Re: Release notes for v0.19
Hum, admittedly i didn't test this area extensively yet and as i didn't see any complaints in the PR oriented thread i assumed it's all OK. Now in addition i see the PR is still pending:
https://github.com/FreeCAD/FreeCAD/pull/3062
Will the pending PR address your concerns? Where was the changed behavior discussed?

Re: Release notes for v0.19
It's a bit tricky to explain.
There are already many changes done to the expression engine by realthunder. These changes are already part of the current master code as they were part of the LinkMerge branch that made it into FreeCAD. They basically allow you to use expressions in many entry fields and with many objects, which the older expression engine didn't allow.
However, in his own development branches, realthunder developed an even more advanced expression engine that is basically a subset of Python for use inside expressions. This is a major change. Since running arbitrary Python code as an expression is a significant security risk, this has not been merged; it hasn't even been submitted to FreeCAD. It is there somewhere in realthunder's repository, but not in the master code.
Development in Expression and Spreadsheet
It's tricky. Realthunder explained it somewhere in his threads during the LinkMerge, but to find all information is going to be difficult.So, can someone summarize what has actually changed about Expressions? What's still pending or likely to be merged into 0.19?
PR #2475: Expression syntax extension
The primary issue right now is that the expressions field no longer auto-completes named Sketcher constraints. This was used by a lot of users but it doesn't currently work, so for many users this is a regression in behavior, even if internally the expression engine was "improved".
Realthunder submitted pull request #3062 to bring that behavior back, but it has been sitting in the queue for a while now. Hopefully Werner can look at it because this feature is very missed by users.
Why doesn't the auto-completer work? I don't remember the reason exactly. I don't want to misquote realthunder, but I think the idea is that the expression engine now works on all objects of the document, therefore auto-completing the names of all objects and all their properties would produce a very long list, and would be cumbersome to display. However, this is precisely addressed with #3062. As soon as that is merged, I think most users will get the old behavior back, and the new features of the expression engine will be easier to use.

Re: Release notes for v0.19
I think that now, the ExpressionEngine can handle other things as numbers: it can handle directly Placements for example (used a lot in Assembly4). Before, if you wanted to specify something in a Placement by the ExpressionEngine, you had to do it on all components (Placement.Base.x, Placement.Rotation.angle ...) and now you can handle Placements as a whole, and even make operations on them :
Code: Select all
obj_1.Placement * obj_2.Placement * obj_3.Placement ^ -1
What has (apparently and I think rightly-so) not been merged is the pseudo-python interpreter. As for the autocompletion of renamed sketcher constraints ... I use it in reverse: if I want a named variable I create it in the Variables object and use it in the ExpressionEngine of the sketcher parameter entry. I wonder how well the named sketcher constraints behaved when the toponaming hits the fan.
Re: Release notes for v0.19
Here's a new feature:
https://forum.freecadweb.org/viewtopic.php?f=27&t=44169
Should I add it to the Wiki page by myself or is this done by a maintainer (e.g. Joel)?

Re: Release notes for v0.19
You can do it yourself, just keep the general style.
Also, don't add the animated GIF, add a static image, and separately add a link to the GIF.

Re: Release notes for v0.19
Just catching up on release note maintenance. Everything noted (except the most recent feature above), has been incorporated into the release notes.
Looks like the notes have gone through a lot of changes in addition to my own work. Looking great!

Re: Release notes for v0.19
I think it's finally time to remove the excess. Following Normand's comment, with which I agree, I have removed the last section (Other modules) of the release notes. This section contained old workbenches but no updates. It basically just mentioned the same workbenches that appeared in the Release_notes_0.18 page. That's not interesting.NormandC wrote: ↑Wed Apr 10, 2019 11:39 am FreeCAD's StartPage has a list of available external workbenches.
Release notes are about what's new, not about what's working.
Cadquery has existed for years.
The wiki already has a list too. External Workbenches
We should present the new workbenches, not just rehash the old ones. All the new workbenches developed together with v0.19, and those older ones which actually had some updates (A2plus, Dodo, etc.), are already listed in the "Additional modules" section. If you want to add actual development news to one of the old workbenches (Curves, Nurbs, Silk, CadQuery, etc.) then add the information in its own sub-section under "Additional modules".
Remember that there is an improved external workbenches page where we can collect any new workbench that is developed, no matter if its included in the Addon Manager or not.

@vocx
Sure feel free to remove such stuff, if any. As you can see, this was a rather straightforward operation at the end and it didn't make much sense to worry about it at beginning.
P.S. In addition it took people and not scripts to make such release notes. Again, thanks to everybody participating and especially to you @Joel_graff, for stepping up at the beginning of the development cycle.
