Skywire Development Update — October 30, 2026

The thirtieth of October ended in the v1.3.104 release, the first with TinyGo builds of skywire published beside the Go ones. Getting there took a release job for five Linux architectures and fixes for TinyGo on 386, arm and macOS. A live review of the hypervisor UI turned into three sets of fixes, among them a visor page that kept flipping back to the previously viewed visor, and the sudph transport’s kcp-go and pfilter dependencies moved to their newest releases, with pfilter back on upstream.

Skywire: v1.3.104 and TinyGo Builds

5940 builds skywire with the TinyGo fork for every release tag and uploads the stripped binaries beside the Go assets with a -tinygo suffix. Linux amd64 and arm64 use the cores scheduler that has been on trial on a deployment server, while arm, armhf and 386 use TinyGo’s default scheduler. A failed architecture never blocks the release. On stock runners the five builds take 13 to 21 minutes, arm64 peaking at 15.2 GB of memory against a 16 GB limit, and each binary prints its version and generates a config, the 386 one natively and the arm ones under emulation. macOS does not link yet and Windows waits on a logging library fix. The same change makes a tag with a dash, such as an alpha, a prerelease that never becomes the latest release, and 5941 lets the Android build handle such tags.

The release job found the remaining TinyGo gaps. On 386 TinyGo aligns 64-bit fields to four bytes, which broke a compile time check, so 5936 puts the field first, and on arm Skycoin’s poly1305 package built both its assembly and reference files, which skycoin#3182 fixed by excluding TinyGo from the assembly files. For macOS, 5937 has the host and system stats calls return an error under TinyGo, since gopsutil reads them through cgo with SDK headers TinyGo does not ship, and 5938 and 5939 move the metrics library’s process stats to its non-cgo file under TinyGo. 5942 is the v1.3.104 release, with the changelog from 5809 to 5941.

Skywire: Hypervisor UI Review

After moving from one visor’s page to another, the info page kept switching between the two for about a minute, because the page is reused across visors and each route change subscribed to the new visor without dropping the old one. 5930 drops the previous subscription on each change and shows saved data only for the visor being viewed. Sampling the page every three seconds for 75 seconds, it showed the previous visor in 17 of 25 samples before and the right visor in all 25 after.

5934 lets the header tabs wrap instead of scrolling under the version label, stops tables from breaking words mid-word except for long keys, and makes the mobile top bar follow the theme. 5935 greys stopped apps so that red means failed, gives the two lists on the apps tab headings and matching columns, drops the commit hash that versions repeated after the tag, and renders the settings toggles as switches. Both were checked at four widths in both themes against a live hypervisor.

Skywire: Transport Dependencies and Rewards Docs

5931 moves the kcp-go fork to v5.6.84, which merges upstream’s latest changes: rate limited batches wait in the session instead of a sleeping worker, post-processing uses a shared worker pool, and closing a session releases its packet receiver. pfilter v0.0.14 kept that released receiver live, so the read loop panicked on the next packet, and the bump to v0.0.15 clears it. 5933 then switched from the pfilter fork to upstream v0.0.12, since everything the fork carried has landed there.

5943 added a guide to setting an account xpub as the reward address, from making a BIP44 wallet in the web wallet or the CLI to telling the account xpub apart from the two chain xpubs, and 5932 stopped the reward server from reading an archive folder inside its history as extra days.
