Add-on 'Tvheadend HTSP Client' is using an incompatible API version

I compiled clean XBMC and PVR plugins from git (git reset --hard; git clean -xfd; git pull; ./bootstrap; ./configure; make), removed pvr.hts from addons dir, installed PVR HTS plugin from ZIP. But I can't activate new PVR plugin, I receive error message:
ERROR: PVR - Add-on 'Tvheadend HTSP Client' is using an incompatible API version. XBMC minimum API version = '1.6.0', add-on API version '1.5.0'
See log: http://pastebin.com/7fzTrz64 (Line 501).
XBMC: commit 22795bcfc49b8dd0e7a66e8d3c352ccca3949511 Mon Nov 19 12:13:49 2012 -0800
PVR: commit e7c88eda0cd124ab215e4796c8484b986156071f Sun Nov 18 03:21:25 2012 -0800
What's wrong?
Edit: When I used XBMC ALPHA7 PVR plugin was working OK.
