This minimum version increase sounds reasonable.

Fixed with interval-3.2.1.

The patch has been applied in the repository, thank you very much for the preparation.

According to [1] the error_state has been replaced by the exception mechanism in 2016 with Octave 4.2.  Thus, the minimum Octave version of the package should probably be increased from 3.8 to 4.2.

Or am I missing something?

Quoting jwe from bug #61551:

> The global 'error_state' variable has been useless for quite some time now.  It's been removed on the default branch (what will become version 8.1 in about a year).  Since about 6 years ago, it has never had a value other than 0 in Octave code and is no longer useful for checking whether an error has occurred because exceptions are thrown, so checking the state of a variable after an error occurs is not useful except inside a 'catch' clause that handles 'octave::execution_exception'.
> All uses of this variable should be removed from the video package and any other packages that still use it.  You should have been seeing a warning at compile time about it being deprecated since before version 6 was released (it was marked as deprecated in May 2019).

This also applies to the interval package.
I'll attach a possible patch as soon as I'll have a bug number.
