+Added config option `HeadTracker.FinalityTagBypass` to force `HeadTracker` to track blocks up to `FinalityDepth` even if `FinalityTagsEnabled = true`. This option is a temporary measure to address high CPU usage on chains with extremely large actual finality depth (gap between the current head and the latest finalized block). #added
+
+Added config option `HeadTracker.MaxAllowedFinalityDepth` maximum gap between current head to the latest finalized block that `HeadTracker` considers healthy. #added

 SamplingInterval means that head tracker callbacks will at maximum be made once in every window of this duration. This is a performance optimisation for fast chains. Set to 0 to disable sampling entirely.
 
+### FinalityTagBypass
+```toml
+FinalityTagBypass = true # Default
+```
+FinalityTagBypass disables FinalityTag support in HeadTracker and makes it track blocks up to FinalityDepth from the most recent head.
+It should only be used on chains with an extremely large actual finality depth (the number of blocks between the most recent head and the latest finalized block).

+```toml

+MaxAllowedFinalityDepth - defines maximum number of blocks between the most recent head and the latest finalized block.
+If actual finality depth exceeds this number, HeadTracker aborts backfill and returns an error.
