Having had an off-putting impression because of the spelling mistakes in the announcement of OS5, then again from reading the forums, further reinforced by reading the monthly release notes, I delayed upgrading to OS5 until yesterday.
Thus far, it has gone just fine for me. I have no plans to make the device web-facing - I use a VPN to access my home network - so I have not had the associated issues that have been reported elsewhere, of excessive CPU and disk usage associated with the indexing of content.
The only issue I came across was another spelling error, a typo on the Setup Complete page, on the hyperlink to the Knowledge Base.
