v0.8.1 - 2017-12-06

v0.8.0 - 2017-12-04

• Remove most deprecations.

• Add new v2 API.

• Move away most of the v1 API, but keep deprecated aliases for the client API.

The main difference of the new API compared to the old is:

• It uses typed parameters and rows with an extensible variant for field type and a custom definable compound type.

• The connection has a call method which gives access to a result object before iterating over the returned rows.

• Error handling is done with the result type, using a collection of error types formed as polymorphic variants of records.

Notice: This version is mostly backwards compatible. New code should use v2, but v1 will be kept for now. To keep using the v1 in upcoming releases:

• Fix the new deprecations from this release.

• Link with caqti-dynload to keep using dynamic loading, or link with the needed caqti-driver-*.v1 driver libraries.

• Link with caqti.v1 instead of caqti.

• Link with caqti-lwt.v1 instead of caqti-lwt.

• Link with caqti-async.v1 instead of caqti-async.

• Remove deprecated findlib aliases.

• Renamed date and utc conversions to date_cl and utc_cl.

v0.6.0 - 2017-06-05

• Fix handling of spaces in Sqlite3 URIs and allow setting mode.

• Split Caqti (now deprecated) into Caqti_errors and Caqti_connect.
