Fulcro RAD 1.1.0 released to Clojars Version 1.1's main change is an upgrade of an external js dependency that was a little rough: js-joda. The date-time formatting was manually rewritten to be CLJC to use browser Intl instead of having to have the (rather large) js-joda localization file. This means the internationalized date formatting has a MUCH smaller build footprint, but IF you use localized date PARSING that requires a locale (e.g. isn’t just numbers), AND you are using the RAD data-time namespace to build a DateTimeFormatter, then you need to switch you code to use cljc.java-time directly instead.
