What is Fiber?

Fiber v3 has sat in release candidate for months while v2 gets security fixes only

Fiber's v2 line is receiving nothing but small security and correctness work — an HTML escaping fix in Ctx.Format, a CVE fix, defensive copying backports, limiter middleware repairs, and a backported X-Real-IP overwrite fix in the load balancer. Meanwhile v3.0.0-rc.3, the last release candidate visible here, carries all the actual feature work: native net/http and fasthttp handler support, Express-style request and response handlers, HostClient and LBClient, and HTTP 501 handling for unsupported methods.

What is Capacitor?

Capacitor 9's alpha is quietly cutting Cordova loose and moving iOS to Swift Package Manager

Capacitor is running a 9.0.0 alpha series with small, fix-dominated builds. Two structural threads run through them: Swift Package Manager support is being made to work properly, with dependency patching in plugins, prerelease handling and generation bugs fixed across consecutive alphas; and Cordova's footprint is shrinking, with Cordova.framework removed from the iOS project and the Kotlin plugin no longer added for Cordova plugins. Android work centres on SystemBars and safe-area insets.

Fiber v3 has sat in release candidate for months while v2 gets security fixes only

◆ Current state

Fiber's v2 line is receiving nothing but small security and correctness work — an HTML escaping fix in Ctx.Format, a CVE fix, defensive copying backports, limiter middleware repairs, and a backported X-Real-IP overwrite fix in the load balancer. Meanwhile v3.0.0-rc.3, the last release candidate visible here, carries all the actual feature work: native net/http and fasthttp handler support, Express-style request and response handlers, HostClient and LBClient, and HTTP 501 handling for unsupported methods.

◆ Where it's heading

The split is unusually stark. Every capability that would change how Fiber is used sits behind a v3 candidate that has not moved forward in this window, while v2 — what almost everyone actually runs — gets only fixes. The v3 feature list points at a clear thesis, making Fiber interoperable with the standard library rather than an island, but that thesis is not yet available to users on a stable release.

◆ Prediction

The entries do not show a v3 release approaching; on the visible evidence, expect v2 to keep receiving security backports and the net/http interop work to remain candidate-only until the release cadence resumes.

Capacitor 9's alpha is quietly cutting Cordova loose and moving iOS to Swift Package Manager

◆ Current state

Capacitor is running a 9.0.0 alpha series with small, fix-dominated builds. Two structural threads run through them: Swift Package Manager support is being made to work properly, with dependency patching in plugins, prerelease handling and generation bugs fixed across consecutive alphas; and Cordova's footprint is shrinking, with Cordova.framework removed from the iOS project and the Kotlin plugin no longer added for Cordova plugins. Android work centres on SystemBars and safe-area insets.

◆ Where it's heading

The direction is a Capacitor that no longer carries Cordova's build artifacts by default and that treats SPM as the iOS dependency mechanism rather than an alternative to CocoaPods. Neither is announced as a headline in these notes — both are arriving as a run of small fixes, which is how compatibility-sensitive migrations usually ship. The experimental packageOptions CLI flag and package-manager telemetry suggest the team is measuring that transition before committing to defaults.

◆ Prediction

Expect the alpha series to continue until the SPM patching fixes stop recurring, with Cordova compatibility becoming opt-in rather than assumed by the time 9.0 stabilises.
