In the course of improving my answer to 95361, I noticed that the DSolve documentation on the web is much better written than that distributed with Mathematica 10.2.0 for Microsoft Windows (64-bit) (July 7, 2015). Moreover, it describes a more powerful version of DSolve, one that accepts Assumptions as an option and can solve Sturm-Liouvlle Problems, for instance. My questions are

  • Are this better version of DSolve and its documentation available for download?
  • Do other functions have updated versions and documentation not part of the current release of Mathematica?
  • Does documentation exist for DSolve Method?

    $\begingroup$ At the bottom of the documentation distributed with Mathematica 10.2.0 one can find the information "Introduced in 1991 (2.0) | Updated in 2014 (10.0)". There isn't such an information on the web documentation, whereas such information is also available in the web documentation for other functions (for example for Solve). $\endgroup$ – Karsten 7.

    $\begingroup$ There are currently many updated Documentation Center pages on the WEI site that discuss new functionality and even new functions. I guess WRI is getting close to a new release. There was similar activity on the WRI site when V10 was near release. $\endgroup$ – m_goldberg Oct 3 '15 at 19:40
  • $\begingroup$ In the web documentation, while the option Method appears under the Details and Options section, Method is not a listed option under the Options subsection of the Examples section. $\endgroup$ – Bob Hanlon Oct 3 '15 at 20:46

    $\begingroup$ @bbgodfrey - I was merely pointing out an inconsistency in the web documentation which presumably might indicate that the Method option and/or its documentation may not be finalized. $\endgroup$ – Bob Hanlon Oct 3 '15 at 20:58

This improved version of DSolve and its documentation will be part of Mathematica 10.3 as can be seen in the Summary of New Features in 10.3. There you'll also find which other functions will get updated and which new functions will be introduced. From my experience the web documentation for these functions will get updated prior to the release of the new version.

    $\begingroup$ Unfortunately the Method option isn't well documented for too many functions. $\endgroup$ – Karsten 7. Oct 5 '15 at 0:15
