bug fixes:
• corrected incorrect file encodings on many locale files.
Incorrectly encoded errors.properties files caused ST4 to crash this has also been corrected.
misc:
• Versions Bump to 12.0a1

misc:
• paste an list of all variables and in which case they can be used to all help files.
• Smarttemplate4 no longer crashes when variables are used incorrectly; an error is logged to the Error Console.
new features:
• added a new variable %sig% to allow users to put their signature where it should be placed in the template. If %sig% is not defined in the template it will be placed in the default Thunderbird location (above reply or below reply based on TB settings). 'Include Signature on Reply/Forward" must be checked in Thunderbird options for the %sig% to work as expected.
• added a new option to variable %subject% to show the subject of the message being replied to/forwarded or the subject of the current message being composed
• %tz_name% variable has been added but it is system dependent and will have limited support. Some users will see abbreviated time zone names (EST, CDT) and some will see long names (Eastern Standard Time...) and some will not have any return depending on their operating system or the mailserver of the email being replied to.

bug fixes:
• where reply header was being put above the signature when signature is placed 'above the quote'.
• automatically add line break in message compose window
• %date_tz% variable was returning the local timezone instead of the senders timezone.
misc:
locale added
• sv-SE
Thanks to BabelZilla Team!
• Versions Bump to 10.0a1
change/bug fix:
• remove the 'automatically add two line breaks' that was added in 0.7.6. This affected many users and the correct way to add line breaks at the top of your message is to include them in your template.

bug fixes:
• Fixed issue if %datelocal% variable is used for new messages
• a lot of small fixes
misc:
• changes in locale pt-BR

bug fixes:
• Some users reported subject lines not being displayed correctly. Specifically there were line breaks causing the subject to span more than one line. This could also occur with other headers but subject was the only one reported.
• corrected issue where headers longer than 4096 were being truncated.
new feature:
• An option is added in settings called "Use OS date/time format instead of Thunderbird". Some users reported that SmartTemplate 4 was not using the custom date format they had set in their operating system. This will give everyone that option if they want to use it.
misc:
• updated all helpfiles 'added recent changes'
• implemented some coding changes suggested by the Mozilla AMO review team.

changes:
• Originally the X:=sent switch would change all variables after it's use for the remainder of the template unless X:=today was used to switch them back. That behavior is now changed such that the X:=sent command only affects the line on which it is being used.
• %datelocal%, %dateshort%, %date_tz% are now affected by the X:=sent and X:=today variables.
bug fixes:
• fix CC line inner Brackets
