Standard rules:
Normal Sudoku rules apply.
Normal anti-knight rules apply. Digits must not repeat in cells that are a chess knight's move apart.
The grey lines are palindromes that read the same forwards and backwards
Digits along the thermometer increase starting from the bulb
Draw an orthoganally-connected snake from R7C1 to R4C9 that that satisfies the following conditions:
Circles where four cells meet indicate that at least one of those 4 cells must contain a snake cell whose digit is a valid count using the same logic as knight cells.

Lovely snake puzzle which makes good use of all the rules. The 1 to 8 rule was more important in this one than the other snake/loop version. Thanks :-)
It's worth mentioning that this puzzle does not have any Nurikabe rules, but the snake has a space-filling property.

The ending was tough! Kept missing a single knight's move restriction. Glad to see this was re-uploaded. I had started the previous version, and saw it broke after getting the snake. Really enjoyed this!
