backup_migrate 7.x-3.6

This release has a wealth of new of bug fixes, along with some new features. The most notable change is a dramatic reduction in memory requirements during backups, down from possibly multiple gigabytes to ~100mb.

As always, a huge thank you to all contributors, and especially to couturier who has been doing an amazing job on supporting folks on the issue queue.

Important notes

• It was reported that this version can be slower than past releases for exporting backups. This is because of the memory usage optimization, which can cause the backup to take longer. It is worth reviewing the "known issues" section of the README.txt file for some suggestions, in particular increasing the backup_migrate_data_rows_per_query option from its default of 1,000 to 5,000, 10,000 or even 50,000 can help, but be careful to avoid hitting the PHP memory limit or timing out.
• The module now requires PHP 5.4. This was an intentional decision. While the module does not currently take advantage of this, future releases may require newer improvements in the language. Given that PHP 5.4 is over six years old and support ended in 2015, it's time for sites to update.
