+ * The newest published build, for install.sh and install.ps1.
+ *
+ * Plain text, one record per line, so both a shell script and PowerShell can
+ * parse it without a JSON library:
+ *
+ *   version 4.4.0
+ *   gui linux x86_64 4.4.0 zagan-bet-gui-4.4.0-linux-x86_64 <sha256>
+ *   gui windows x86_64 4.4.0 zagan-bet-gui-4.4.0-windows-x86_64.exe <sha256>
+ *   client ...
+ *   server ...
+ *
+ * Only the newest version is listed. The installers verify the SHA-256 they
+ * read here against the bytes they download.
