[PonyORM-list] Pony ORM Release 0.7

[Alexey Malashkevich]

Hi all,

This is a very special release. We are excited to announce that

Starting with this release Pony ORM is release under
the Apache License, Version 2.0!

Previously we were using the AGPL and commercial licenses and found that
it was driving away contributors and “open source zealots”. Pony is a
mature library which is used by many companies in a production mode.
We’d like to grow a community around Pony ORM, and that is why we've
decided
to release it under a permissive license, such as Apache 2.0.
The Apache License allows you to freely use, modify, and distribute any
Apache licensed product. You can use Pony ORM in your commercial products
for free.

In this article (https://goo.gl/XOZUYi) you can find more information about
the Apache license.

Besides this, here is the list of changes, improvements and bug fixes
included
into this release:

- Added getattr() support in queries
https://docs.ponyorm.com/api_reference.html#getattr

Fixed https://github.com/ponyorm/pony/issues/159: exceptions happened
during flush() should not be wrapped with the CommitException
Before this release an exception that happened in a hook , could be raised
in
two ways – either wrapped into the CommitException or without wrapping.
It depended if the exception happened during the execution of flush() or
commit() function on the db_session exit. Now the exception happened inside
the hook never will be wrapped into the CommitException.

Fixed https://github.com/ponyorm/pony/issues/190: Timedelta is not
supported
when using pymysql


To install the updated version use the following command:

pip install --upgrade pony


Best,
Pony ORM Team
