Stable release 0.8.9 — Endless Sky Steam update #846160

Release 0.8.9 of Endless Sky is now available. After a week in "beta" it is now the default version on Steam. This update includes many small bug fixes, plus some new features, including: All sound effects have been redone, with better volume balance. You can jettison cargo in the info panel, to make room for plunder. The map view can be zoomed in and out. "Keys" are shown explaining the colors used in all the map panels. Many new ship names, hail messages, and commodity names have been added. See the changelog for a much more detailed list of changes. There will probably be one more "stable" bug fix release after this, and then I'll switch gears to making larger changes to the code to begin making progress on my goals for the eventual 1.0.0 release. Special thanks to everyone who reported bugs and to the GitHub users who contributed changes to this new release: guillochon, Pointedstick,...
