3. Lightning App Builder – Dynamic Forms Add related object fields • Max two levels • Not polymorphic relationships Set field visibility by device Auto-enabled for mobile in new orgs See fields object relationship/API name 31/01/2024 3
4. Lightning Web Components Reminder - component level versioning • Component behaviour matches API version in config • 58.0 or earlier = 58.0 • Later than org API = current release Empty comment nodes replace empty text nodes • E.g. scoped slots, lwc:if • Check and update UI tests 31/01/2024 4 <template> <template lwc:if={showWelcome}>Welcome</template> </template> "Welcome" <!----> "Welcome" <!---->

8. Apex UUID class • Version 4 Universally Unique IDentifier • Cryptographically strong pseudo-random number generator • 32 character hexadecimal string • Collisions highly unlikely • Ideal where uniqueness + unpredictability are required • No metadata so cannot identify context 31/01/2024 8
9. LWC Mixed Shadow Mode Custom components default render in synthetic shadow mode • Polyfill of shadow DOM that works cross browser • Most modern browsers now support native shadow mode Improves speed - "native components are up to 50% faster" Reduce LWC side by half – eventually, when synthetic polyfill removed Set shadowSupportMode to 'native' to force native shadow mode • All child components use native shadow mode too • May break if child doesn't support native • Don't use with base Lightning components 31/01/2024 9
