/*
|
||
|
|
* sync-build-version.js — make `buildNumber` mean something.
|
||
|
|
*
|
||
|
|
* package.json carried TWO build numbers: a top-level `buildNumber` that was
|
||
|
|
* dutifully bumped every release and read by absolutely nothing, and
|
||
|
|
* `build.buildVersion` — the one electron-builder writes to CFBundleVersion —
|
||
|
|
* hardcoded at "51" since 3.4.0. So the installed app reported build 51 while
|
||
|
|
* the release was build 55, and the DMG filename was the only honest clue
|
||
|
|
* anywhere. Runs as `predist`, so bumping buildNumber alone is now enough.
