Our advice is that unless you need one of these fixes go ahead and stay on v1119.
 

Below are the release notes for EntitySpaces 2007.1.1210.0:

• Fixed old style mixed nested AND and OR.
• Fixed Oracle % operator to use MOD() function.
• Fixed Oracle overflow error for some division results, e.g., 1.3333.... with ROUND(expr, 10) (same as STDDEV and VAR).
• Fixed Oracle Paging with Joins.
• Fixed MySQL CONCAT() expression.
• Fixed configless esConfigSettings.ConnectionInfo.Default settor for EntitySpaces.Interfaces.Ce.
• Added new class called esEntityCollectionView. You can create many of these on a single esEntityCollection and sort/filter them all separately. See this blog post for details.
• Updated XML comments in VB and C# entity and collection templates for generated classes.
• Fixed delimiter issue for SqlCe when concatenating (+ operator) string columns with literals.
• Added overload to Like/NotLike operators that takes an ESCAPE character, e.g., where Northwind Products QuantityPerUnit does not have "10%" in it. The "%" needs to be escaped, so it does not behave like a wild card character.
