v1.7.0

New Feature

• Feature/testing syntax #312 (@ysugimoto)
• Add linter rule of goto #311 (@ysugimoto)

Improvements

• Feature/custom syntax #309 (@ysugimoto)

Note

We implemented a custom syntax definition mechanism in VCL, it means we bring special syntax (statement, token, etc) only for falco rutime.
In terms of this, we specified tokenization/parser spec at https://github.com/ysugimoto/falco/blob/main/docs/parser.md.

For testing, we define grouped testing like describe keyword using custom syntax. See https://github.com/ysugimoto/falco/blob/main/docs/testing.md#grouped-testing in detail.

v1.6.0

New Feature

• Feature/implement formatter #291 (@ysugimoto)
• Feature/console subcommand #303 (@ysugimoto)
• Add enforcing and ignoring subroutine scope in linter config #296 (@ysugimoto)

Improvement

• Improve parser/ast for complex comments #302 (@ysugimoto)

Bugfixes

• Errors with concurrent simulator requests due to global interpreter state #282 (@richardmarshall)
• Fix offset/length handling in substr & utf8.substr #283 (@richardmarshall)
• Regex patterns must be literals #284 (@richardmarshall)
• Add missing backend.{name}.* variables #285 (@richardmarshall)

Imporatnt

Fastly says that an NGWAF configuration will be provided via Fastly managed dynamic snippet and probably cannot be modified.
Then Falco will raise a linting error for it, so it should be ignored by the configuration. If you're using NGWAF in your deliver service, probably this configuration is needed. see configuration.md
