*********************************************


2011-01-29 [M] release to Cpg Forum as v1.4 {Roland Fulde}
2011-01-29 [B] <fb:comments> at album level had been given an empty xid. Fixed. {Roland Fulde}
2011-01-29 [B] disqus_identifier (for uniquely identifying the discussion thread in disqus) has been missing the actual picture id resp. album id. Ouch. Fixed. {Roland Fulde}
2011-01-29 [B] album level output has not respected the "enabled categories" setting (it might now be overdoint it and might prevent from showing even on the album topn/lastup page, as the $CURRENT_CAT_NAME is not set there) {Roland Fulde}
2011-01-29 [B] album level output has shown on the toplevel and category topn/latstup etc pages. Fixed by not showing them there now (as no unquie album info is available there) {Roland Fulde}
2011-01-28 [B] fixed another issue with the htmlspecialchars() vs. htmlspecialchars_decode() for & < > signs in the picture title. {Roland Fulde}
2011-01-28 [M] release to Cpg Forum as v1.3 {Roland Fulde}
2011-01-28 [B] <fb:comments> now with title= attribute (it should make a nicer display on the Facebook walls then) {Roland Fulde}
2011-01-28 [M] Defaults for Facebook widgets now list a few more default attributes to play with {Roland Fulde}
2011-01-28 [A] Disqus comments according to http://docs.disqus.com/developers/universal/ {Roland Fulde}
2011-01-27 [M] release to Cpg Forum as v1.2 {Roland Fulde}
2011-01-27 [B] file_data hook had declared parameter as CURRENT_PIC_DATA and used also the global CURRENT_PIC_DATA variable -- this has prevented cooperation with other file_data hooks (possibly lightbox plugin works better now with this) - Fixed {Roland Fulde}
2011-01-27 [B] same for album and negative cat= parameter {Roland Fulde}
2011-01-27 [B] page_meta to determine the picture info not only from pid= parameter but also from pos= together with album= -- really pity that at that hook those information are not yet available from Coppermine itself. Might now work better together with various ways how to reach a picture page {Roland Fulde}
2011-01-27 [A] albums can now be shared, too, but only from the albums page, as I did not find a way how to get into the album detail information on the index pages {Roland Fulde}
2011-01-27 [B] bb_decode-and-strip-tags now correctly converted for rawurlencode and there should now be no &amp; artifacts caused by bbdecoding anymore {Roland Fulde}
2011-01-27 [O] simplify getCurrentUrl(), remove http_build_query() usage, hope this helps PHP4 compatibility {Roland Fulde}
2011-01-27 [M] release to Cpg Forum as v1.1 {Roland Fulde}
2011-01-27 [B] caption bb_decode already strips off the HTML tags -- should not htmlescape then {Roland Fulde}
2011-01-27 [B] remove href= from the fb:like -- today Facebook complains about this with "This feature is not yet enabled for your domain" (worked fine the day before) {Roland Fulde}
2011-01-27 [M] release to Cpg Forum as v1.0 {Roland Fulde}
2011-01-26 [A] optionally add the owner to the title, for "credit where credit is due" {Roland Fulde}
2011-01-26 [B] using the filename (without extension) as last resort for og:title tag. Becuase if og:title is left out, some things (in Facebook) look really ugly.
2011-01-26 [A] added the old Facebook Sharer, even though Facebook does not recommend it anymore. But it seems the only element that really posts the thumbnail to the wall/stream (see also some bloggers' bloats and various discussion boards about this issue) {Roland Fulde}
2011-01-25 [B] current URL should not be urlencoded for Facebook XFBML elements {Roland Fulde}
2011-01-25 [B] <fb:comments> must be given href= and/or url= to create proper text on walls {Roland Fulde}
2011-01-25 [A] allow the social bookmarks placement to replace the Coppermine comments function - renders Last comments (and so) useless {Roland Fulde}
2011-01-23 [B] strip bbcode from caption for OpenGraph description tag {Roland Fulde}
2011-01-23 [B] the page_meta hook of this plugin had assumed that it go no input. This has prevented proper combination with other plugins, e.g. XFeed. Now fixed in this one. As long as XFeed is not fixed in the same way, social_sharing plugin needs to be called last in the plugin chain. {Roland Fulde}
2011-01-23 [B] language selection should now be correct again {Roland Fulde}
2011-01-23 [B] FB.init() Javascript call has been missing; Facebook XFBML has not worked properly, now ok {Roland Fulde}
2011-01-23 [A] Added another positioning option, to allow placement above/under the picture (will then display even if title/caption are not shown {Roland Fulde}
2011-01-22 [A] Added Twitter. Added VZ. {Roland Fulde}
2011-01-21 [A] GUI for the configurations. {Roland Fulde}
2011-01-21 [A] Added Javascript/XFBML version of FB Like. Added FB Comment. {Roland Fulde}
2011-01-20 [A] Started development with basic features FB Like Button and OpenGraph metatags. {Roland Fulde}
