Summary of important user-visible changes for version 8 (yyyy-mm-dd): --------------------------------------------------------------------- ### General improvements - Octave's libraries are now built using symbol visibility by default. That means that less symbols are exported from these libraries. Configure with `--disable-lib-visibility-flags` to export all symbols (as in previous versions). - `integral` can now output a second argument passing the error measurement used by the underlying integrator. - `perms` now accepts a second argument "unique" to return only unique permutations for inputs with repeated elements. It is faster and takes less memory to call `perms ('aaaabbbbcccc', "unique")` than to call `unique (perms ('aaaabbbbcccc'), "rows")`. - `quadgk` can now accept the `ArrayValued` input parameter to handle array-valued input functions. ### Graphical User Interface ### Graphics backend - Additional properties have been added to the `figure` graphics object: * `"innerposition"` (equivalent to `"position"`) * `"windowstate"` (not yet implemented) ### Matlab compatibility - `inline` functions now support all Matlab methods. The performance of `inline` functions has also been improved. - `sub2ind` now supports index values outside of the size specified by the subscripts. - `cylinder` now accepts a scalar for the radius argument. - `clock` now has an optional second output `ISDST` which indicates if Daylight Savings Time is in effect for the system's time zone. - `print` now accepts option `-image` to specify the "opengl" renderer and `-vector` to specify the "painters" renderer. - `format` now accepts the option "default", which is equivalent to calling `format` without any options to reset the default state. - `quadgk` now stops iterating when `error <= tolerance` while the previous condition was `error < tolerance`. - `var` and `std` now optionally output a second argument containing the mean or weighted mean. - `integral` can now accept the 'ArrayValued' option in combination with 'RelTol' and 'WayPoints'. - The default state for certain graphics properties has been made consistent with Matlab. Object | Property | Default State ------------|------------------|------------ `figure` | `"dockcontrols"` | `"on"` ### Alphabetical list of new functions added in Octave 8 * `uifigure` ### Deprecated functions, properties, and operators The following functions and properties have been deprecated in Octave 8 and will be removed from Octave 10 (or whatever version is the second major release after 8): - Functions Function | Replacement -----------------------|------------------ `shift` | `circshift` `sparse_auto_mutate` | none (see below) - The `sparse_auto_mutate` function no longer has any effect on Octave's behavior. Previously, after calling `sparse_auto_mutate (true)`, Octave would automatically convert sparse matrices to full when a sparse matrix required more memory than simply using full matrix storage. This setting was `false` by default for compatibility with Matlab. Now you must manually convert to full storage when desired. - Properties The following property names are discouraged, but there is no fixed date for their removal. Object | Property | Replacement -----------------|-------------|------------ `uimenu` | `label` | `text` `uimenu` | `callback` | `menuselectedfcn` The following functions were deprecated in Octave 6 and have been removed from Octave 8. - Functions Function | Replacement -----------------------|------------------ `runtests` | `oruntests` - The environment variable used by `mkoctfile` for linker flags is now `LDFLAGS` rather than `LFLAGS`. `LFLAGS` was deprecated in Octave 6, and will be removed in a future version of Octave. ### Old release news - [Octave 7.x](etc/NEWS.7) - [Octave 6.x](etc/NEWS.6) - [Octave 5.x](etc/NEWS.5) - [Octave 4.x](etc/NEWS.4) - [Octave 3.x](etc/NEWS.3) - [Octave 2.x](etc/NEWS.2) - [Octave 1.x](etc/NEWS.1)
