Difference between 1.x and 2.x branches

The jquery_ui module now hosts the entire jQuery UI library, and that the jquery_ui_datepicker module only forces inclusion of jquery_ui module in a version 1.6 which ships with the jquery ui datepicker. Beside this the version 2.0.0 of the module doesn't do anything else on it's own.

On the other hand the jquery_ui module uses hook_library_info_alter() where it looks at what are enabled jquery ui submodules, and if specific submodule is found, then the jquery UI function is added.

My understanding is that this is for compatibility and for other contribs to be able to add depdendencies for specific functions of the jquery ui. Anways my preference would be to rather enable jquery ui functions using checkboxes in the backend.

the 1.x branch works with languages other than English, uses Drupals t function , and the localization framework

Branch 2.x guts all that and relies 100% on a stripped down datepicker from the jquery_ui module assets that only has english.

The 2.x branch seems like a major downgrade /regression, sacrifices a beautifully perfect localization approach for a botched approach that wasn't even attempted to be implemented.

Can we please scrap the 2.x branch and maintain the 1.x branch and set it back as the recommended approach?

This likely means the newest version of the jquery_ui module is botched as well.

in order to use better_exposed_filters 6.0 and still maintain the superior (functioning localisation) functionality of the jquery_ui_datepicker 1.4 version I'm having to use this composer trick.
"drupal/jquery_ui_datepicker": "1.4 as 2.0.0",

💬 Unable to update to 6.0.3 from 6.0.2 Active

Ok so there is a patch available for jquery_ui that may actually substitute for the functionality that was lost between jquery_ui_datepicker 1.x and 2.x (1.x having the expected localisation functionality whereas 2.x lacking the expected localisation)

The patch is here:
#3339013-26: implement datepicker localisation in jquery_ui 2.x, compare with jquery_ui_datepicker 1.x that has localisation →
