According to this blogpost on openandromaps.org (https://www.openandromaps.org/locus-direct-install-link-fuer-mehrsprachige-v4-karten), OAM plans to stop producing v3 vector maps as of mid 2019.

Fortunately, Locus is able to deal with v4 maps (provided as "ML" - maps from OAM) using the standard mapsforge v4 library (without the Locus-specific enhancements like automatic map loading). Btw.: what other enhancements does the Locus v3 implementation offer compared to the default v4 implementation? I remember something like rendering speed optimizations...what else?

The other thing is themes...currently I use some really nice Locus-specific themes I don't want to miss. I'd like to start a list of OAM-compatible themes and the availability of v4-versions. I try to update the list when I or others find out more details...

HiLoin development, called 'active RT'
Tiramisuyes
Totmyes
outdoorX (outdoor/desert/navigation)outdoorV4 and desertV4 available, will be further developed

Locus enhancement for v3 includes
- controllable intelligent scaling (resolution-aware) of text, symbols on zooming
- proper treatment of dotted or dashed lines on zooming, so visual spacing stays constant
- fancy labels for roads etc
- ability to display contour lines as smoothed curves
- ability to render elevation text of contour lines "looking up the hill" (switch off rotation of pathtext for "normal" viewing)
- uppercase transformation of text
- dx shift of path text
- dy shift of pathtext understands if text has been rotated for "normal" viewing
- speed enhancements

Someone can probably add to this list which I've just done from the top of my head

Well, some of that lies in Locus and can be replicated by Menion once he gets serious to move ahead with V4 (incl. MF POI DBs - address DB would stay Locus "private" in any case, I suppose).
Some other useful stuff from your list Menion should contribute to Mapsforge base, which has been a kickstart for Asamm initially ...

Thanks @john_percy for your feedback on the special Locus enhancements!
There is a main thread for mapsforge v4+ development now...but I'd like to keep this thread open because it's about themes and I think not all v3 themes (especially the themes which use locus-specific enhancements) will work with v4 library.

I guess we have to wait for menions actions in the next months and try themes again when there are new (beta) versions available...

Hello,
I also tried several times V4 maps from OpenAndroMaps (the ML version). And I stopped doing so, because some parts of the maps stay white depending on the zoom level.

I just made some snapshots with Locus Map Pro 3.37.2 on a Samsung Galaxy S5 mini.

Here the map Alps Ost in the ML (V4) version with the theme Elevate for bicycles:


Here the map Alps Ost in the old (V3) version with the theme Elevate LE for bicycles:


I only get the problem with with tiles with V4 maps. I tried different themes and always get the same white tiles. I got the problem with all ML maps that I tried.

Hello jerome,
if possible, leave it be for a while. The whole system around maps will completely change probably in the end of May (based on this topic: https://forum.locusmap.eu/index.php?topic=6471.msg54300#msg54300 ).
So a) try and check what we discuss in the mentioned topic or just b) wait till new version with these changes. Thanks.

Is there a definitive guide to the usage of these tags anywhere?

The best thing is still this:
https://github.com/mapsforge/mapsforge/blob/master/docs/Rendertheme.md
That's a reason why I made the table, to have at least a complete overview. Of course one can add a lot to it, but it's a start.

Nice, with the release of TOTM v4, there is a v4 version for all the themes in my list now! Thank you to all theme developers for migrating to v4!

Are there other themes which are not converted to v4 yet?
