K9 is an experimental fork of the core Android POP/IMAP email client. Primarily, K9 is focused on making it easy to chew through large volumes of email.
What's New in This Release:
· Super-dense message lists are now shown if you set the number of message preview lines to 0 & disable contact pictures in Global Settings -> Display
· New Slovak translation
· Updates to Czech, Spanish, Finnish, French, Korean, Polish and Russian translations
· Added autoconfiguration for Fastmail.FM
· Tightened up the account list display for narrow devices
What's New in 4.403:
· This version fixes a crashing bug on ICS & JB.
What's New in 4.401:
· This release fixes a few crashing bugs in version 4.400.
What's New in 4.201:
Initial Setup:
· Automatic folder config for Yahoo!, Gmail, and other RFC6154 SPECIAL-USE-compliant servers
· Set the IMAP namespace for Gmail during auto-configuration
· Changed UI to allow selecting the empty IMAP namespace
· Set 'When I delete a message' to 'Delete from server' by default for IMAP on automatic setup like manual setup does
· Set default names for Archive and Spam on manual config like automatic setup does
· Added autoconfiguration settings for several providers
Options:
· Option to have confirmation on deleting starred messages
· Option to strip signature from quoted text in replies
· Extended setting to hide subject in notification area (never, when locked, always)
· Save settings changes "on pause" rather than "on back" so we actually save settings when a user hits home or menu or whatever
· Added font size setting for text input fields in the message composition screen
· Added a setting to disable marking messages as read on viewing
· Enable system zoom and disable gestures by default
· Add discard confirmation dialog when pressing back in message compose
· Option to now refuse to save drafts of messages marked as encrypted
Composing mail:
· Added a button to switch the identity in the message composition screen
· Prompt user which email address to use when a contact with multiple email addresses was picked
Replying to mail:
· Fixed quoting of text/plain reply when sending text/html messages (builds plain reply separately instead of converting from the HTML)
· Forwarded messages always use the quoting style 'Header'
· You can now can have reply and signature before quote, reply and signature after quote, or reply before and signature after quote (setting reply after and signature before still corrects to both after)
· Convert quote characters in plain text messages to blockquotes in the HTML version. "Be like Thunderbird."
· Colorize quoted text that has been converted to HTML. Like Thunderbird, but optimized for mobile (no right margin quote bar, thinner left margin quote bar).
· Added 'From:' addresses on "reply all" even when 'Reply-To:' is set. Don't repeat address in 'To:' field if it's already included because it's the 'Reply-To:' address.
Reading mail:
· Preserve header order (with the exception of duplicate headers like 'Received' they all show up where the first one did)
· Improved zooming/scrolling when viewing a message
· Added long-press popup menu to links in email message display
· Workaround to detect the charset from HTML mail without charset parameter on the header
· Added button to show unnamed and inline attachments
Message list:
· Added batch buttons for 'Archive' and 'Move'. Made batch buttons configurable
· Remember the most recent sort setting in the message list
· Added a "sort by arrival" option
Widget:
· Added widget to display the unread count for an account
· Added launcher shortcuts for special accounts/folders ("Unified Inbox" and "All messages")
Protocol support:
· Fixed the parsing of response data for WebDAV requests
· Fall back to HELO command if the server doesn't know EHLO (SMTP)
· Improvements to mail sending timeout issues
· Yahoo! IMAP seems to no longer require 'ID ("GUID" "1")' over non-3G. See http://mobile.yahoo.com/mail for IMAP setup instructions.
Platform compatibility:
· Support ACTION_SEND extras when handling ACTION_SENDTO. Too many applications get this wrong and rely on the undocumented behavior of the AOSP Email app and Gmail
Notable bug fixes:
· IMAP message UIDs are 32 bit unsigned values and cannot be stored in int, so we now parse them as long.
· Disable special screen reader mode on ICS. The default message view has special accessibility features already.
· Don't save to drafts if drafts folder is -NONE-
· Hide buttons & settings that don't do anything on POP3 accounts
· Delete attachment metadata and thumbnails when deleting attachments
· Reset unread/flagged count on "empty trash"

What's New in 3.207 / 3.390:
Major new features:
· added launcher shortcuts to accounts, refs issue 1025 - thialfihar
· Support for inline PGP digital signatures and encryption with APG - thialfihar
· Support Emoji for DoCoMo. Emoji icons are derived from http://start.typepad.jp/typecast/ - jca02266
· Added menu option to select & copy text in the message view. - cketti
· Allow users to choose an outgoing identity from any account during message composition - fiouzy & cketti
· First pass at a "download the rest of this message" button - jessev
· Added optional "Archive" and "Spam" buttons to Message View - thialfihar
Internationalization:
· Added Czech localization provided by lubekgc (Thanks!) - cketti
· Added Japanese translation provided by hatty. - jca02266
· Updated french translation (thanks, p.lucauclair) - cketti
· Complete French translation added. Cheers, plauclair. - thialfihar
· Updated Polish translation with patch provided by borszczuk - cketti
Build system:
· Google got rid of the android-6 distribution in the SDK. We now build against android-8, (though we're still backwards compatible to android-3.) - jessev
Selected internal improvements:
· Use of constants for immutable empty arrays (prevent useless memory allocation) - fiouzy
· Try to avoid a bunch of reallocations as we grow the temporary output stream by defining its size if we can get it - jessev
· Backport an update to getTextFromPart from AOSP as of 290348 - dealing with OOM as we import large messages - jessev
· Switch from the incomplete (but compatible with java 1.3) mime4j charset alias resolver to the core java nio version with a better charset database; rather than falling back to not showing the user a failing message, fall back to showing the user the message as ascii -- it makes it possible to get something out of an unknown-charset message, rather than just a "ha ha. no." error. - jessev
· use "http://" as baseUrl in WebView instead of "email://", refs issue 267 - thialfihar
· Better handling of cases where a special folder is set to INBOX (e.g. Sent folder = INBOX). Make sure we count unread messages and don't exclude the Inbox from notifications in this case. Fixes issue 1817 - cketti
· Synchronize iterator accesses to mAdapter.messages to avoid ConcurrentModificationException in MessageList. Fixes issue 1598 - fiouzy
· Avoid NullPointerException when trying to move a message before it is fully loaded (in message view). Fixes issue 1957 - cketti
· When counting remote unseen/flagged messages, don't window to only the most recent 300 messages - Since we display this # to the user, the "last 300" heuristic ends up confusing and wrong on a regular basis. - jessev
Configurability:
· added a setting for language, overriding the system locale settings - thialfihar
· Add a per-account setting to choose how much of each message to download automatically. - jessev
· Added option to return to the message list after deleting a message in the message view activity. Fixes issue 1634 - fiouzy
· Added preference to go to Integrated Inbox on application startup. Fixes issue 1797 - cketti
· Implements new setting "Sync remote deletions" which is checked by default. When unchecked, K-9 Mail will no longer remove messages from local storage just because the message was removed from the server. This functionality works for all account types. Messages will still be removed from the local store in order to stay within the limit imposed by the "Number of messages to display" setting. Fixes Issue 794 - danapple0
· Added the vibrate pattern preference. Fixes Issue 1915 - jca02266
· Added option to specify the message quote prefix character/string (default ">"). Applied patch provided by fiouzy (Thanks!) with some small modifications. Fixes issue 1830 - cketti
· Added option to specify Reply-to address for an identity. Patch provided by fiouzy (Thanks!). Fixes issue 1762 - cketti
Performance:
· With all the other performance work we've been doing, getting a message into the messagelist is now much, much faster. Intentionally loading the whole mailbox before we let the user interact with the list is increasingly painful. A 250 message mailbox takes 2+ seconds to "unlock" on a modern phone. - jessev
· Rather than doing a full count of all the unread messages in each and every folder for each message downloaded in a session, factor the "unread messages" count out into the calling code. It's slightly less clean, but a pretty huge performance gain. - jessev
User Interface:
· Remove URLs from message previews. Suggested by Kevin Falcone - jessev
· Show "From", "To", "Cc" headers in "raw" form when displaying all message headers. Fixes issue 1805 - cketti
· Support inline images in HTML mail. - jca02266
· Don't show "To: " if the only recipients were ccs and bccs. - jessev
· Experimental changes to tell WebView that the HTML versions of messages we generate from ascii are "mobile-optimized" - jessev
· Don't fire off a notification about new mail before we finish initializing an account. This should prevent "(null)" notifications on account setup- jessev
· K-9 wasn't properly clearing the thumbnail/tmpfile cache. We now properly clear it up on start, which causes K-9 to leak less flash memory AND fixes the "Wrong thumbnail" bug. - jessev
· After we download attachments, get rid of the "old" attachment views - jessev
· When marking a message as read as we're opening it from the message list, don't "bother" sorting the messagelist again before opening the message, it adds a bit of slowness when we don't need it and we'll sort again when we get back to the message list. - jessev
· remember which message was selected in MessageList in case the list changes while the dialog is up - thialfihar
· Applied patch by ndarilek (thanks!) to add android:contentDescription attributes to unlabeled input fields to improve accessibility. - cketti
· Moving sendMessage and saveMessage into AsyncTasks to make the send/save buttons much less janky - jessev
· Remember last selected folder for copy and move operations and scroll this folder into view on subsequent folder selections (for move and copy operations). - cketti
· Added account settings for "archive" and "spam" folders. See issue 3. - thialfihar
· Show To, Cc and From headers on the part of additional headers without fetching all headers. Fixes Issue 1914 - jca02266
· Hide the message header while flipping messages, rather than displaying the "wrong" thing during load. - jessev
· Ask the user to save a draft message or discard it when the press the back button. - jca02266
· Start at replacing text buttons with image buttons. - jessev
· make MessageList remember the last selected item - thialfihar
· Save/restore In-Reply-To/References headers on configuration change Fixes Issue 1887 - fiouzy
Sync improvements:
· Android is growing up a bit. artificially limiting the user to attachments of only 5MB is counter-productive, bump the artificial limit to 128M - jessev
· If we hit a race condition and download a message after it's already been marked as suppressed, then don't actually save it locally - jessev
· Only ask for POP3 capabilities before authorization if TLS should be used. Always ask after authorization. - cketti
· A race condition made the outgoing certificate being compared to the old incoming mHost, throwing an exception with an untrusted certificate dialogue to accept or decline. - jessev
