Updated to the latest version of GRDB
Fixed an issue with db reentrant behaviour with the Attachment upload function
Finished up the updated 'sendNonDurability' functions
Fixed a couple of issues around the duplicate messages handling
Fixed a few issues with ClosedGroup polling and ClosedGroup control message handling
Started working through updating the MediaGallery
Removed the 'presentTimer' logic from the 'ModalActivityIndicatorViewController' (the delay looked buggy, if it does have "blipping" issues then we can fix those separately)
