New in version 1.3.x
npm search and other non-installation related npm queries are now proxied to the registry.
New in version 1.2.x
Reworked the behavior with regards to index files, where npm_lazy would return a 500 even though it had an package.json file in it's cache once the maxRetries were exhausted if the file was considered to be up to date. The new/fixed behavior is to always fall back to the cached file.
New in version 1.x
In response to the npm outage, I've made some improvements to npm_lazy. Previously, the primary use case was to prevent multiple servers in a large deploy from causing duplicate requests.
The new version adds better caching support and resiliency to registry failures.
