MSRV bumped in patch release

[TheBlueMatt]

Does syn provide an MSRV guarantee for a major/minor release? Sadly, it appears the latest patch version bumped the MSRV beyond rustc 1.63 (a somewhat-common MSRV still as its debian oldstable/debian stable from a few months ago), which sadly also corresponds with a version of cargo that can't do automatic dependency resolution based on the dependency MSRV.

Encountering this as well. The last time that 1.65 MSRV was supported was 2.0.106

It's also worth noting the README is still claiming 1.61 is supported.
