v2026.05.6

Apologies for the amount of updates this month... Ironing out issues with the more advanced role and subscription checking.

This particular update is only needed when you encountered issues with the v2026.05.3, v2026.05.4 or v2026.05.5 versions; typically when using a free DAB Pumps account. Optional for everyone else.

• Fix inconsist coding of roles in cached device config params
