In the latest version [2.0.4] of htmx, several enhancements and fixes were implemented. Notably, calling htmx.ajax with no target or source defaults to the body, nested shadow root issues were addressed, and the htmx:trigger event now properly fires on the synthetic load event without re-calling it. Boosted tags that issue a GET request with no or empty action attributes will replace all existing query parameters correctly. Extension updates include a reworked preload extension, updates to response-targets, ws fixes, and head-support compatibility with the sse extension. Overall, these updates aim to improve the functionality and compatibility of htmx for users.
