It did not check one it was merely *pointed* at — through `CORDIAL_APK`, the APK you choose in Settings, an engine directory beside it, or Sober's package directory. Those went into the same store the Version page lists, sitting beside builds that had been checked, with nothing to tell them apart. They are checked now, once, against Roblox's signing certificate. The fingerprint is recorded next to the extracted engine, so later launches read it back rather than digesting a hundred-megabyte archive again. A refusal says which kind of failure it was, because a tampered archive and an intact one that simply is not Roblox's are different problems. **What changes for you:** if you point Cordial at an APK that did not come from Roblox, it now refuses rather than running it. `cordial-run --apk` is deliberately unchanged — naming a file on your own command line is the documented loader switch, and it stays one. Reported by **@kanqz**. ## The package repositories follow releases again If you installed from the apt, dnf or pacman repositories, you have been receiving **every commit to main**. The publishers fired on any successful build, and that workflow runs on every push, so `apt upgrade` could hand you an unreleased tree that no notes had been written for. They now publish only from a tag. This release is the first one to go out that way. The Flatpak remote is unchanged and still follows main. Moving it needs a settings change on the Pages environment rather than a change to the workflow, so it is not in this release. ## Every binary says what it is and under what licence `cordial --help`, `cordial-run`'s usage text and the diagnostics block now carry the version, the licence and the project URL, so a stray binary can be identified with `strings` alone. Nothing reads it back and removing it breaks nothing — Cordial does not ship integrity marks, and anything that behaved differently when the string was missing would be one. ## What is still broken **Nothing in this release fixes a crash.** It is a packaging and verification release, and the faults people are hitting are still here: * **The second launch fails for some people**, with `Can't initialize the TaskScheduler before flags have been loaded`. Clearing the cache buys exactly one more working run. This is the most-reported problem in the tracker and is being worked on now — [#44](https://github.com/luohoa97/cordial/issues/44), [#28](https://github.com/luohoa97/cordial/issues/28). * **Fullscreen freezes the client, and leaving fullscreen crashes it** — [#39](https://github.com/luohoa97/cordial/issues/39). * **No window appears on COSMIC, KWin or wlroots compositors** — [#38](https://github.com/luohoa97/cordial/issues/38). Mutter and X11 are unaffected. * **A touchscreen crashes the client on the first touch** — [#36](https://github.com/luohoa97/cordial/issues/36). * **On X11 the camera can spin a full 180 degrees**, and inputs can stick for a few seconds — [#41](https://github.com/luohoa97/cordial/issues/41). * **Join in a game's Servers list does nothing** — [#40](https://github.com/luohoa97/cordial/issues/40). Play on the home page and the game page still work. If you hit any of these, the most useful thing you can send is **Settings → Report a Problem → Copy diagnostics** together with the *end* of the log rather than the beginning — for a crash, the last forty lines are the half that contains the answer. Everything listed as broken in [0.15.0](/releases/v0.15.0) still is. This documentation is built and hosted on [Mintlify](https://mintlify.com), a developer documentation platform.
