Special Notes

End of Life (EOL) Notice
Please note that v2.1.x are the last releases to contain 2acoin-service. Releases after v2.1.x will no longer contain the 2acoin-service binaries and the code will be removed. The next release will not contain 2acoin-service or any legacy WalletGreen dependencies. If you have not converted your wallet(s) and or services over to Proton, zedwallet, or wallet-api you are encouraged to do so soon. The next release will remove all legacy support for older wallets and the daemon API will be changed thus rendering 2acoin-service inoperable. Should you experience any issues working with wallet-api, please make sure that you open an issue so that the issue may be resolved as quickly as possible.

This also establishes the timeline for the End of Support (EOS) of 2acoin-service being the next release (v3.0.0). With the release of v3.0.0, 2acoin-service will no longer be supported or work with the core software.This release includes the replacement for legacy zedwallet. Legacy zedwallet has been replaced with zedwallet++ and all legacy zedwallet code has been removed. Please make sure that you have backed up your keys from legacy wallets, then upgrade them to the new format by using zedwallet, wallet-api, or wallet-upgrader in this release and ensure that you can access your wallets using the above tools.

Clarification: 2acoin-service is not being deprecated as part of this process. It will still be available until further notice specifically regarding that binary.

End of Support (EOS) Notice
Support will be provided for legacy zedwallet through October 31, 2020. After that date, legacy zedwallet will no longer be supported.

Full Node Resync May Be Required
The new version of 2acoin-service will require a full re-sync. If you are using 2acoin-service you will be required to re-sync your node or create a new wallet for v2.1.3.

Release v2.1.2 contained a host of updates to the way that we handle data for fee per byte processing. The updates are necessary for the proper operation of 2ACoind, zedwallet, 2acoin-service, and wallet-api; however, this update may require you to re-sync your wallet with an updated daemon. Please be sure to backup your wallets before update.

If you encounter a message stating that your local blockchain cache is corrupted, please try the directions given (be patient, it may take a while). Or, you may resync your node from scratch.

To help speed up your sync, you may use checkpoints to help speed things up. (Review the steps on how to sync quickly below)
