>>>>>>> Since the loss of the Basic view is too much for a point release, I

>>>>>>> planned for H6.
>>>>>>>
>>>>>>> IIRC, we need to still talk about what this would look like from a
>>>>>>> repository stand-point since we would now need maintain 2 stable
>>>>>>> branches, along with master. Horde 6 was planned to be released after
>>>>>>> we split the repository into individual repos for each component. I'm
>>>>>>> torn as to how I feel about this. One the one hand it gets new
>>>>>>> features out quicker, which absolutely has to happen, but it means
>>>>>>> delaying a bunch of BC breaking things and slowing future progress.

>>>>>>>
>>>>>>> Jan and I need to go over this and see exactly what needs to be done

>>>>>>> our community supporters.
>>>>>>>
>>>>>>>> Additionally, PHP is moving more and more towards 7.0, so an official
>>>>>>>> support of the Horde project for PHP7 would be nice. I read in the
>>>>>>>> list that
>>>>>>>> PHP7 should basically work, also forcing packages to PHP7 is still

>>>>>>>> I will test this out soon.
>>>>>>>
>>>>>>> I have an install running just this locally and, at least for my
>>>>>>> day-to-day use cases, works well - despite the WARNINGS that creep up
>>>>>>> in the logs.
>>>>>>>
>>>>>>>> What is required in detail to bring official PHP 7 support to all
>>>>>>>> packages to close this topic?
>>>>>>>
>>>>>>> I think while we can do what we can to increase PHP 7 support for the
>>>>>>> current release applications, we can never officially mark them as
>>>>>>> PHP7 - this will have to wait until H6.
>>>>>>>
>>>>>>> There are still some external libraries that we depend on that are not
>>>>>>> PHP 7 compatible. We will need to either find replacements for those
>>>>>>> libraries, or fork/refactor them under the Horde banner. This could be
>>>>>>> a non-trivial amount of work (not sure as I haven't personally looked
>>>>>>> at the code for these yet). The good news is that I believe we only
>>>>>>> have a few of these situations, like Text_Wiki in Wicked. We could
>>>>>>> always hold back the releases of these applications if needed in order
>>>>>>> to get the rest of the main groupware applications out.
>>>>>>>
>>>>>>>> As a last step: is EAS 16.0 finally implemented? What is a blocker to
>>>>>>>> release it (maybe even in the 5.2 series?)
>>>>>>>
>>>>>>> EAS 16.0 has been implemented for some time now, but requires both a
>>>>>>> client that supports it and our current git master code to make use of
>>>>>>> it. The current stable ActiveSync library supports it, but the
>>>>>>> 5.2 series of applications will not since it required significant
>>>>>>> additions/changes to the various application APIs.
>>>>>>>
>>>>>>>
>>>>>>>> What would it cost to implement EAS 16.1 [1] (including release as
>>>>>>>> official packages!)?
>>>>>>>
>>>>>>> I haven't looked at this, other than reading the generic description
>>>>>>> of things it's supposed to add. IIRC, it adds support for
>>>>>>> renegotiating meetings times and more atomic data wipes (so you could
>>>>>>> wipe just the exchange data and not the entire device, for example).
>>>>>>> For the former, this would mean that in addition to the ActiveSync
>>>>>>> changes needed, we would need to add support to Kronolith for iTip
>>>>>>> COUNTER/DECLINECOUNTER and SEQUENCE support [1]. Of course would also
>>>>>>> need a client that actually supports this to test.
>>>>>>>
>>>>>>> If we can get at least support in Kronolith and our iCalendar code for
>>>>>>> COUNTER/DECLINE etc...before Horde 6 then we could conceivably get
>>>>>>> this functionality in Horde 6.0 when the ActiveSync side of it is
>>>>>>> done. Otherwise, it would have to wait for 6.1/7.0.
>>>>>>>
>>>>>>>> Thanks again for all your input into the project!

BTW wie should then also fix some other errores which will be very  
likely a show stopper in PHP 7.1 or above:
