There seems to be a change in behaviour of xfce4-power-manager from 14.1 to current.

In 14.1, xfce4-power-manager was showing an icon reflecting the battery status. In -current, there is just a simple power cable symbol irrespective of power supply is plugged in or not, while xfce4-power-manager shows battery status in its settings dialogue.

See attached pictures "xfc4-power-manager-no-battery-status", "xfce4-power-manager-right-click", "xfce4-power-manager-settings-*".

While I can work around this in Xfce by adding yet another icon (see xfce4-power-manager-workaround"), I am in trouble on another window manager (e.g. fluxbox).

Is this a bug or new feature? Or does it require additional configuration? Running plain slackware-current as of Fri Jun 24 23:37:19 UTC 2016, no further software installed.

I was unaware of this feature, but I previously used xfce4-battery-plugin without power-manager on 14.1 netbook and it worked fine.

Was this an upgrade?

Hm.... from the powermanager-plugin changelog:
Could it be that this feature is no longer supported ?

BTW: Thx to elcore. I didn't know that the battery-plugin is alive again. Have not tested it but will do so shortly.

My -current has been freshly installed around mid of December last year. Since then, I am following -current by upgrading to the latest packages.

I am on current as well but do not have this wrong-icon problem. Do you perhaps have the 'Show system tray icon' ticked in the section 'appearance' of the 'general' tab of the 'preferences'-dialog for the power-manager-applet? When set, that shows one icon and does not change to the battery you expect when unplugging from the mains. This is unset in my case...

I was curious since I also don't have that problem when in XFCE so I tried checking / unchecking and pulling / inserting the charger to find there was no effect at all

Yup, 'Show system tray icon' is ticked. In 14.1, xfpm (xfce4-power-manager) does display the battery status w/o requiring an additional app like power manager plugin. In -current, xfpm only displays one static icon.

This causes troubles with window managers like fluxbox: in 14.1, only xfpm was required to take care of power management and displaying battery status. What would be your suggestion for this scenario in -current?

I would suggest to untick that box on the xfce power-manager and see how that pans out on fluxbox. On Xfce the plugin-icon behaves as expected and you can do without the systray one. I dunno whether on fluxbox you can use the plugin (and can do without the systray). If you can only work with the systray on fluxbox this icon-issue might be an aspect that need an upstream change/patch; hard to tell whether this is specific for Slackware.

Fluxbox's toolbar/tray displays xfpm icon, if 'Show system tray icon' is checked, otherwise it does not (see screenshots).

To summarize:

• between 14.1 and -current, the representation of xfpm did change from displaying the current battery status to just a static icon

• on Xfce, there is the workaround of hiding xfpm's featureless icon by unchecking 'Show system tray icon' and adding another app (power-manager-plugin) to the taskbar

• on other window managers, like fluxbox, that could use xfpm's functionality, especially the changing icons to display the battery and charging status in 14.1, this is not possible anymore with -current's version of xfpm

As a temporary fix I'd suggest xfce4-panel in fluxbox session instead of toolbox, so that you can use the workaround you've mentioned.
Is a bit heavy, but has more features, and it can look like flux toolbox if you configure it that way.
There's a wm check, but works with any wm, I just add into ~/.fluxbox/startup
