 - Starting from this release, the SplitStore feature is automatically activated on new nodes. However, for existing Lotus users, you need to explicitly configure SplitStore by uncommenting the `EnableSplitstore` option in your `config.toml` file. To enable SplitStore, set `EnableSplitstore=true`, and to disable it, set `EnableSplitstore=false`. **It's important to note that your Lotus node will not start unless this configuration is properly set. Set it to false if you are running a full archival node!**
 - This feature release requires a **minimum Go version of v1.19.7 or higher to successfully build Lotus**. Additionally, Go version v1.20 and higher is now also supported.
 - **Storage Providers:** The proofs libraries now have CUDA enabled by default, which requires you to install (CUDA)[https://lotus.filecoin.io/tutorials/lotus-miner/cuda/] if you haven't already done so. If you prefer to use OpenCL on your GPUs instead, you can use the `FFI_USE_OPENCL=1` flag when building from source. On the other hand, if you want to disable GPUs altogether, you can use the `FFI_NO_GPU=1` environment variable when building from source.

+- **Syncing issues:** If you have been struggling with syncing issues in normal operations you can try to adjust the amount of threads used for more concurrent FMV execution through via the `LOTUS_FVM_CONCURRENCY` enviroment variable. It is set to 4 threads by default. Recommended formula for concurrency == YOUR_RAM/4 , but max is 128.

 The SplitStore also has two new commands:
 
-- `lotus chain prune hot` will run an online (badger vlog) garbage collection on the hotstore.
-- `lotus chain prune hot-moving` will run an moving garbage collection the hotstore
+- `lotus chain prune hot` is a much less resource-intensive GC and is best suited for situations where you don't have the spare disk space for a full GC.
+- `lotus chain prune hot-moving` will run a full moving garbage collection of the hotstore. This commands create a new hotstore before deleting the old one so you need working room in the hotstore directory. The current size of a fully GC'd hotstore is around 295 GiB so you need to make sure you have at least that available.

+You can read more about the new SplitStore commands in [the documentation](https://lotus.filecoin.io/lotus/configure/splitstore/#manual-chain-store-garbage-collection).
