-Gearslip 0.3.31 brings saved places, a new music player and sixteen languages.
+Gearslip 0.3.40 is a test build for a few cars that still don't connect.
 
-## New
+If your car works on 0.3.39, you don't need this one. If you're following #18, #39 or #57, please try it and attach a log to your issue: open Gearslip, tap Logs, then Share log.
-- Save Home, Work and three places of your own under Saved places in the Car card on the phone's home screen. Say "navigate home" or "take me to work", and your map app gets the address.
-- Calls show on the car's own screens, and the car's phone button answers them.
-- A new music player: Now playing with a big cover, Browse with covers, and Up next. Beside the map, the player floats as a card; drag its edge to resize it.
-- Lyrics come from BetterLyrics, LRCLIB or KuGou, whichever has the song.
-- A Dark mode setting: black, black and colour, deep colour or grey. Black is the default.
-- Gearslip speaks Arabic, Chinese, Czech, Dutch, French, German, Italian, Japanese, Korean, Polish, Portuguese, Russian, Spanish, Swedish, Turkish and Ukrainian. Most started as machine translations, so fix your language on [Weblate](https://hosted.weblate.org/engage/gearslip/).
-- With experimental features on, car apps get the car's speed, fuel, range and compass, and cars with an instrument cluster screen get a turn card there.
-- A Manage storage screen in App info clears lyrics, voice models and old logs.
-
-## Changed
-- The nav bar floats on every screen.
-- The car's settings all sit under the Car card on the phone's home screen.
-- The Light app theme makes the phone app light too.
-- With the player beside the map, the map app's own buttons fold behind one button, so everything fits.
-- The USB audio choice is now called Through Gearslip.
-- Setup and Settings explain that some newer cars reject the built-in certificate and need your own.
 
 ## Fixed
-- Older head units that take only AAC audio no longer drop the connection when music starts.
+- A car that holds back its screen is asked for it again with the detail older cars expect. This is for the 2017 Pilot (#57) and other cars on the oldest Android Auto version.
-- Long screens such as Settings, Messages and Vehicle data scroll all the way down.
+- Music no longer carries on from the phone's speaker after you turn the car off. An app that started playing again by itself is paused a second time (#39).
-- Settings opens faster.
+- A liked song lights up the whole like button, as shuffle and repeat do. Before, only the heart filled in for apps such as Metrolist.
+
+## Testing
+- GM cars open two more channels, Bluetooth and Wi-Fi projection, and log what the car sends on them. This is to find out why the 2021 Bolt hangs up about 20 seconds in (#18). If you drive a GM car, type your phone's Bluetooth address under Settings > Connection > Phone's Bluetooth address. You'll find it in Android's Settings under About phone.

-## Which cars work
-
-Most cars work. Starting around 2020, some cars added newer security checks that reject
-the aasdk certificate, and in those cars Gearslip needs a certificate of your own. [CARS.md](CARS.md) lists the
-cars drivers have confirmed.
-
-## What Gearslip is
-
-Gearslip is an Android Auto client for the phone. It speaks the Android Auto protocol
-directly to a car head unit, over USB or wirelessly, with no Google software in the path.
-Gearslip acts as a Car App Library host: an app that ships a car interface hands Gearslip
-a template, and Gearslip renders that template natively on the car screen. Nothing is
-mirrored from the phone. For apps without a car interface, Gearslip offers a separate
-screen-sharing mode.
