== 🎯 Goals for upcoming releases ==

As discussed in the [[Online Developer Meeting (2020-10-27)]], this wiki section is for a list of possible goals for the next release.  Although anyone may edit the wiki, '''this section is intended for active developers, not a place to dump wishlist items or feature requests'''.  Please create a subsection for your ideas/priorities.

:''See also [[JWE Project Ideas]] for additional info about some of these items.''

==== Large New Features ====
* Compatible arguments block ([https://savannah.gnu.org/bugs/?func=detailitem&item_id=59405 some work has been done]; need to execute actions when functions are called)
* Compatible local functions
* Compatible string class
** Define class itself ([[https://github.com/apjanke/octave-tablicious/inst initial implementation]?)
** Construct strings objects from double quoted strings (painful transition).
* Compatible table class ([https://github.com/apjanke/octave-tablicious initial implementation]?)
* Create a low-level interface to HDF5 functions
** Support Matlab's HDF5-based MAT file format using the proposed low-level interface to HDF5 functions
** Allow all types of function handles to be saved and loaded
** Allow [[classdef]] objects to be saved and loaded
* Make import feature work
* Use classdef for handle graphics?

==== Internal Improvements ====
* Refactor/rewrite code for handling load path
* Refactor/rewrite exist and which functions
* Refactor function objects
* Refactor broadcasting and make it work for sparse matrices
* Replace the [[GUI terminal widget|terminal widget in the GUI]]
* Write stack-based byte-code interpreter that doesn't result in deeply nested function calls to evaluate code
* JIT compiler
* Move more code inside octave namespace
* Eliminate mutable class data where possible
* Eliminate singleton objects

==== Other ====
* Bug fixes, especially those related to compatibility issues
* Work through the open bug reports for which patches have been submitted - review/apply/reject and close as many of these reports as possible
