   - Expat 2.6.4 (previously 2.6.2)
   - libcurl 8.12.0 (previously 8.9.1)
   - OpenSSL 3.0.16 (previously 3.0.13)
   - rapidjson 20220112 (previously 1.1.0)


Resolved Issues 
The following issue has been resolved in Simba Presto ODBC Connector 
1.4.1.1000.

 * [PRESO-1730] Resolved the data truncation issue for varchar characters.


Known Issues 
The following are known issues that you may encounter due to limitations in 
the data source, the connector, or an application. 

 * Implicit casting of CHAR(x) to larger CHAR(x) is not supported

   Beginning with version 0.152.1-t, Presto does not support implicit 
   casting of CHAR(x) data to a CHAR(x) of a larger size. As a workaround, 
   INSERT queries into columns of CHAR(x) type must contain an 
   explicit cast into a CHAR(x) type of the size reported by the Presto 
   Server.
   
 * [PRESO-681] Some year values not supported in TIME and TIMESTAMP
      
   The connector does not support year values less than -9999 or greater than 
   9999 in TIME and TIMESTAMP data types.


Workflow Changes =============================================================

The following changes may disrupt established workflows for the connector.


1.2.4 ------------------------------------------------------------------------

 * Minimum TLS Version

   Beginning with this release, the driver requires a minimum version of TLS 
   for encrypting the data store connection. By default, the driver requires 
   TLS version 1.2. This requirement may cause existing DSNs and connection 
   strings to stop working, if they are used to connect to data stores that 
   use a TLS version earlier than 1.2.

   To resolve this, in your DSN or connection string, set the Minimum TLS 
   option (the Min_TLS property) to the appropriate version of TLS for your 
   server. For more information, see the Installation and Configuration 
   Guide.
