Note for Synology users:
If you're having trouble using the compiled 0.5.2 binary it may be an issue with the GNU libc version on Synology. Please try [release 0.4.25](https://github.com/Pectojin/duplicati-client/releases/tag/0.4.25_beta) in that case. https://github.com/Pectojin/duplicati-client/releases/tag/0.4.25_beta
