What's new in this version:

New:
- Symbol#toString is now Symbol(foo) instead of the deprecated single-quote form 'foo

Bugfixes:
- Fix 2.13-only bug in Java collection converters that caused some operations to perform an extra pass
- Fix 2.13.2 performance regression in Vector: restore special cases for small operands in appendedAll and prependedAll
- Increase laziness of #:: for LazyList
- Append trailing / when processing unicode escapes
- Respect @uncheckedVariance in higher-kinded types (fixing 2.13.2 regression)

Warnings and linting:
- Deprecate auto-application of (non-Java-defined) methods with a single empty parameter list
- The PR has instructions for suppressing the warning if it is unwanted
- Warn by default on mismatch of presence/absence of an empty parameter list when overriding
- -Xlint:nullary-override is no longer accepted, since this now warns by default
- Discourage multi-argument infix syntax: lint applications (x op (a, b)), also lint operator-name definitions
- Fix @nowarn to use correct semantics for &
- Make -Wunused:imports work again even when -Ymacro-annotations is enabled
- Replace -Wself-implicit with -Xlint:implicit-recursion
- Under -Xsource:3, disallow auto-eta-expansion of SAMs
