I would like to enquire the product end of life for the different versions for CipherSafe.NET.
Version 1.6.1 (released in March 2014) is the active one. All versions prior to 1.6.1 can be considered EOLed. Version 1.5.5 (released in July 2010) can be still used for .NET 2.x-based apps, but it has a couple of minor bugs with the documented workarounds (so no updates will be done to v.1.5.5). Does this make sense?
