When I do not find any article regarding the same, I asked my systems people to give me a test machine. I installed ODP.net 10.2 on the same machine. There in the docs, I found release notes. I am posting these release notes below :
Copyright (C) Oracle Corporation 2006
This document provides information that supplements the Oracle Data Provider for .NET (ODP.NET) documentation.
The following features have been added or removed since ODP.NET 10.2.0.2.10 beta:
1. System.Transactions Support (ODP.NET for .NET Framework 2.0 only)
ODP.NET for .NET Framework 2.0 supports System.Transactions. However,ODP.NET does not promote transactions from local transactions to distributedtransactions. This means that when System.Transactions is used, the transactionbecomes a distributed transaction immediately, even if only one resource manager is used. If applications use System.Transactions, it is required that the "enlist" connection string attribute be set to either "true" (default) or "dynamic".
2. Provider-specific Type NULL support (ODP.NET for .NET Framework 2.0 only)
ODP.NET supports provider-specific NULL Types. If the application requests for provider-specific types to be retrieved from an OracleDataReader or an OracleParameter or populated into a DataSet, NULL values will be represented as provider-specific NULL values. Provider-specific NULL values are accepted as input parameter values and can also be returned as output parameter values. Note that ODP.NET for .NET Framework 1.x will continue to represent NULL valuesas DBNull.Value.
3. OracleDbType.BinaryFloat & OracleDbType.BinaryDouble Support (ODP.NET for ADO.NET 1.x and 2.0)
ODP.NET supports new OracleDbType enumeration values of BinaryFloat and BinaryDouble which can be used when binding data for BINARY FLOAT or BINARY DOUBLE parameters.
4. Windows Registry Changes (ODP.NET for .NET Framework 1.x and 2.0)
Default registry values for ODP.NET now reside under HKEY_LOCAL_MACHINE\Software\Oracle\ODP.NET\
5. DllPath Registry Value (ODP.NET for .NET Framework 1.x and 2.0)
The Oracle.DataAccess.dll searches for dependent unmanaged DLLs (i.e. Oracle Client) based on the following order:i) directory of the application/executableii) directory specified by HKEY_LOCAL_MACHINE\Software\Oracle\ODP.NET\
Upon an install of ODP.NET, the DllPath registry value of type REG_SZ will be set to the %ORACLE_HOME%\bin directory where the corresponding dependent DLLs are installed.
Note that the DllPath registry value takes effect only on Windows XP, Windows Server 2003, and Windows Server 2003 R2. If ODP.NET is installed on Windows 2000, ODP.NET will simply rely on the application directory and PATH for loading dependent unmanaged DLLs.
6. ODP.NET and Dependent Unmanaged DLL Mismatch (ODP.NET for .NET Framework 1.x and 2.0)
To enforce the proper usage of Oracle.DataAccess.dll assembly with properunmanaged DLLs, an exception will be raised if Oracle.DataAccess.dll notices it has loaded a mismatching version of a dependent unmanaged DLL.
7. UDT/Objects Support (ODP.NET for .NET Framework 1.x and 2.0)
This feature has been removed for 10.2.0.2.20.
1. Database Change Notification
When an OracleCommand registers for a Change Notification, statement caching will be disabled for that execution.
2. Batch Processing (OracleDataAdapter.UpdateBatchSize)
Update batches executed with large amounts of data may encounter an "PLS-00123: Program too large" error. To avoid this error, reduce the sizeof UpdateBatchSize to a smaller value.
3. XML DATE and TIMESTAMP Based on Standard XML Schema
Starting with Oracle Database 10g Release 2, the generated XML DATE and TIMESTAMP formats will not be based on database server settings. They will now be based on the standard XML Schema formats.
For more information on the XML DATE and TIMESTAMP formats in the XML Schema specification, seehttp://www.w3.org/TR/2004/REC-xmlschema-2-20041028/datatypes.html#isoformats
For more information on DATE and TIMESTAMP formats in generated XML, read Oracle XML DB Developer's Guide.
4. System.Transactions Support
Implicit Distributed Transaction Enlistment Using TransactionScope sample lists the connection string attribute Enlist as "Dynamic". It should be changed from "Dynamic" to "True" (default).
TIPS, LIMITATIONS AND KNOWN ISSUES
1. OracleDbType.Single parameter type supports six precisions.
2. Use /*+ ... */ as the optimizer hint syntax. Hint syntax, --+ ... is not supported.
3. Data truncation errors can be encountered when fetching LONG data from a UTF8 database. [bug #2573580].
4. To minimize the number of open server cursors, explicitly dispose OracleCommand, OracleRefCursor, and OracleDataReader objects. 5. When using SQL with "FOR UPDATE" or a "RETURNING" clause, use explicit transactions. This is not required if global transactions are used.
6. For distributed transactions, ODP.NET does not support proxy authentication without a client password because of an OraMTS limitation.
7. OS Authenticated connections are not pooled by ODP.NET, even if pooling is enabled.
8. Thread.Abort() should not be used, as unmanaged resources may remain unreleased, which can potentially cause memory leaks and hangs.
9. Data truncation errors can be encountered when fetching LONG data from a UTF8 database. [bug 2573580].
10. PL/SQL LONG, LONG RAW, RAW, VARCHAR data types cannot be bound with more than 32512 bytes. [bug 3772804, 3639234]
11. Having a command execution terminated through either the invocation of OracleCommand's Cancel method or expiration of OracleCommand's CommandTimeout property value may return ORA-00936 or ORA-00604, rather than the expected ORA-01013. [bug 3715959]
12. An exception is not thrown when change notification is registered on a bad port number [bug 4129077]
13. OracleDataAdapter accumulates memory when UpdateBatchSize property is set to a non zero value and OracleDataAdapter is used to transmit the changes to the Database. Disposing the OracleDataAdapter object after the update frees the memory. (ODP.NET for .NET Framework 2.0 only)
And for the reference purpose, Below are the release notes for ODP.net 9.2.
This document provides information that supplements the Oracle Data Provider for .NET (ODP.NET) documentation.
IMPORTANT INSTALLATION INFORMATION
ODP.NET 126.96.36.199.00 depends on Oracle Client 188.8.131.52.0 that is installed on top of Oracle Client 184.108.40.206.0 or higher.
VS.NET Help Integration
The reference sections of ODP.NET documentation has been integrated with VS.NET IDE help system. This integration will allow developers to search and view information regarding ODP.NET classes and structures from within the VS.NET IDE.
BUG FIXES (in 220.127.116.11.00)
1. Unmanaged exceptions return -3000 without further information. [Bug #4066828]
2. ODP.NET -3000 errors under heavy load. [Bug #4020081]
3. Bind variable (OUTPUT) initialized with blanks using ParameterDirection.Output. [Bug #3930596]
4. Exception ORA-1034 (ORACLE NOT AVAILABLE) after starting the database. [Bug #3908190]
5. ODP internal error -3000 in ExecuteReader() method. [Bug #3893458]
6. Internal error (-3000) when requesting globalization information after Connection is freed. [Bug #3833810]
What's new in 18.104.22.168.01 version
1. XML support in ODP.NET. With XML support, ODP.NET can now: - Store XML data natively in the database server as the Oracle database native type, XMLType. Only non-schema based XMLType will be supported in this release. - Access relational and object-relational data as XML data from an Oracle Database instance into Microsoft .NET environment, process the XML using Microsoft .NET framework. - Save changes to the database server using XML data.
2. Support for PL/SQL Associative Array Binding. ODP.NET supports PL/SQL Associative Array (formerly known as PL/SQL Index-By Tables) binding. An application can bind an OracleParameter, as a PL/SQL Associative Array, to a PL/SQL stored procedure using several OracleParameter properties.
3. Support for validation of pooled connections ODP.NET has introduced a new connection string attribute "validate connection" that should be set to true in order to validate connections coming out of the pool. By default, this property is set to false.
Note that validation causes a round trip to the database for each connection coming out of the pool, which is very expansive in terms of performance. Therefore, this attribute should be used only if absolutely necessary.
4. Support for LOB retrieval using an InitialLOBFetchSize property that provides better performance.
