The change partly goes back to the old behavior for forwards migrations which should reduce the amount of memory consumption (#24745). However, by the way the current state computation is done (there is no `state_backwards` on a migration class) this change cannot be applied to backwards migrations. Hence rolling back migrations still requires the precomputation and storage of the intermediate migration states. This improvement also implies that Django does not handle mixed migration plans anymore. Mixed plans consist of a list of migrations where some are being applied and others are being unapplied. Thanks Andrew Godwin, Josh Smeaton and Tim Graham for the review as well as everybody involved on the ticket that kept me looking into the issue. |

The documentation in this tree is in plain text files and can be viewed using any text file viewer. It uses ReST (reStructuredText) [1], and the Sphinx documentation system [2]. This allows it to be built into other forms for easier viewing and browsing. To create an HTML version of the docs: * Install Sphinx (using ``pip install Sphinx`` or some other method) * In this docs/ directory, type ``make html`` (or ``make.bat html`` on Windows) at a shell prompt. The documentation in _build/html/index.html can then be viewed in a web browser. [1] http://docutils.sourceforge.net/rst.html [2] http://sphinx-doc.org/
