The “KC s2M+MC Pro” plugin is translated to Russian, Bulgarian (myself) and Serbian (thanks, Andrijana Nikolic <firstname.lastname@example.org>). Feel free to submit translations to other languages, or to upgrade existing ones.
But this is not the only new feature - we have several. First one: When "Username" is "Email Address", can change "Username" when "Email Address" is changed (thanks, Helen Vorrath!). Means, now we ensure, that when we set username to be the user's email, it always will be, even the user (or you) change the email. Good for users - not need to remember that username is his old email.
Another update is possibility to synchronize "registration date" in "human readable" and "MC date" format. But be carefull - you must choose right one when you synchronize it with a merge tag. Whe you create the tag as "date" in MC, it is "MC format". Don't miss that, or will be unexpected behaviour...
Also there is the lists with missing members. Under the "Check for missing members" button you see messages, when some members don't exists in site or in MC list. Now the numbers there are links, which open a pop-up window with emails of missing members. This way you are able to search for them in your DB and in MC list, and can find why they are missing. So you can care better for your lists and site, as result. Thanks, Brett Goetschius, last two features I add when you leave me to support your lists. Lazy programmer is the best programmer, all you know... :-)
But biggest upgrade is the ability to synchronize existing member's info. There is new buttons for each list and for all the lists together. Means, now the "Synch it" buttons care for "missing/new members" only. But if a member stay in both WP database and in the list, "Synch it" buttons will not touch it. Instead, these new buttons will update it, means will copy the user's info from/to WP database to/from MC list, when you need that. With old versions the only way was to save the user's profile, which can not be done at bulk. Thanks, Isaac Simon and Greg Bengston, that you suggest this feature!
There is also some security updates, which also do the plugin more stable (catch more cases to synchronize), so it's good to update your version.
And, because of these updates, the list with need functions gets shorter, you are welcome to add more features there :-) How can I do your life easer?
