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.

What is htmltools?

htmltools spends three releases walking back its own fill-layout opinions

htmltools generates the HTML that Shiny, bslib and R Markdown emit. Recent releases are dominated by one project - the fill and fillable layout system that powers bslib cards - being tuned release after release, surrounded by fixes for whatever testthat or R-devel changed underneath.

FusionAuth vs htmltools: editorial side-by-side

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.

htmltools spends three releases walking back its own fill-layout opinions

◆ Current state

htmltools generates the HTML that Shiny, bslib and R Markdown emit. Recent releases are dominated by one project - the fill and fillable layout system that powers bslib cards - being tuned release after release, surrounded by fixes for whatever testthat or R-devel changed underneath.

◆ Where it's heading

The fill work is converging rather than expanding: 0.5.6 stopped forcing overflow on fillable containers, 0.5.7 stopped forcing full width on fill items, and 0.5.8 lowered the CSS's precedence by moving it into a named cascade layer. Each step removes an opinion that broke someone's layout. The two most recent releases add nothing at all beyond test compatibility.

◆ Prediction

With the fill CSS now scoped to its own cascade layer, expect fewer layout corrections and a continued pattern of small releases driven by testthat and R-devel rather than new API.
