Version 2.5.0

Release date: February 2, 2011

Changes

SphinxQL: The type used for representing signed and unsigned 64bit integers has been changed from SystemInt64 to SystemDecimal. This is to avoid potential integer overflows with very large 64bit document ids. Please note that this is a potentially breaking change, and you should check your code before deploying the new version to production. We're sorry for any inconvience this causes.
This change does not break any calls to the GetXXX methods of the SphinxQLDataReader class except GetValue(), depending on how the result is used.
It may break existing code in case a DataTable is used and column values are casted to their target types instead of being converted. The latter is also true if you use the GetField<T> extension methods introduced with .NET 3.5.
Examples of method calls that will not break:
C#
Copy
```
long value = SphinxQLDataReader.GetInt64("my_big_int_column");

long value = Convert.ToInt64(DataTable.Rows[0].Columns["my_big_int_column"]);

long value = Convert.ToInt64(SphinxQLDataReader.GetValue("my_big_int_column"));
```
Examples of method calls that will break:
C#
Copy
```
long value = (long) SphinxQLDataReader.GetValue("my_big_int_column"); 

Change to:

long value = SphinxQLDataReader.GetInt64("my_big_int_column");
or 
decimal value = (decimal) SphinxQLDataReader.GetValue("my_big_int_column");
or 
long value = Convert.ToInt64(SphinxQLDataReader.GetValue("my_big_int_column"); 

/*---------------------------------------------------------------------------*/

long value = (long) DataTable.Rows[0].Columns["my_big_int_column"];
and 
long value = DataTable.Rows[0].GetValue<long>("my_big_int_column"); 

Change to:

long value = Convert.ToInt64(DataTable.Rows[0].Columns["my_big_int_column"]);
or    
decimal value = (decimal) DataTable.Rows[0].Columns["my_big_int_column"]
or    
decimal value = DataTable.Rows[0].GetValue<decimal>("my_big_int_column");
```
