Version 26.0 (August 9th, 2021)

String literals can contain unicode characters.
Some functions have been removed, renamed, or combined.

When you upgrade to 26.0, the Incoming Script and all templates will be automatically adjusted so that no change in behavior occurs.

Fixed various issues with externally copying .eml files into Clyton's folders when they have long file names.
Fixed: HTML Editor: Style Editor: the Font-Family field was not being applied correctly (since 22.0).

The "Validate CSS" tool has been written from scratch and is now internal to Clyton. Previously, the CSS was sent to the W3C validation service website.

When an email is deleted from an IMAP4 server, steps are now taken to ensure that it goes to the server's Trash folder.

Added the ability to specify a color for a folder's tree branch.

Fixed: Compose: Style Editor: the "Apply to each element" scope did not work correctly in some situations.

Version 19.1 (January 7th, 2019)

Validate HTML: this now uses an internal validator instead of the W3C online service.

Also, it allows you to jump directly to where a warning or error occurred.
In the event that an email cannot be downloaded, a secondary error code is now reported that may help with troubleshooting.

If an email has no HTML body, Clyton will no longer look for an HTML attachment to use in its place.
Redirect: if an S/MIME signature is present, it is now stripped. Better to have no signature than one that is invalid.

Export Contacts: the size of the export file is now reported.
Messages Table: on the context menu, some of the tools were moved to a "Table Tools" submenu.

The "Unsubscribe And Delete" tool, when it must query a web page instead of sending an email, will now display a popup window with the web page in it. This is necessary because sometimes the user must submit a form to complete the unsubscription. This tool also now has a hotkey, Alt+End.

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.

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.

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".

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.

Version 1.2 (May 27th, 2008)

Numerous user interface improvements. Please press Ctrl+Alt+Shift+F5 to reset SystemG, then reload your preferred skin.
Added the "Editor Menu" button to the HTML editor toolbar.
Added the ability to paste plain text into the HTML editor (stripped of all text formatting).
Improved icons and icon rendering.
Added the "Metal" skin.
Updated the SSL module.
When the mouse hovers over a partially obscured tree branch, the full branch name will now appear in a popup window.
The "Spam Check" tool will no longer stop testing if the sender is trusted or if the spam score goes over the threshold. This does not apply to regular spam checking, only the tool.
Big improvement to quoted-printable decoding speed.
The installer will now warn if it does not have admin rights. It will also attempt to loosen the security settings on the installation directory (to prevent problems with Vista).
On startup, the Inbox table sort setting is now obeyed even when the number of messages exceeds 350. All other folders will disregard table sorting when the message count exceeds 350 (for performance reasons).
The Sent Folder's "Maximum Message Age" feature was using the Received date like all other folders. It now uses the Sent date.
Lowered the "Leading Image" spam penalty from 80 to 60.
Lowered the "Penalize Symbols" spam penalty from 100 to 60 and increased the threshold from 20 to 25.

When a new sender is trusted, all messages from the sender that are in the Spam or Quarantine folder are moved to the Inbox.
When creating a Mailbox, if the "Lock At Startup" box is checked, the Mailbox will no longer be initially locked.
The Compose Window will now immediately reject an illegal From: header.
