve Swarm to fulfill the project's vision.

His sudden passing is a tremendous loss to us all, and his absence is deeply felt across the entire community. Outside Swarm, ldeffenb was also an active participant in other non-commercial community projects, where he held a similarly vital role.

In his honor, Bee v2.4.0 will include a new line in the startup message logs: "Share the knowledge." This simple yet profound message was ldeffenb's personal slogan, encapsulating his spirit and values, which he consistently demonstrated through his actions.

Bug fixes

• Fixed a bug where pushsync requests would get stuck due to connectivity problems with the storer neighborhood nodes ( #4950).

For a full PR rundown, please consult the v2.4.0 diff.

This is patch release that fixes a bug where ultra-light nodes where unable to start due to some chequebook related rule changes during initialization (#4938).

This is patch release that fixes a bug where feeds uploaded prior to v2.3.0 were not retrievable from nodes running the latest release (#4929).

v2.3.0

The Bee team is pleased to announce the v2.3.0 release. 🎉

Reserve Doubling for Optimized Node Rewards

The most anticipated feature of this release is the new ability for node operators to double the reserve capacity of their nodes to store chunks from a “sister” neighborhood. By storing chunks from its sister neighborhood, a node gains the opportunity to participate in the redistribution game whenever its sister neighborhood is selected, doubling its chances of participating in the redistribution game. The amount of doubling is controlled by a new config option, reserve-capacity-doubling which by default is 0 and is currently capped at 1.

See the Official Release Announcement for more details.

Graffiti Several Owner Chunks

GSOC features allows for uploads of multiple version of the same Single-Owner-Chunk but different payloads to be picked up by a subscriber in a distant neighborhood. The SOC addresses can be configured to target a specific neighborhood to trigger the message subscriptions of the listeners. A WebSocket connection can be registered for a particular SOC address using the new /gsoc/subscribe/{address} endpoint to pick up the new payloads of the SOC in real time.

For questions, comments, and feedback, reach out on Discord.

Features

• Allow user to specify the retrieval redundancy level in the download headers ( #4814 ).
• Reserve size doubling allows for doubling of the reserve capacity to be able to participate in multiple sister neighborhoods. ( #4847 )
  • Added a new status endpoint path, status/neighborhoods that returns the different neighborhoods the nodes is storing chunks for in string binary form, the proximity to the neighborhood, and the respective reserves sizes for each neighborhood ( #4853 ).
  • Added committed depth field to the status response. The committed depth is the current storage radius + reserve doubling amount ( #4892 ).
• Graffiti Several Owner Chunks feature adds the ability to upload multiple versions of the Single-Owner-Chunk (SOC) to a specific neighborhood where owners of the neighbor nodes can subscribe to pick up latest versions of the same SOC in real time ( #4901 ).

Bug fixes

• Fixed a bug where block-chain transaction would get stuck in pending status mode due to faulty nonce calculation ( #4839 #4867 ).
• Fixed a bug where a node is unable to block-list peers if connected peers are all from inbound connections ( #4871 ).
• Several boot-node related fixes ( #4909 #4910 )
• The storage incentives agent can no longer attempt to participate in a round before the global warm up period is over ( #4898 ).

Optimization

• Improved reserve sampling duration by avoiding certain unnecessary crypto operations for SOCs and matching the worker count to the available number of CPUs ( #4882 ).

Hardening

• Readiness endpoint now returns a JSON response based on the initialization status of the node ( #4601 ).
• Reduced verbosity of some logs in kademlia and transaction packages from Info to Debug ( #4825 ).
• Wallet endpoint can now be called even if swap is not enabled ( #4859 ).
• RCHash endpoint now returns the total duration in seconds ( #4862 ).
