1.5.5

Released: February 20, 2021

bug

[bug] Adjusted the use of SQLAlchemy's ".copy()" internals to use "._copy()"
for version 1.4.0, as this method is being renamed.
[bug] [environment] Added new config file option prepend_sys_path, which is a series of
paths that will be prepended to sys.path; the default value in newly
generated alembic.ini files is ".". This fixes a long-standing issue
where for some reason running the alembic command line would not place the
local "." path in sys.path, meaning an application locally present in "."
and importable through normal channels, e.g. python interpreter, pytest,
etc. would not be located by Alembic, even though the env.py file is
loaded relative to the current path when alembic.ini contains a
relative path. To enable for existing installations, add the option to the
alembic.ini file as follows:

sys.path path, will be prepended to sys.path if present.

defaults to the current working directory.
