Confusion where to download the apps

[xaur]

Announcement team got confused about what is the recommended entry point link to download the standalone DEX app. I think new users coming to our sites will be equally confused. The options are and tradeoffs are:

• https://github.com/decred/dcrdex/releases/tag/v0.6.3

  • Pro: Release notes and downloads on the same page
  • Con: No signatures
  • Con: Fewer OS choices
  • Con: Hard to decide if Windows users need that -tray- version

• https://github.com/decred/decred-binaries/releases/tag/v1.8.1

  • Pro: Signed builds
  • Pro: More OS choices
  • Con: No release notes for the DEX
  • Con: Unclear if Windows system tray integration is enabled

• https://decred.org/wallet/

  • Pro: Pretty and short link (people are scared of github links!)
  • Pro: If we announce this it routes people through decred.org and people see all wallet choices
  • Con: The DEX tile only links to the first option, the decred-binaries option is invisible

• https://dex.decred.org/

  • Pro: Pretty and short link
  • Pro: Has useful info (intro, setup tips, supported assets), all with sleek design
  • Con: The download choices are somewhat hard to navigate (https://github.com/decred/dexweb/issues/20 , https://github.com/decred/dexweb/issues/41)
  • Con: Decrediton links and asset list are outdated now

I may have missed something but clearly this needs to be streamlined. First let's pick which are the recommended binaries (built by Decred Release or by DEX devs), second let's choose the canonical entry point, third let's make it easy to follow.

One attempt to untangle this from the bottom up and eliminate unnecessary choices for end users.

Which set of binaries?

• Is there really a need to have two sets of binaries to choose from? If not, continue
• Use binaries from v1.8.1 release for their benefits: more OS choices, tray and non-tray exe-s bundled in one download, sigs, build automation, building blocks for reproducible builds

Where to place the binaries?

• dcrdex releases is the best place
• Replace dexc binaries, hashes and sigs in DEX v0.6.3 release with ones from v1.8.1 release
• Remove dexc binaries from v1.8.1 to avoid confusion, edit v1.8.1 release page to link to dcrdex release
• Result: All wins in one place (bins and relnotes together, single set of bins, all OS choices, signed by Decred Release key, choices and confusion reduced)

What is the main link to use in announcements

• dex.decred.org is the best: it is shorter and easier to remember and share than the long github links, also it presents the product better than decred.org
• Optimize its onboarding properties, fix some issues
• Change decred.org/wallet to link dex.decred.org
