Update Priorities

When publishing releases, Lighthouse will include an "Update Priority" section in the release notes. As an example, see the release notes from v2.1.2).

The "Update Priority" section will include a table which may appear like so:

User Class	Beacon Node	Validator Client
Staking Users	Medium Priority	Low Priority
Non-Staking Users	Low Priority	---

To understand this table, the following terms are important:

• Staking users are those who use lighthouse bn and lighthouse vc to stake on the Beacon Chain.
• Non-staking users are those who run a lighthouse bn for non-staking purposes (e.g., data analysis or applications).
• High priority updates should be completed as soon as possible (e.g., hours or days).
• Medium priority updates should be completed at the next convenience (e.g., days or a week).
• Low priority updates should be completed in the next routine update cycle (e.g., two weeks).

Therefore, in the table above, staking users should update their BN in the next days or week and their VC in the next routine update cycle. Non-staking should also update their BN in the next routine update cycle.
