N.2.0.0.2

The release includes a bugfix, a major performance optimization, and a script for removing old wallet lists.

A performance optimization

After the 2.0 upgrade, some nodes were noticed to spend significant amount of time decoding recall data encoded in Base64URL and consequently lag behind.

The release introduces a new Base64URL decoding library, which is more than 20x faster than the previous one.

A script for removing old wallet lists

Starting from the version 2.0, the wallet lists are no longer required for block syncing and recall block verification. Therefore, the node will not download them again after removal. This allows to clean up a lot of disk space.

A syncing bugfix

A bug is fixed which prevented the v2 transaction data from syncing in a timely manner. The tooling for posting v2 transactions has not been published yet, so the bug had a mild effect on the network.

Upgrade instructions

N.2.0.0.2 comes with the prebuilt binaries for the Linux and Darwin x86_64 platforms.

Download the corresponding archive and unpack it:

tar -xzf arweave-2.0.0.2.linux-x86_64.tar.gz

It makes sense to unpack it inside a dedicated directory. You can always move this directory around, but the miner may not work if you move only some of the files. The weave data would, by default, be stored in this directory, too, but it can be overridden using the data_dir command-line argument.
The archive contents look like this:

bin/  data/  erts-10.3/  lib/  releases/

To run the miner, execute ./bin/start <arguments>. See the mining guide for more details.
If your OS/platform architecture is not in the list, check README for how to build the miner from sources.

If you want to run the miner from the existing Git folder, execute the following command to upgrade (note the submodule update and the cleaning step):

git fetch --all --tags && git checkout -f N.2.0.0.2

You can now run the miner using the arweave-server script.
