Highlighted changes in this version

UI changes

• The table viewer was improved and does now provide a categoricaly conditional cell colouring scheme

• The terminal history has now a search bar

• It is now possible to hide the main window using set windowshown=false and unhide it again. Using set appautoclose=true, the app will automatically close itself, once the last open window has been closed. Note that those settings are not saved and only affect NumeRe for the current running session.

New and improved functionalities

• remove may now also remove folders (and folder structures recursively)

• k means clustering is now available as table method TAB().kmeansof(...)

• New functions: uuid(), strjoin(), getdisplayscale(), is_void(), is_equal(), is_ordered(), is_unique()

• New statistical functions: rms(), skew(), exc(), stderr(), inv_pct()

• New time-specific functions: today(), get_utc_offset(), is_daylightsavingtime(), is_leapyear()

• New noise functions: ridgedmulti(), billownoise(), voronoinoise()

• Functions for converting between different numerical data types and for creating categories were added.

• NumeRe can now interact with databases using the command database. Available interfaces for now are: MySQL/MariaDB, SQLite, ODBC. PostGreSQL is NOT supported right now due to dependency issues.

• Table method updates: Table method modifiers .scwin() and .srwin() have been added and can be used to define a moving window for multi argument functions. Table method handling has been improved and chaining with the new internal method system is now possible. The new table method modifier .cells() together with .rows or .cols allows for selection of table cells along the direction of application.

• Table columns can now have (physical) units to represent data even better. The units will be detected automatically (if possible), or you can use the dedicated methods to modify the unit of each column.

• Tables may now be exported in MarkDown and HTML format and it's now also possible to copy only a part of a table to another table at a desired location using TAB(i1:i2,j1:j2) = TAB2(i1:i2,j1:j1) syntax.

• Local variables may now also be declared within control flow blocks. Note that they are only declared for the first time per execution the control reaches their command.

• Index-based for loops can now have an additional condition as their second argument (i.e. for (i = 1:0, a != b)), which is checked before each loop iteration.

• The interaction between custom windows and the window command has been cleaned and improved. Some interactions will now return more fitting data types. It might be possible that this change will break some existing solutions. Furthermore, the textfield can now be configured as type=markup to support simplified markdown styling.

• The tabs created with group -style=tabs ... in window layouts can now have an ID and an onchange event handler firing when the user changes the tab. It is also possible to access the properties of the tab group using window ... -get and window ... -set.

• The window command option options={KEY-VALUE-LIST} can be used to modify additional window element properties. This option is currently only supported for tablegrid elements, where one can change the minimal number of rows and cols.

Experimental features

• Clusters can now be created as hierarchical data structures, i.e. clusters can now contain clusters in their fields. You can use the .sel(ID) method for navigating and .unwrap to unwrap the whole structure in a single-level cluster. Writing a set of values into a single cluster element will embed them as a sub-structure. Reading this single element, will return the embedded structure.

General changes

• The kernel was greatly rewritten and supports much more different types and functionalities. Strange typing problems shouldn't appear any more. Overall performance should be improved (although at the cost that some segments might run slower)

• We now only provide a 64 bit version due to limitations of external libraries

• We'll now provide an up-to-date PDF documentation with every new release (including this one)

• A Report an issue feature has been added, which you can use even without an GitHub account

• Many improvements and fixes

Remarks

• This is a beta version. Some features are subject to change. If you experience problems, please let us know

• If you experience troubles with downloads from SourceForge (esp. via MS Edge for Business), consider downloading from Github directly (see assets section at the end of the release notes).

If you have any wishes for the future, please let us know! Either by eMail, Discord or directly entered into the ticket system. They will be heard in any case!

The main changes can be found in the ChangesLog.

An overview can be found below, the details as always in the attached ChangesLog.

• Animations of data sets and tables are now possible

• The detect command can be used to find structures in 2D data

• The pso command provides a particle swarm optimizer for functions with up to four dimensions

• There are commands to rotate images (imrot), datasets (tabrot) and data grids (gridrot)
