[Tauruslib-users] Taurus 4 preview available

[Carlos P. <cpa...@ce...>]

Hi all,

I would like to announce that we uploaded a preview of the development 
of taurus v 4.0.0 on which we have been working at ALBA.

You can try it by checking out the "taurus4-preview" branch from the 
canonical git repo.

The main changes introduced in Taurus4 are those documented in TEP3 and 
TEP14, plus some widget adaptations. The most visible changes for the 
user are:

* Units support: numerical values types are pint Quantities (instead 
  of int or float)
* The core is control-system agnostic (tango dependency is now optional)
* Much more powerful and robust eval scheme
* Simplified API for creating new schemes

Note that this introduced some unavoidable API backward 
incompatibilities (i.e. some code created for taurus 3.x may need 
modifications to work with 4.x), but we have done a huge effort to 
minimize this by providing a backwards compatibility API that will 
correctly handle "3.x-style" code and issue recommendations of "new-
style" alternatives whenever it is possible.

Apart from the above-mentioned incompatibilities, note that this is a 
"preview" (i.e. alpha stage) and it contains some bugs that need to be 
fixed prior to the release. You can find the list of taurus4 release-
critical bugs here:

https://sourceforge.net/p/tauruslib/tickets/milestone/taurus4/

We would love to get the feedback of the community. Please try taurus 4 
and give feedback. Bugs can be reported on the usual tracker (please 
specify if they are taurus4-specific)

Cheers,

Carlos (on behalf of ALBA's Taurus Developers)

PS: Regarding the plans for the official release of taurus4 and the 
support for taurus 3.x after that, I will write the details in another 
email soon.
