KatKoyn Core 2.4

What's new in 2.4

This is the first release with new KatKoyn branding. All functionality is identical to the previous Nyancoin release.
All previous Nyancoin keys, wallets, blockchain data and everything else is the same.

Filename Changes
Due to filename changes, this is NOT a direct drop-in replacement for v2.3
The previous wallet file, configuration file and blockchain files can be used.
However some changes will be required:
- Executables have been renamed, nyancoind -> katkoynd, nyancoin-qt.exe -> katkoyn-qt.exe and other equivalents.
- The config file has changed from nyancoin.conf to katkoyn.conf
- The default data directory is now .katkoyn on linux based systems, or similar to ...AppData\Roaming\KatKoyn on Windows and others.

Suggested upgrade process
- Download the new version, or compile from source if required.
- Stop the old version and wait for it to exit completely.
- Make at least one backup of wallet.dat, preferably multiple copies to an external storage device (You should be doing this regularly anyway)
- Remove the old executable, and replace with the new. Old ones are named nyancoin*, new are katkoyn*
- Rename the configuration file from nyancoin.conf to katkoyn.conf
- Rename the folder / directory that contains the data files. Anything previously named 'nyancoin' is now 'katkoyn'
- Alternatively if using command line options to set a custom data directory, this can be kept as-is, or you can rename the location and amend the command line to match.
- Start the executable. If you have previously used command line options, these will still be valid.
If these filename and location changes are not made, the software will run as for a new installation, and all previously used files will be ignored including the wallet. If this happens, you have NOT lost anything - it's just that the wallet and other files are not recognised. Stopping, renaming and starting again will fix that problem.

New installations

• Download the new version, or compile from source if required.
• For GUI desktop versions, copy the executable to a suitable location.
• For katkoynd command line versions, it is recommended to run the executable under its own user, with the files in a directory for that user.
• Start the executable, the default data location will be used.
• Alternatively a custom location can be set using command line options.
• Wait while the blockchain is downloaded - this will take several hours or more depending on system capabilities. …
