+ * Version codes are quite sensitive, because there is a mix between bundle and APKs.
  * Max versionCode allowed by the PlayStore (for information):
  * 2_100_000_000
- * Current version code of EAx on the PlayStore, for the first uploaded beta (we cannot go below):
- * ----1_001_000
- * Current version code of EAx on the nightly:
- * ----1_001_000
- * Current version of Element Android (at some point EAx will replace this app) (v1.6.3)
- * ----40_106_03a where a stands for the architecture: 1, 2, 3, 4 and 0 for the universal APK
- * Current version of EAx distributed with Firebase app distribution:
- * ----1_002_000
- * Latest version of EAx distributed with Firebase app distribution (downgrading, so that's a problem)
- * -------10_200
- * Version when running the current debug build
- * -------10_200
  *
- * So adding 4_000_000 to the current version Code computed here should be fine, and since the versionCode
- * is multiplied by 10 in app/build.gradle.kts#L168:
+ * Also note that the versionCode is multiplied by 10 in app/build.gradle.kts#L168:
  * ```
  * output.versionCode.set((output.versionCode.get() ?: 0) * 10 + abiCode))
  * ```
- * we will have:
- * Release version:
- * ---40_001_020
- * Nightly version:
- * ---40_001_020
- * Debug version:
- * ---40_010_200
+ * We are using a CalVer-like approach to version the application. The version code is calculated as follows:
+ * - 4 digits for the year
+ * - 2 digits for the month
+ * - 2 digits for the release number
+ * So for instance, the first release of Jan 2025 will have the version code: 20250100 (20_250_100)
