+ <dt>v2b </dt><dl>Fixed in the pertag-tab patch the support for per-tag default layout specification. No change in the tab only patch.</dl>
+ <dt>v2a </dt><dl>Typo corrected in the man page. For the combined pertag-tab patch, specification of a default layout per-tag layout was added in the config.h configuration file, but it was not taken into account properly. The versin v2b fixed this issue.</dl>
