[Fedik]

to install it need to actived compatibility plugin

Does it work when you enable this plugin?

[HLeithner]

that doesn't look like a bug, as @Fedik says I installed the component with activated plugin and no problem on installation. @micker can you please confirm

[micker]

that i say if i use beta 1 that works without plugin compatibility if i use beta 2 need to actived it and that working BUT compatibility plugin isn't actived by default !

[HLeithner]

ok then this is not a bug, thanks for your report. b/c plugin is for old extensions which doesn't use the latest standards, it's not decided yet if the plugin is on or off for new installations, it's on for updates installations by default.

[micker]

but where we can found any reference to this change ??

[HLeithner]

All things that can break (which shouldn't be many) are listed in the migration documentation: https://manual.joomla.org/migrations/44-50/

The b/c plugin is documented here: https://manual.joomla.org/migrations/44-50/compat-plugin

[micker]

ok thanks
