Clyton Revision History

Version 9.0 (April 24th, 2013)
* Major interface improvements.  Improved all skins.
* Added support for sub-folders.  This is great for organizing your archived email.
* In fields that support unicode:  added support for keyboards that generate unicode characters.  Added support for IONICODE Keyboard Enhancer software.  Fixed: while typing a character code with the Alt+Plus+Numpad method, pressing F will no longer open the File menu.
* Added full support for editing 16-bit unicode characters in the headers and Text Body of the Mass Mail Preview Window.
* Added the "Trust All" icon to the right end of the email contents bar.  This makes it easier to allow an email to show images.
* Added the "Mailbox", "Folder", and "Message" menus.  Although redundant, users who are familiar with other email clients may prefer them to using buttons or right clicking.
* Compose: when there is no Text Body, one will be synthesized automatically from the HTML Body.  Even though the Text Body is only displayed by email clients that don't support HTML, and these are exceedingly rare, we encountered a spam filter that penalized emails that lack a Text Body.  Hence, this will improve deliverability.
* Added to the Attachment Viewer support for text files that are in UTF-8.
* Added the "Insert Quotation" tool to the HTML editor.
* The "Trash Day" tool now allows you to exclude certain Mailboxes from the operation.
* Added the "Receive One" submenu to the Client menu.  This allows you to receive email for a single Mailbox of your choosing.

* Compose: the "Add Recipient" tool now supports unicode characters.
* Numerous improvements to the conversion process from HTML to plain text.

* The "Import Messages" tool now imports all sub-folders of the chosen folder.
* Added the "Confirm discard" and "Discard after single send" options to the Mass Mail Preview Window.
* The Unicode Character Map now uses narrow cells if neither the hex nor decimal code is displayed.  Also, the Page Up/Down keys are now supported.
* If an IP address on the email's route has already been blacklisted, it will no longer incur another spam penalty if the same IP address appears in a hyperlink.
* Smiley faces are now the same height as a line of text.
* Added the mime_content() G-Merge function, which is useful for searching an incoming email for a text substring.

* Added support for emails that use the "CP775" character set.
* The "Raw HTML" tab now obeys the HTML character set.

* Added a chapter on the "Import Contacts" tool to the help file.  Improved the chapter on the Incoming Script.
* The "Refresh Table" tool will no longer cause the email color codes to be lost.

* The "Import Contacts: Field Map" window will now report an error if the same field is chosen more than once.
* When moving an email from the Sent folder to any other folder, the content of the Received column was blank.  Now, the date from the Created column is copied there, so that sorting will work correctly.
* The number of contacts imported successfully is now reported.
* After product activation, the user is now given the opportunity to download and install a free upgrade to the latest version.
* After clicking any checkbox, input focus is now given to the next editbox, if appropriate.
* Added the http_post(), hash_md5(), hash_sha256() G-Merge functions.
* Mass Mail tool: the Spell Checker for the HTML editor's Raw tab will now ignore G-Merge statements.
* The "Empty Folder" tool now reports the number of emails that it is about to delete.
* The escape key will now close the HTML editor's context menu.
* Moved the "Import Messages" tool from the Tools menu to the File menu.

* Fixed: hidden controls were sometimes part of the tab order.
* Fixed: the HTML validator tool was broken after w3.org began requiring a User-Agent header.

Version 8.0 (September 4th, 2012)
* Added to the Compose window support for editing the headers and text body in 16 bit unicode characters.  Previously only 8 bit ASCII characters were supported.  Removed the "Character Set" setting from the Compose window since it is no longer needed.
* Numerous improvements to the Attachment Viewer.  Added support for displaying PDF files.  Added support for HTML and text files that are in unicode, provided they contain the "byte order mark".  Added a "View Source" tool to the right click menu for an HTML attachment.  Fixed scrolling issues and a memory leak.
* Numerous interface improvements.  Improved the Default skin.
* Added the ability to resize an image attachment on the Compose Window.
* Added to the Compose window's Add Recipient tool the ability to search for a contact.
* The HTML editor will now canonicalize character codes 128-255 to help ensure that they appear properly in the receiving email client.
* Replies will now preserve the inline style of the original email's <BODY> tag.
* Replies are now much better about displaying unicode characters in the quoted email.
* Forwards will now display unicode characters instead of MIME encoding for the original From, To, and Subject.  However, you must load the default "Forward" template for this to work.  This utilizes the new header_to_html() G-Merge function.
* Added the "Insert Groupbox" tool to the HTML editor.
* Added the ability to resend an outgoing email.  Right click on an email in the Sent folder's Messages Table, and choose "Resend".
* Added the "Colorize Dequarantined Messages" option to the Spam branch.
* Added to the Email Viewer the ability to select and copy part of a unicode header.
* During the compression phase of the Export Settings tool, a progress window now appears, and the operation can be aborted.
* Added a menu bar to the Mass Mail tool's Preview Window.  Also, it will now display headers in the character set selected on the Compose Window.
* When an email specifies the US-ASCII character set, WINDOWS-1252 is now used instead.  This ensures that non-ASCII characters will appear correctly instead of as squares.
* The default templates no longer specify the font in the <BODY> tag, but inside a <DIV> instead.  This way, when another email client replies to an email sent by Clyton, the reply is more likely to accurately duplicate the font of the original email.
* Significant improvement to how fast curses are detected during spam testing.
* Numerous improvements to the Unicode Character Map.
* The Outbox and Sent folders will now display the BCC: header.
* Added the ability to change the email address to which phishing attacks are reported by the Report Phishing tool.
* Redesigned the Reply and Forward templates.

* Added the trusted() G-Merge function for the Incoming Script.  It returns true if the received email's sender is in the Trusted Addresses List.
* When viewing a received email, if it has no text body, the auto-generated text body on the "Text" tab will now display unicode characters properly.
* The birthday/anniversary reminder now mentions the contact's email address and phone numbers.
* Added an "Open Folder" button to the Export Summary window.  This will open the folder that contains the export file in Windows Explorer.
* Added the "Lookup" button to the SMTP Server Name mailbox property.
* When the "Add Curse" tool is launched from an email body's context menu, it will now allow the user to edit the curse first before adding it.
* Added the "Troubleshoot Curses" tool to the context menu for the Curses list.  This will report any case where a curse is a substring of another curse.
* Cleaned up the list of curses.  Unless you have been adding many of your own curses, we recommend going to the Curses List, right clicking on it, and choosing "Load Default Curses".
* Added new G-Merge date format codes that use the computer's regional settings.  "~" specifies the regional date.  "@" specifies the regional time.  "~@" specifies the regional date/time.  The default templates for Forward, Reply, and Confirm now use these date formats.
* The default templates now specify the Calibri font.
* The "Load Default Templates" tool now allows the user to choose which templates should be reset.
* The Ban Domain tool will now display a window where the user can configure the new spam clause.
* When using the Compose/Template tool to create a reply, the reply will be to the selected message in the active folder instead of the default folder.
* The Compose window's "Word Wrap" feature now works properly with UTF-7 encoding.  Previously, each UTF-7 character counted as 3 or 4 characters towards the line length.
* When converting HTML to text, line-breaks inside a <pre> element are now treated just like a <br> tag.
* When adding a curse, whitespace is now automatically trimmed from both ends.
* Changes to the "Character Set" Mailbox property are now visually apparent in all text templates.
* Added a graphical banner to the top of the "Add Spam Clause" window.
* Reduced the delay between the end of spam checking and when the emails appear in the Inbox.
* The email viewer's "Raw" tab has been renamed "MIME" to help distinguish it from the HTML editor's "Raw" tab.
* When choosing Mailbox Properties from the Client menu, if there is only one Mailbox, the user will not be unnecessarily prompted to choose it from a list.
* When composing a Forward, the "Fwd:" prefix is not inserted in the subject if "FW:" is already present.
* The "Text body font/ASCII" and "Text body font/Unicode" settings have been replaced with a single setting.
* Fixed: if there is no text body, and the HTML body contains a stylesheet after the </head> tag, the entire stylesheet was appearing in the generated text body.
* Fixed: after rearranging the order of messages, then restarting Clyton, the order was reverting to its original state.
* Fixed: when dropping emails into a mail folder, using the right mouse button and choosing "Move Here", the files will now be deleted as expected.
* Fixed: when using the "View Message" tool, and there are multiple messages selected, clicking "Delete" was deleting all of the selected messages instead of just the current message.
* Fixed: no text body would appear if it contains malformed UTF-8.
* Fixed: emails with malformed UTF-8 were evading spam detection.
* Fixed: when multiple blacklists are specified, an email could receive a spam penalty multiple times for the same hyperlink.
* Fixed: the HTML editor's toolbar was not saving its customizations.

* Minor interface improvements.
* When an HTML view control is hidden, it will no longer use system resources.
* The character set specified in the MIME header is now subordinate to the character set specified in the HTML code.  Normally the two are identical, as they should be, but in case of a discrepancy, the HTML code will take priority.
* The default "Base64 encoded body" penalty was reduced from 90 to 10.
* Clyton can now cope with the situation where AOL occasionally mis-reports the size of an email when using IMAP4.

* Fixed: certain characters were not appearing correctly in emails that use UTF-8 encoding.


Version 7.0 (November 7th, 2011)
* Added the "Search Mode" field to the bottom of the Search Messages window.  This can be set to one of the following:  "Fast but inaccurate", "Slow but accurate, including attachments", and "Slow but accurate, excluding attachments".  Previously, searches always used the "Fast but inaccurate" mode.  The new modes will fully decode each email before searching them.
* The Attachment Viewer now renders and resizes images much faster.  The user may now hold down the mouse button on the zoom icons.  Zooming in an image too far will no longer result in the image becoming stretched.
* Added the ability to forward a phishing email to www.antiphishing.org.  Right click on the offending email in the Messages Table and choose "Report Phishing".

* Added the "Find Related" tool to the View Email tool.  This will find all emails that are related to the current email, specifically replies and the email that was replied to.

* Ten seconds after the computer resumes from power saving mode, Clyton will now perform a Receive All operation.
* The Send Feedback and Report Exception features now use HTTP to deliver the information to Gammadyne.  The old SMTP method is only used as a fallback if HTTP fails.  This is necessary because some ISP's only allow SMTP to their own mail servers.
* When a DNS record doesn't exist, Clyton will no longer attempt to fetch the record again for 1 hour.  This resovles a scenario that can greatly slow down the spam-checking thread.
* The "Redirect" tool now supports auto-completion.
