0.10.2 - 2018-04-05

• Fix incompatibility with ppx_optcomp v0.11.0 by dropping it, since the conditionals where no longer needed.
• Restore test during opam build.
• The v1 API is now fully [@@@deprecated] and will be removed in the next major release.

0.10.1 - 2018-02-27

• Fix a pool size counting bug when resource allocation fails. This can cause deadlock due to pool exhaustion.

0.10.0 - 2018-02-14

• Added -linkall flags to driver libraries to fix direct linking (#9).
• Added convenience functions collect_list and rev_collect_list (#8).
• Renamed template to query and related function, leaving deprecated aliases.
• Added ptime_span field type mapping to SQL intervals.
• Be more permissive about types of data returned from MariaDB when expecting numerical results.

0.9.0 - 2018-01-04

• Move v1 into findlib sublibraries and announce deprecation.
• Port remaining tests to v2 and fix issues in MariaDB and Sqlite3 drivers.
• Don't include password component of URIs in error messages.
• Rename io type constructor to future.
• Fix pool size limit enforcement.
• Drop error on disconnect.
• Support substitutions in request convenience functions.

0.8.1 - 2017-12-06

• Fix start transaction for PostgreSQL v2.
• Fix dependency on ptime in caqti.opam in distribution.

0.8.0 - 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.

0.7.0 - 2017-11-03

• Remove WRAPPER and REPORT functionality.
• Remove deprecated findlib aliases.
• Renamed date and utc conversions to date_cl and utc_cl.
• Deprecate Caqti_metadata in favour of the new Caqti_driver_info.
• Move various signature to separate files, leaving deprecated aliases.

0.6.1 - 2017-10-26

• Fixed support for lwt >= 3, but keep supporting 2.7 as well for now.
• Fixed preparation of query after reconnect to PostgreSQL.
• Fixed support for ocaml 4.03.x.
• Added Tuple.length.
• Deprecated Param.sub_types.
• Deprecated Param.other and Tuple.other.

0.6.0 - 2017-06-05

• Split into separate packages to avoid depopts and rename findlib names accordingly.
• Use findlib to load DB drivers, and use -linkall. This hopefully solves loading issues.

0.5.3 - 2017-05-22

• Fix handling of spaces in Sqlite3 URIs and allow setting mode.
• Split Caqti (now deprecated) into Caqti_errors and Caqti_connect.
