UOX3 0.99.4: Encryption-less clients from v4.0.0p - v7.0.110.39*, though some lower/higher client versions might also work.
But which client-version should I pick?
Depends on what you're after. Every new expansion bring with it a host of new items and monsters you can make use of, even if you want to disable certain features such as the detailed tooltips, sixth character slot, Necromancers, Paladins, Ninja, Samurai and Elves - and (in theory) general client-side bugfixes. As such, there should (in theory, again) be few drawbacks from using the highest client-version that is compatible with UOX3, unless compatibility for that client-version was added very recently and thus might contain unsupported features not handled correctly by UOX3. See feature-negotiation section further down in this post for information on how to enable/disable specific client-features.
From version 7.0.24.2 of the classic client, the format for various data-files (maps, statics, items, etc) changed, resulting in the loss of compatibility with old tools like InsideUO, WorldForge, etc. UOFiddler has been updated to support these new formats, however, and can convert files forth and back between UOP and MUL formats. Clients from 7.0.25.7 to 7.0.86.2+ are usable with UOX3 as long as UOX3 has access to classic/non-UOP versions of the map-files from those clients. This means those map-files have to be converted from UOP to classic mul format, for instance using a tool like UOFiddler.
UOX3 can read maps in the UOP format since 0.99.3! No need to convert!
Where can I get hold of a client that is compatible with UOX3?

About client encryption removal
Only clients with the encryption removed can connect to UOX3 shards. The most common option to achieve this is to use ClassicUO - an open source UO client with a host of improvements over the original client (though it still relies on the original client's data files). Alternatively, you can use software like Razor Enhanced to remove encryption from the original client in runtime (memory only). Another option is Razor, but the latest versions of this are no longer compatible with the original UO client.
About UOX3 and keeping up with the client-updates
Over the years there have been an ungodly amount of versions and expansions released for the UO-client, and keeping UOX3 working with every new version released, through packet-changes and encryption-changes, has always been an unrelenting rat-race at best, with the compatibility with clients coming and going for variable periods of time, depending on the extensiveness of client-changes and the amount of developers and third-party tool-makers around to add additional support for those changes. Whether or not UOX3 is kept up to date with client-updates depends entirely on volunteer efforts. Contributions are more than welcome!
Feature-negotiation between UOX3 and UO clients
Plenty of "feature improvements" have been added since the original UO version was released, though not everyone are equally happy with all of those additions. Fortunately, the client has been designed in a way that many of the "feature improvements" can be switched on/off from the server-side! What follows here is a list of all such feature-improvements that can be enabled or disabled for clients connecting to an UOX3 server:

History and details for UO client versions
This list was partly grabbed from nerun's post on the RunUO forums, with some modifications based on other sources. Accuracy may vary for people depending on release-regions and such, I guess.
