[4.1.0] - 2021-04-15

Added

  • Types are now exported as yaml.types.XXX.
  • Every type now has options property with original arguments kept as they were (see yaml.types.int.options as an example).

Changed

[4.0.0] - 2021-01-03

Changed

  • Check migration guide to see details for all breaking changes.
  • Breaking: "unsafe" tags !!js/function, !!js/regexp, !!js/undefined are moved to js-yaml-js-types package.
  • Breaking: removed safe* functions. Use load, loadAll, dump instead which are all now safe by default.
  • yaml.DEFAULT_SAFE_SCHEMA and yaml.DEFAULT_FULL_SCHEMA are removed, use yaml.DEFAULT_SCHEMA instead.
  • yaml.Schema.create(schema, tags) is removed, use schema.extend(tags) instead.
  • !!binary now always mapped to Uint8Array on load.
  • Reduced nesting of /lib folder.
  • Parse numbers according to YAML 1.2 instead of YAML 1.1 (01234 is now decimal, 0o1234 is octal, 1:23 is parsed as string instead of base60).
  • dump() no longer quotes :, [, ], (, ) except when necessary, #470, #557.
  • Line and column in exceptions are now formatted as (X:Y) instead of at line X, column Y (also present in compact format), #332.

  • dump() now serializes undefined as null in collections and removes keys with undefined in mappings, #571.
  • dump() with skipInvalid=true now serializes invalid items in collections as null.
  • Custom tags starting with ! are now dumped as !tag instead of !<!tag>, #576.
  • Custom tags starting with tag:yaml.org,2002: are now shorthanded using !!, #258.

Added

  • Added .mjs (es modules) support.
  • Added quotingType and forceQuotes options for dumper to configure string literal style, #290, #529.

It looks like you are reviewing a Dependabot upgrade PR! 🛠️
That’s great! Keeping our packages up to date to fix security issues in our stack is super important. Team Application Security wants to help make this process as easy and low friction as possible while still moving at pace.

We aim to merge Dependabot PRs within the below timeframes. The objectives are based on the severity of the security vulnerability we are mitigating with the upgrade:

Severity Target Merge (days)
CRITICAL 7 days
HIGH 14 days
MEDIUM 30 days
LOW 90 days

🎯 Target merge date for this PR: 17/02/2026 🎯

FAQ

What if we aren’t vulnerable to this particular CVE? Do we still have to upgrade the package? It’s still a good idea to upgrade the package if we can. With new code patterns and paths being introduced every day, we have no guarantee that we won’t later make ourselves vulnerable. Keeping packages up to date as a matter of due course is also good hygiene.
What if we’re not vulnerable and upgrading is going to be a lot of work? In these cases it’s a good idea to list out the steps you took to confirm we are not vulnerable in this PR. The PR can then be closed and the corresponding Dependabot Alert should be dismissed with the triage steps included as a comment. Please get in touch with Team Application Security via #ask-security before dismissing any CRITICAL alerts.
This is a major version upgrade that requires substantial code refactoring. What should I do? If the upgrade requires substantial refactoring then it is possible that we will miss the objectives we have outlined above. In these cases, you should add the dependabot-refactor-required label to this PR and ping #ask-security for further advice.
