[O] Agenda Tag filtering - has the behaviour changed?

[Bernt Hansen]

Hi,

I am a long-time user of org-mode and am currently using the maintenance
release 8.3.1

I noticed that in the agenda the '//' key to filter by tag now adds tags
when used multiple times.  This breaks my normal workflow for quickly
filtering by a specific tag.

In the past I would do:

/ P to filter items for PRODUCTION then
/ D to filter items by DEV

But now the behaviour is

/ P to filter items by PRODUCTION
/ D adds DEV to filtering by PRODUCTION+DEV which returns no items.

Now I have to do // to clear the tag list between filters.

Is this intended behaviour and did I miss the NEWS update on this?

Thanks,
Bernt
