Version 8.6-rc1 (8.6.0)

• Improve reliability of identifying Drafts folders, beyond ones that are specially flagged as such
• Update the "Date" header when scheduling the next occurrence of a recurring message
• Warn user if a message has been blocked because its late grace period has expired
• Allow "block late messages..." option without "enforce schedule restrictions at send time" option

Patch release v8.5.4

• Fixes bug with locating the draft folder message enumerator for local drafts folder.

Version 8.5-rc4 (8.5.3)

• Indicate in draft folder column whether a message is valid (unencrypted) and scheduled by this instance.
• Fix case where an account has no special "drafts" folder.
• Minor improvements to the options page interface.

Version 8.5-rc3 (8.5.2)

Changes:

• Automatically re-save edited drafts to clear x-send-later headers
• Send rate throttling is possible, but requires modifying an 'advanced config' parameter for now.

Version 8.5-rc2 (8.5.1)

Changes from 8.5.0:

• Re-implement the status bar indicator and menu
• Fix locales in draft folder column
• Ensure overlay scripts are injected in correct order every time
• Fix the state lock for using 'place in outbox' when spell-check is enabled

Version 8.5-rc1 (8.5.0)

Changes from previous version:

• Access key shortcuts are available within the message composition window and the popup dialog
  • In the composition window, Ctrl+Alt+1/Ctrl+Alt+2/Ctrl+Alt+3 execute the user-defined shortcuts (15 min/30 min/ 2 hour delay by default)
  • In the popup dialog Ctrl+1/Ctrl+2/Ctrl+3 also execute the shortcuts, Ctrl+Enter activates the "Send at ..." button, the "Send Now" and "Place in Outbox" buttons are connected to the same access keys as they were in the 7.x branch, with underlined characters in the button text to indicate what those keys are, and the shortcut keys can be manually bound to whatever arbitrary access key you'd like by placing an & character in the shortcut label immediately preceding the character of your choice.
    • E.g. creating a shortcut called Next &Work Day would be rendered in the shortcut button as Next Work Day (W should be underlined, but github won't do that), and could be activated with Alt+Shift+W on Windows and Linux, or Ctrl+Option+W on Mac.
• Fetch messages from Drafts folder only as absolutely necessary.
• More judicious console log handling.
• Date time locales are fixed for users whose default locale was different than their UI locale.

Version 8.4.5

This version fixes the most nagging bug that Send Later has been plagued with (issue #16), which prevented messages from being sent at their scheduled time. It also incorporates everything from the 8.3 branch.

Because of the magnitude of issue #16 I made the somewhat risky choice of rushing this patch through its usual beta stage and directly out to ATN for review. It is currently pending Mozilla review and will probably be available there some time tomorrow.

If you are experiencing the above mentioned bug, you can install the .xpi file attached here, or just wait for this patch to be available through addons.thunderbird.net. If you have not experienced this issue, then you shouldn't notice any difference one way or the other.

Beta version 8.4.4

This version implements a new method of scanning draft messages for scheduled messages which I'm hoping will improve reliability of that functionality. In particular, I'm hoping that this will address #16 by bypassing Thunderbird's message handling API.

Version 8.3-rc1 (8.3.0)

Wrapping up work on this for the weekend, and generating a release that's up to date with the current main branch.

Changes:

• Lots of minor improvements and fixups to the scheduler dialog.
  • Option to place message in outbox rather than send immediately
  • Automatically adjust input based on schedule restrictions
  • Relative time format is synchronized with the actual time at which send later executes (not necessarily on the minute)
  • Relative time text updates periodically while the dialog remains open, rather than only being set when the input fields change.
  • Fix bug with "save these values as defaults" in which default values were not properly restored.
• Force the toolbar to be visible, and ensure the send later button is added to it (backported to 8.2.1)
• Fix locales, and merge translation changes from the 7.x branch
• Implement all the same pre-send checks as Thunderbird's native send operation, and make sure they only run once.
• Set reply/forward flags when responding/forwarding messages via send later (backported to 8.2.1)
• Handle errors in cases where saveAsDraft fails to complete.
• Fix hide/show and popuplate send later column immediately after addon is installed (backported to 8.2.1)
• Prefer the future when parsing date/time entered by hand (backported to 8.2.1)
• Delay automatic updates until next restart (will not take effect until an update is available via ATN after this version)
• Offer opt-out from repeated resent message warnings

Version 8.2-rc2 (8.2.1)

Backport some patches from 8.3 before submitting to ATN for review.
