The driver has also been enhanced with the new Credentials Wallet Entry (CredentialsWalletEntry), Credentials Wallet Path (CredentialsWalletPath), Wallet Password (CredentialsWalletPassword) options, which are used to configure this feature.
  Note: Oracle Wallet Password Store functionality requires the OpenSSL 1.1.1 library. Earlier versions of the library, including those installed with the driver, are not supported by the feature.
• The driver has been enhanced to support connecting using the connection information stored in an LDAP entry. You can configure the driver to use LDAP with the new LDAP Distinguished Name (LDAPDistinguishedName) option and refreshed Host (HostName) and Port Number (PortNumber) options.
• The Driver Manager for UNIX/Linux has been enhanced to support setting the Unicode encoding type for applications on a per connection basis. By passing a value for the SQL_ATTR_APP_UNICODE_TYPE attribute using SQLSetConnectAttr, your application can specify the encoding at connection. This allows your application to pass both UTF-8 and UTF-16 encoded strings with a single environment handle.*
  The valid values for the SQL_ATTR_APP_UNICODE_TYPE attribute are SQL_DD_CP_UTF8 and SQL_DD_CP_UTF16. The default value is SQL_DD_CP_UTF8.
  This enhancement is available in build 08.02.0449 of the driver manager.
• The curl library files that are installed with the product have been upgraded to version 7.66.0, which fixes a number of potential security vulnerabilities. For more information on the vulnerabilities resolved by this enhancement, refer to: https://curl.haxx.se/docs/vulnerabilities.html.

• The driver has been enhanced to support connecting through Oracle Connection Manager using the TNSNAMES.ORA file.*
• The default OpenSSL library version has been updated to 1.1.1d.*
• The new AllowedOpenSSLVersions option determines which version of the OpenSSL library file the driver uses for data encryption when multiple versions are installed with the product. For example, when specifying a value of 1.1.1 (AllowedOpenSSLVersions=1.1.1) the driver uses the 1.1.1 version of the library that is installed with the driver.*
• The default version of the OpenSSL library has been updated to 1.0.2r.*
• The driver has been enhanced to support connecting to a proxy server through an HTTP connection. HTTP proxy support is configurable with the new Proxy Host, Proxy Mode, Proxy Password, Proxy Port, and Proxy User connection options.*
  Note: The driver does not currently support SSL data encryption for HTTP proxy connections.
• The driver has been enhanced with the new Impersonate User connection option that allows you to specify the proxy user ID used for impersonation. The user ID specified using this option determines your permissions and identity when executing queries.*
• The driver has been enhanced to support using the default Service Name or SID specified in the server-side listener.ora file.*
• The setting of the Array Size option can now be overridden by specifying the number of rows to fetch using the SQL_ATTR_ROW_ARRAY_SIZE statement attribute.*
• Support for Oracle Wallet, including:
  • Oracle Wallet SSL Authentication
  • Using Oracle Wallet as a keystore or truststore for SSL data encryption.
• The driver has been certified to use Oracle Internet Directory as a means to store authentication information.
• The Oracle driver has been enhanced to support the following new data integrity algorithms for Oracle 12c and higher: SHA256, SHA384, SHA512. To use these algorithms, specify their values using the Data Integrity Types connection option and enable data integrity checks with the Data Integrity Level connection option.
  
• The maximum supported length of identifiers has been increased to 128 bytes when connecting to Oracle 12c R2 (12.2) databases. This change has been implemented to reflect the new maximum length supported by the server. 

Changed Behavior 

• The following Windows platforms have reached the end of their product lifecycle and are no longer supported by the driver*:
  • Windows 8.0 (versions 8.1 and higher are still supported)
  • Windows Vista (all versions)
  • Windows XP (all versions)
  • Windows Server 2003 (all versions)
• The default value for the Data Integrity Types connection option has changed to the following: MD5,SHA1,SHA256,SHA384,SHA512.

Version 8.0.1

Certifications

• Debian Linux 7.11, 8.5 (driver version 07.15.0159 (B0270, U0182))
• Ubuntu Linux 14.04, 16.04 (driver version 07.15.0159 (B0270, U0182))
  

Enhancements

• The default OpenSSL library has been updated to version 1.0.2n.*
• The default OpenSSL library has been updated to version 1.0.2k.*
• Support for the Oracle 12 and 12a authentication protocols, which provide improved security.
• Support for returning implicit result sets from stored procedures.
• The driver is now compiled using Visual Studio 2015 for improved security.
• The new SDU Size connection option allows you to specify the size in bytes of the Session Data Unit (SDU) that the driver requests when connecting to the server.
• The new Support Binary XML connection option enables the driver to support XMLType with binary storage on servers running Oracle 12c and higher. 
• The new LOB Prefetch Size connection option allows you to specify the size of prefetch data the driver returns for BLOBs and CLOBs for Oracle database versions 12.1.0.1 and higher. With LOB prefetch enabled, the driver can return LOB meta-data and the beginning of LOB data along with the LOB locator during a fetch operation. This can have significant performance impact, especially for small LOBs which can potentially be entirely prefetched, because the data is available without having to go through the LOB protocol.

Changed Behavior 

• The Enable N-CHAR Support connection option has been deprecated, and the driver behavior has been updated to always provide support for the N-types NCHAR, NVARCHAR2 and NCLOB. For compatibility purposes, the EnableNcharSupport attribute can still be manually specified for this release, but will be deprecated in subsequent versions of the product. 
• The Enable Timestamp with Timezone connection option has been deprecated, and the driver behavior has been updated to always expose timestamps with timezones to the application. For compatibility purposes, the EnableTimestampwithTimezone attribute can still be manually specified for this release, but it will be deprecated in subsequent versions of the product.
• The default value for the Data Integrity Level connection option has been updated to 1 (Accepted). By default, a data integrity check can now be made on data sent between the driver and the database server, if the server request or requires it. This change allows the driver to connect to servers requiring Oracle Advanced Security data integrity checks using the default configuration.
• The default value for the Encryption Level connection option has been updated to 1 (Accepted). By default, encryption is now used on data sent between the driver and the database server if the database server requests or requires it. This change allows the driver to connect to servers requiring Oracle Advanced Security encryption using the default configuration.
