- Miscellaneous bug fixes.
**Upgrade instructions**
N.1.9.3.0 comes with the prebuilt binaries for the Linux and Darwin x86_64 platforms.
Download the corresponding archive and unpack it:
```
tar -xzf arweave-1.9.3.0.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:
```
git fetch --all --tags && git checkout -f N.1.9.3.0
```
You can now run the miner using the arweave-server script.
