Note di rilascio per la versione 2.3.2.1

This maintenance release fixes some bugs, mostly on the Mac version.

Usability / UX:

1. [Mac] "Crawl sitemap": adjusted height of dialog windows as the OK/Cancel button were partially hidden.
2. [Mac] "Crawl multiple sites": adjusted height of dialog windows as the OK/Cancel button were partially hidden.
3. [Mac] Images Inspector: in the 2-level tree views, pie charts and labels spaces as in the Windows version.
4. [Mac] Links Inspector: in the 2-level tree views, pie charts and labels spaces as in the Windows version.

Various:

1. [Mac] Licensing: use the computer name instead of the bonjour name to generate the hardware signature to which licenses are bound.
   The previous approach had a drawback because occasionally the system changed the computer share name to resolve potential conflicts, invalidating the product license.
   The down side is that some macOS paid licenses will be invalidated, and users will have to re-insert their activation code (we will contact them).

Fixes:

1. Fixed crashing condition occurring on some machines when trying to display histogram data with extremely thin bars.
2. [Mac] Data Extraction, fixed crashing regression that occurred when launching the feature.
3. Crawling, external images where explored when the options "Crawl external links" and "Crawl images" were selected, but their content was not downloaded.
4. Export to Excel: fixed bug that in some cases caused columns of type DateTime and TimeSpan non being formatted correctly.
5. [Mac] Crawl options: Mac version didn't permit specifying a max crawl depth of zero (i.e. crawl the Home Page only).
   Of course one could have always set the maximum number of pages to 1 and get the same result.
6. [Mac] Fixed a regression in the Image Optimizer, where for some image formats the preview was all blank or all black.
7. Images Inspector: in the 2-level tree views, at the change of the language the label text of the counter field above the tree view was not correctly updated with the right translations.
8. Images Inspector: in the 2-level tree views, at the change of the language the label text of the counter field above the tree view was not correctly updated with the right translations.
9. On language change, histogram titles did not get updated with the new language text.
10. On language change, the main window title did not get updated with the new language text.
