CHANGELOG.txt

@@ -25,6 +25,7 @@ Changes / Improvements / Optimisations:
 - DietPi-Software | Koel: The latest upstream release will be pulled automatically now, v4.2.2 at date of writing. Dependencies have been updated accordingly, e.g. latest Koel supports latest Node.js v13.5.0.
 - DietPi-Software | NoMachine: Updated to latest version 6.9.2 and switched to URL with no version string, which allows us to update downloads on-the-fly without code changes. Download URLs from official website have been simplified and follow some logic, but there are no "latest" URLs available and older versions are not kept, hence we must go on hosting those packages on dietpi.com.
 - DietPi-Software | Allo web UI: Updated to version 13.1, which mostly fixes some compatibility issues with DietPi v6.27 and Debian Buster systems. For details, see: /var/www/allo/CHANGELOG.txt
+- DietPi-Software | phpMyAdmin: The APT package install has been replaced by an upstream archive download. This allows us to ship the most current version on all distro versions and avoids incompatibility due to PHP meta packages being pulled as dependencies by the APT package. Install on Buster and Bullseye is possible now by this and incompatibility with concurrent ownCloud and phpBB has been resolved. On Stretch this resolves an issue due to new PHP7.4 being pulled by "php" meta package from Ondrejs repo. Many thanks to @symlagom for reporting this issue: https://github.com/MichaIng/DietPi/issues/3284
 
 Bug Fixes:
 - DietPi-PREP | Resolved an issue, where in rare cases a wrong $PATH variable could break command calls. Many thanks to @dtm2001 for reporting this issue: https://github.com/MichaIng/DietPi/issues/3206
