Release Notes: Major new v15 release

v15 Notes, Features and Changes. Please read carefully.

v15 is a complete rewrite of the message export functions, both Folders and selected messages. It's the first phase in a modern, mostly WebExtension technology. The new design is a vast improvement in architecture allowing new features and better performance.

For the first v15 release, the following formats have been implemented:

- EML
- HTML and attachments
- PDF and attachments
- Plaintext and attachments

Besides the new PDF with attachments export. There is also a new export status window as well as a new OS notification alternative. A list of features follows:

PDF export with attachments

This is a long requested option. There is one important limitation versus HTML export. The attachments table does not have clickable links. Thus far it has not been possible to produce output with relative links. Either the PDF converter and or the viewers convert all file:// links to absolute links which are not useful. I am hoping there is some way to accomplish this in the future.

Index

The new index file allows you to sort columns by clicking any the headers.

Export Structures

- All attachments in a single directory
If you use a static word like "Attachments", all attachments will go into that directory. In the past that would have produced Attachments, Attachments-1, Attachments-2, etc.

- Attachments saved in the same directory with messages.
In this new option found on the Filenames tab, no attachment directories are created as they are all in the messages directory.

- Attachment directories now have the message date set
For sorting the attachment directories will now have their modification date set to the corresponding message's sent date.

- Experimental "withatts" structure
This structure combines each message with all attachments into the formatted attachment directory. The typical setup would be to set the filename format to your preferred setup say ${subject} and your directory formats to ${subject} as well. This would produce directories for each message with both the message and attachments. Sorting the directories by date or name is possible.

To try this experimental structure place the word:
withatts
in the logging options in the Misc tab. (Proposal by @Rayerd)

Logging options

The new Logging options are on the Misc tab. These are set as a space separated list of log type words. They produce various log and debug output to the Debug console which is accessed by Control-Shift-J. The log types can be combined to produce the additive output. The log types are as follows:
- msgs : Basic message save status
- msgs2 : More detailed debug output for messages
- summary : A summary of the export
- msgparts : Debug info for MIME message parts
- withatts : A temporary option to use the combined message and attachments structure

Menus

The new functions are currently added on top of the old functions and have a (v15) prefix.

The old code will be depreciated once the new functions are stable. This has been done as a cautious approach to the major release. Please use the new v15 functions and report any issues in the Github repository here:

Compatibility for Thunderbird v140 - v151

Note : Thunderbird v148 has fixed the issue preventing PDF Export

I have reconsidered my support for the release channel. With around 78k users, that's to large a group to disrupt. Also I want everyone for
the beta and upcoming release of v15 which is a complete rewrite of the export messages functions. It will also add new features such as PDF export with attachments.

After the next ESR release I will decide on my release policy.
However, please check for ImportExportTools NG support before updating Thunderbird.
