Release 2.6.9

The release introduces a few improvements and bug fixes.

• Improve syncing speed and stability significantly;
• fix the issue where the node connected to a VDF server would occasionally lag behind;
• add support for the VDF server pull interface, removing the requirement of a static IP when using a VDF server; to enable it, run your client with enable vdf_server_pull;
• improve the mining performance of the nodes connected to the VDF server;
• fix the bug introduced in 2.6.4 where two-chunk solutions with the chunks coming from different partitions would be dropped;
• disable the server-side packing/unpacking of chunks by default (used to be enabled but very strictly limited); enable with enable pack_served_chunks;
• add the GET /inflation/{height} endpoint returning the inflation reward for the given height;
• reduce peak memory footprint during node initialization, and baseline memory footprint while syncing.

Note if you are running your own VDF servers, update the server nodes first, then the client nodes.

The release comes with the prebuilt binaries for the Linux x86_64 platforms.

Release 2.6.8

This release introduces a patch that adds to the transition period before the activation of Arweave 2.6’s trustless price oracle, in order to give miners additional time to on-board packed data to the network. The release delays the onset of the transition window by 4 months, and extends the interpolation between of old and new pricing systems to 18 months, from 12. This release introduces a hard fork that activates at height 1,189,560, approximately 2023-05-30 16:00 UTC.

Please note that the activation date for this patch is May 30th, as the present version has a real but small effect on end-user storage pricing. You will need to make sure you have upgraded your miner before this time to connect to the network.

Release 2.6.7.1

• Fix a regression introduced by 2.6.7 where packed chunks were not padded correctly;
• tweak the data discovery and syncing a bit.

The release comes with the prebuilt binaries for the Linux x86_64 platforms.

If you want to run the miner from the existing Git folder, execute the following command:

git fetch --all --tags && git checkout -f N.2.6.7.1

Release 2.6.7

• Reduce the overhead caused by the inefficient GET /recent_hash_list_diff handler,
  essentially speeding up (re-)packing;
• fix the bug introduced in 2.6.6 where the in-place repacking could store invalid data;
  clean up the invalid records;
• fixed the bug where the node would print the out-of-sync warning in the
  console when only one (or several out of many) trusted peer(s) are lagging behind.

The release comes with the prebuilt binaries for the Linux x86_64 platforms.

If you want to run the miner from the existing Git folder, execute the following command:

git fetch --all --tags && git checkout -f N.2.6.7

Release 2.6.6

The release introduces a few improvements and bug fixes.

• Fix the regression introduced in 2.6.5 where data synchronisation became very slow;
• speed up the in-place repacking of the 2.5 storage;
• choose the default packing rate based on the actual packing latency achieved by the node's processor;
• hard-code the trusted peers to use when no trusted peers are specified explicitly; filter out the peers which fell behind.

The release comes with the prebuilt binaries for the Linux x86_64 platforms.

If you want to run the miner from the existing Git folder, execute the following command:

git fetch --all --tags && git checkout -f N.2.6.6

Release 2.6.5

The release introduces various improvements and bug fixes.

Some hightlights:

• Fix a bug where the node would fail to produce a block if it cannot find the recent VDF checkpoints in the cache;
• improve the node behaviour under disk space constraints:
  • stop writing data to storage modules residing on the separate drives when less than 1% of the disk space remains available;
  • stop writing data to storage modules on the data_dir drive when the remaining space is less than what is reserved for the disk pool and block headers cache;
• fix a bug introduced in 2.6.4 where the node may fail to join the network when only some of the specified trusted peers are not available;
• add support for syncing exclusively from local peers:
  • to enable the feature, specify local peers to sync from using the local_peer command line parameter and set the sync_from_local_peers_only command line flag;
  • the peer address may be (although it does not have to be) a private IP address;
  • make sure to specify local_peer on both sides - the node does not expect to be rate limited when syncing from a "local" peer so its peer needs to recognize it as local too;
• the data synchronization is improved;
• the sync_jobs configuration parameter now determines the number of workers responsible for fetching the chunks from the network and also from the other local storage modules:
  • if you run the node with sync_jobs 0, it won't sync any data from the network and it won't copy and repack the data between storage modules either;
  • if you set a positive value, the node will at first copy and repack the data across the intersecting storage modules and only then attempt to sync the missing data from the network;
  • if you want to copy and repack local storage modules but do not want to sync from the network, start the node with sync_from_local_peers_only (you do not have to specify local_peers).

The release comes with the prebuilt binaries for the Linux x86_64 platforms.

If you want to run the miner from the existing Git folder, execute the following command:

git fetch --all --tags && git checkout -f N.2.6.5

Release 2.6.4

The release introduces various improvements and bug fixes.

Some hightlights:

• Added GET /wallet/[addr]/reserved_rewards_total serving the sum (in Winston) of the reserved mining rewards;
• introduced support for repairing specific RocksDB databases; specify each database to repair with:

repair_rocksdb [file]

• VDF peers addressed using domain names now stay connected even if the IP addresses change (applies to both clients and servers configured via vdf_client_peer and vdf_server_trusted_peer accordingly);
• sped up loading of blocks and transactions when joining the network;
• a bug is fixed where mining with custom size storage modules would sometimes fail with "mined_block_but_failed_to_read_chunk_proofs";
• fixed a bug where a failure to allocate a large page would result in the obscure "rwlock destroy" error.

The release comes with the prebuilt binaries for the Linux x86_64 platforms.

Release 2.6.2

The release introduces various improvements and bug fixes.

Some hightlights:

• The memory consumption issues of 2.6.1 are fixed;
• the v2_index_data_size_by_packing metric is recorded with the new "partition_size" and "partition_index" labels;
• the node may now pack and update in place the unpacked data in the 2.5 storage (activate by enable legacy_storage_unpacked_packing);
• the default packing rate is now chosen based on the CPU core count, albeit conservatively;
• the mempool processing is improved by filtering out unfitting transactions early in the process.

The release comes with the prebuilt binaries for the Linux x86_64 platforms.

If you want to run the miner from the existing Git folder, upgrade Erlang to version 24 and execute the following command:

Release 2.6.1

The release introduces a convenient way to copy and repack data across the local storage modules, including the legacy 2.5 storage.

Some hightlights:

• the data is copied and repacked from the 2.5 storage to the corresponding storage modules, if any, and between the storage modules; once finished, the node attempts to sync the missing data from the network;
• additionally, the 2.5 data is repacked in place when the node is launched with enable legacy_storage_repacking;
• the broken chunk index records are repaired in the process;
• the limits for the number of chunks to keep in RAM (by the syncing, packing, and mining processes accordingly) are chosen based on the available memory and reported on startup; the limits may be overriden via data_cache_size_limit [number], packing_cache_size_limit [number], and mining_server_chunk_cache_size_limit [number];
• the estimated maximum packing rate is reported on startup (you might want to restart the node with packing_rate [number] afterwards.

The release comes with the prebuilt binaries for the Linux x86_64 platforms. arweave-2.6.1.linux-x86_64.tar.gz works on Ubuntu 21+ and CentOS 8. To run on Ubuntu 18 or 20, grab arweave-2.6.1.ubuntu18-x86_64.tar.gz or arweave-2.6.1.ubuntu20-x86_64.tar.gz . CentOS 7 is not supported.
