Considering the up-gradation brought up with the release of Joomla 3.5, v3.7 is foreseen to be a minor upgrade, yet Joomla clearing the air announced shipping of some main new features to be included by Joomla 3.7 , Beta version of which is set to be released around 24th of January 2017.
Joomla! announced  Robert Deutz (CMS maintainer and former PLT member) as the 3.7 Release Lead, with its news publish about its Version 3.7 and what to expect.
Talking in details, we have put together some of the expected features coming up with the version.

• Routing:
  Router is the relevant code to create and process SEF URLs. Search engine friendly (SEF), human-readable URLs that make sense to both humans and search engines because they explain the path to the particular page they point to. Joomla will now have the scope of using a new routing strategy, The feature is placed as an option and you can enable it per component, easing to mix the old and new strategy if required. Joomla! also made it clear that If you are using an old extension that does not support the new routing then everything will still work as before. This will ensure many issues fixes faced with the current version of Joomla!. The update is announced by Joomla! In its Road to 3.7 news publish and will make its way in the new upcoming version.

• Custom fields:
  Talking about custom fields, You will be able to add custom fields to articles, user profiles and contact forms. It will now be possible to attach a field to a field group, disable custom field feature to every component, 3rd party extension developers will be allowed to adapt the output to their extensions and the site integrator to customize them to their needs and much more.
  The new version of Joomla! Will see some significant update about custom fields, We are counting that with the release of this Joomla! 3.7, The coding of the same is pretty much done, and is available to be tested by anyone anyone just by downloading the  version of Joomla! available in GitHub repository.
