What is censusapi?

censusapi made API keys optional in 2025, then the Census Bureau made them mandatory.

censusapi is a general client for the US Census Bureau's APIs, letting users query any endpoint rather than a curated subset. Its release history is sparse — six entries spanning 2017 to 2026 — and driven almost entirely by upstream change. The May 2026 release exists because the Bureau began requiring an API key for both data and metadata retrieval, which reverses the headline feature of the previous release fourteen months earlier.

What is FusionAuth?

FusionAuth's feed publishes version numbers; whether they carry news is a coin flip.

FusionAuth releases every four to eight weeks, but the changelog entries are inconsistent: three of the last six carry nothing but an upgrade-guide link, while the ones that do have notes describe substantial standards and security work. The last documented release, 1.67.0, added RFC 8707 resource scoping so tokens issued by OAuth endpoints can be bound to specific resources. Before it, two consecutive releases tightened API key requirements — 1.65.0 for installation-wide endpoints, 1.66.0 extending the same rule to webhooks it had missed.

censusapi made API keys optional in 2025, then the Census Bureau made them mandatory.

◆ Current state

censusapi is a general client for the US Census Bureau's APIs, letting users query any endpoint rather than a curated subset. Its release history is sparse — six entries spanning 2017 to 2026 — and driven almost entirely by upstream change. The May 2026 release exists because the Bureau began requiring an API key for both data and metadata retrieval, which reverses the headline feature of the previous release fourteen months earlier.

◆ Where it's heading

The package's direction is set by the Census Bureau, not its maintainer. The 0.9.0 release invested in making keys optional and added helper functions for detecting and retrieving stored keys; 0.10.0 undoes the optionality while keeping the helpers, which now matter more than before. Between those upstream shocks the maintenance pattern is consistent: better type inference for returned columns, cleaner column naming, and converting the Bureau's malformed 'N/A' and 'NULL' strings into real NA values.

◆ Prediction

Expect the next release to respond to another Bureau-side change — endpoint deprecations or new vintages — rather than to a planned feature. The entries contain no self-directed roadmap.

F2.5

FusionAuth's feed publishes version numbers; whether they carry news is a coin flip.

◆ Current state

FusionAuth releases every four to eight weeks, but the changelog entries are inconsistent: three of the last six carry nothing but an upgrade-guide link, while the ones that do have notes describe substantial standards and security work. The last documented release, 1.67.0, added RFC 8707 resource scoping so tokens issued by OAuth endpoints can be bound to specific resources. Before it, two consecutive releases tightened API key requirements — 1.65.0 for installation-wide endpoints, 1.66.0 extending the same rule to webhooks it had missed.

◆ Where it's heading

Where the notes are readable, the direction is standards conformance and closing security defaults that were too permissive, accepting breaking changes to do it. FusionAuth has been willing to make an enabled identity provider's linking strategy immutable and to require global API keys where tenant keys used to work — changes that break running deployments in exchange for a tighter default. What cannot be read from this feed is where the last two releases fit, because they shipped without notes.

◆ Prediction

The pattern of hardening endpoint-by-endpoint suggests further scope narrowing wherever tenant-level keys still reach installation-level effects. Any read on 1.68.0 and 1.69.0 would be guesswork — the entries carry no content.
