[dependabot]

Bumps github.com/pb33f/libopenapi from 0.16.13 to 0.18.1.

Release notes

Sourced from github.com/pb33f/libopenapi's releases.

v0.18.1

Fixes a small off by one error in the resolver.

Also adds extension support to server variables that was missing, courtesy of @​geffersonFerraz

v0.18.0

Fixes some memory issues with string allocations. Utility functions were causing a surge of memory when run repeatedly.

Also upgrades the rolodex to use the real name of the root file, instead of 'root.yaml'

Fixes an error that was hard-coded into the License object. Also adds Extensions to License and Contact objects.

No breaking changes, no signature changes.,

v0.17.0

Support for go 1.23 and the new range over function https://tip.golang.org/wiki/RangefuncExperiment feature.

A selection of new methods have been added to the orderedmap package.

• FromOldest()
• FromNewest()
• KeysFromNewest()
• ValuesFromNewest()
• KeysFromOldest()
• ValuesFromOldest()

This allows the range method to be used to iterate ordered maps.

Previously

for pair := orderedmap.First(schema.Properties.Value); pair != nil; pair = pair.Next() {
    buildProps(pair.Key(), pair.Value(), props, 0)
}

In v0.17+

for name, schemaProxy := range schema.Properties.Value.FromOldest() {
    buildProps(name, schemaProxy, props, 0)
}

@​TristanSpeakEasy

v0.16.14

Better error handling for json package.

And included pathItems in datamodel for all v3+ (not sure how I missed this).
