Release 1.1.8.20200710

WARNING: Before upgrading to a new version of the driver, make sure you read the release notes of all intermediate versions!

• The baseline version of ClickHouse server used for tests and feature support is set to 20.3 (#304)
• Implemented array binding/bulk fetch support (#302)
• Fixed row and column binding issues (#302)
• Fixed SSL/TLS connection issues in Windows (#305)
• Fixed passing NULL parameters into prepared statements (#304) (potentially breaking change, ClickHouse server must contain the following modification: ClickHouse/ClickHouse#8517)
• Fixed the issue when closing a cursor leaves the statement in an unprepared state
• Fixed the issue when binding columns was not allowed on an unprepared statement

Release 1.1.7.20200414

• Fixed parsing of escape sequences (#283, #284)
• Made ICU the default Unicode conversion back end in Unix builds (#278)
  • Warning 1 (for Unix only): only the system ICU packages are supported right now, which means, that 1) you will need to make sure that the corresponding run-time dependency is installed in your system, 2) system ICU may bring some other run-time dependencies and load additional (system) shared libraries like libstdc++.so and others. If this is not acceptable, you will need to build the driver with ICU disabled, using -DCH_ODBC_USE_ICU=OFF cmake switch.
  • Warning 2 (for Unix only): the pre-built Linux package listed below is built on CentOS 7, and it depends on the default system version of ICU, which is ICU 50. If you plan to use it in any other Linux distribution, you have to make sure, that this exact version of ICU is available at run-time there. Otherwise, you will need to build the driver manually for your system so that it links with its ICU version. The process is trivial, follow the instructions at "Building from sources" section from README.md.

• Fixed display size reporting. #261 (PR #264)
• Applied various performance optimizations. (PR #272 #270)
• Linux package is linked with C++ runtime statically, all internal symbols are hidden now. (PR #267)
• Fixed build issues on some platforms (Ubuntu 18.04, Alpine Linux). #263 #12 (PR #267)

• Added sample Tableau Datasource Customisation (.tdc) file for better driver capability detection

Note for Windows users: If you have issues with using the driver (error 126) you need to install fresh Microsoft Visual C++ Redistributable manually. [#251]
