Log Message:
Update to 1.4.0. From the changelog:

- Fixed Snowflake warehouse and role setup to properly quote identifiers
  unless they're valid unquoted identifiers or already quoted. Thanks to
  @marc-marketparts for the report (#685).
- Fixed a bug reworking a change when a rework directory is configured
  but not created. Thanks to @jfeaver for the report (#686).
- Output the list of changes to be deployed or reverted when `--verbose`
  is specified at least twice. Thanks to @vectro for the PR (#702).
- Fixed the formatting of the log and plan commands to allow empty or `0`
  separators in lists of things (such as `%{0}t` for a list of tags).
  Thanks to @web-vertalo for the pull request (#703).
- Updated the MySQL Tutorial to use 5.7 features. Thanks to Vlad
  Safronov for the PR (#705).
- Deprecated the `no_prompt` and `no_prompt` attributes of
  App::Sqitch::Engine in favor of passing booleans to the `revert` and
  `verify` methods. The attributes still exist for reverse compatibility,
  but now emit warnings and will be removed in the future. Thanks to
  Thanks to @vectro for the PR (#704).
- Added a warning for a double extension on the file names created
  by the `add` command. Thanks to @blairjordan for the PR (#724)!
- Added the `revert.strict` boolean configuration variable which, when
  set to true, requires the specification of a change to revert to. It
  also disables the `rebase` and `checkout` commands, though the
  `rebase.strict` and `checkout.strict` variables, respectively, may
  override it. Use `revert.strict` to prevent accidental reverts in
  sensitive environments. Thanks to @vectro for the PR (#719; revised in
  #735)!
- Fixed test failures due to a bug fix in the Perl URI module
  (libwww-perl/URI#13). Thanks to @bobfang for the report (#744)!
- Fixed test failures due to a change in the generation of DBI DSN by
  URI::Oracle introduced by libwww-perl/URI-db#23.
- Added a format option `%F` to `sqitch plan` that prints the path for
  the deploy file for each migration in the plan.
- Changed the default location for the Oracle `sqlplus` client when the
  `ORACLE_HOME` environment variable is set. It now returns either
  `$ORACLE_HOME/bin/sqlplus` or `$ORACLE_HOME/sqlplus` if it exists
  and is executable (and ends in `.exe` on Windows). Otherwise it simply
  returns `sqlplus` as before, assuming it will be found in the path.
  Thanks to @vectro for the suggestion (#747).
- Increased the required version of DBI to 1.631 or higher and removed
  a MySQL engine workaround for older versions.
- Added detection of a missing registry schema on connect and conditions
  to avoid querying it when it does not exist. Fixes an issue where
  Sqitch might find a project record in the current schema instead of the
  expected registry schema. Thanks to @vectro for the report and
  investigation (#668)!
- Fixed Snowflake and MySQL to properly raise errors on session query
  failures immediately after connection.
- Fixed the handling of unique violations for deploy script hash
  uniqueness so that it no longer returns a database error but properly
  reports the issue in a more human-friendly error message. Thanks to
  Stefan Badenhorst for the reminder (#630).
- Updated the registry SQL scripts for Vertica to always enable primary
  key and unique constraints. Unique constraints are now enabled for
  all database engines except Exasol and Snowflake.
- Dropped support for Vertica 7.1, as unique constraint enforcement was
  not added until Vertica 7.2.
- Increased minimum SQLite versions to 3.8.6, when unique constraint
  enforcement was added.
- Removed remaining uses of the smartmatch operator, thus eliminating
  the Perl 5.38 warnings about its deprecation. (#769)
- Added Cockroach to the list of valid engines recognized in command-line
  arguments (and a test to ensure new engines won't be omitted in the
  future). Thanks to @NOBLES5E for the spot (#772)!
