+## [1.8.0] - 2023-05-04
+### Added
+ - Concurrent plot transfers to both remote and local archive paths. Previously was one plot transferred at a time.
+ - Checking for adequate free space on both tmp and dst paths before starting another plotting job.
+ - Replotting selection (Farming page settings) can now target uncompressed plots for deletion.
+## Changed
+ - Fix for Download button on Settings pages that were providing the wrong config file. Thanks @TuftyBruno.
+ - Updated German and Portugese translations.  Thanks to @slowfinger and @antcasq. All contributions are appreciated.
+ - Follow Chia version numbers (like 1.8.0) from now on, as Machinaris is on their release cadence.
+## Updated 
+ - [Cactus](https://github.com/Cactus-Network/cactus-blockchain/releases/tag/1.7.1) to v1.7.1
+ - [Chia](https://github.com/Chia-Network/chia-blockchain/releases/tag/1.8.0) to v1.8.0
+ - [Gigahorse](https://github.com/madMAx43v3r/chia-gigahorse/releases/tag/v1.7.1.giga10) to v1.7.1.giga10.
+ - [HDDCoin](https://github.com/HDDcoin-Network/hddcoin-blockchain/releases/tag/3.0.0-beta.1) to 3.0.0-beta1 based on Chia 1.7.0.
+ - [MMX](https://github.com/madMAx43v3r/mmx-node/releases/tag/v0.10.2) to (v0.10.2) on `testnet10`. 
+
 ## [0.8.8] - 2023-03-23
 ### Added
  - Support for running a blockchain timelord with environment variable `mode` set to `fullnode,timelord`.
