v3.1

• Update cpp-driver to 2.8.1
• write_bytes_high_watermark and write_bytes_low_watermark options were removed
• pending_requests_high_watermark and pending_requests_low_watermark options were removed
• the following stats are removed: available_connections, exceeded_pending_requests_water_mark, exceeded_write_bytes_water_mark

v3.0

• Update cpp-driver to 2.7.1
• Add support for Schema metadata api
• Return column names and types along with results (breaks compatibility with previous versions)
• Add support for retry policy settings

Compatibility changes: This versions breaks the API. All query results will return in case of success:

• ok instead {ok, []} for all DDL and DML queries (because they never returns any column or row)
• {ok, Columns, Rows} instead {ok, Rows}, where also each row is encoded as a list not as a tuple as was before.

v2.9

• Updated cpp-driver to 2.7.0
• Updated lager to 3.4.2
• Fix for segmentation fault when we try to bind more arguments than we specified (#14).
• API breaking changes:
  • non prepared statements are executed now using query/1, query_async/1 and query_new_statement/1 (used when should run inside a batch)
  • the following methods are removed: async_execute_statement/1, async_execute_statement/3, execute_statement/1
  • removed support for binding non prepared statements.
• Add support for user-defined type (UDT): decode as proplist.
• Major code refactoring in the way the nif terms are bind in native cass statements

v2.8

• Updated cpp-driver to 2.5.0
• Updated lager to 3.2.4
• Fix several bugs in compiling scripts
• Don't throw exception in case of bad arguments. Return {error, badarg} instead
• Add more descriptive errors in case of bad options
• Add versions for async_execute where caller can specify the process that's going to receive the response and the tag used to match
  the request with the response.
• Add support for fire and forget async requests (response is never sent back, it's only logged in case fails). Use ReceiverPid = null in
  async_execute/5 or async_execute_statement/3.

v2.7

• Integrated lager as dependency
• Improved logging system. In case the logging process it's crashing it's restarted
• Removed support for the following methods: set_cluster_options/1, create_session/1, and set_log_function/1
• Proper restarting erlcass process in case dies and also reprepare all statements again

v2.6

• Improved performances for gen_time/0, gen_random/0 and gen_from_ts/1 from erlcass_uuid
• Small internal refactoring for constants

v2.5

• Updated cpp-driver to 2.4.3 (require c++ 11)
• Compatible with both rebar and rebar3

v2.4

• Updated cpp-driver to 2.4.2
• Improved the native code build speed
• Add support for setting serial consistency level

v2.3

• Removed the necessity of gen_server calls for prepared statements. Observed this as being a bottleneck under heavy load.
• Removed from erlcass module all methods starting with uuid_* and date_from_epoch/1, time_from_epoch/1, date_time_to_epoch/2. Instead this functions you can use the one from erlcass_uuid and erlcass_time modules.
• Updated cpp-driver to 2.3.0
• Internal code refactoring

v2.2

• Changed the default consistency from CASS_CONSISTENCY_ONE to CASS_CONSISTENCY_LOCAL_QUORUM
• Updated the cpp-driver to 2.2.0
