Hi Inbox Developers,

Over the past month we've been hard at work at Inbox HQ as well as around the globe to improve the Inbox Sync Engine, API, and SDKs, and are proud to announce the release of version 0.3.0. You can find all the gory details on GitHub, but the high-level changes are noted below.

API changes

While we strive to maintain API stability, we've been working with folks building apps on top of Inbox and have found that the following API changes make some apps drastically simpler—enough to justify a backwards-incompatible change.

• We've changed a number of endpoints to refer to items by item_id or item_ids rather than just item for greater clarity. This includes:
  • Rename the namespace attribute of all objects to namespace_id.
  • Rename the thread attribute of messages and drafts to thread_id.
  • Rename the messages and drafts attributes of threads to message_ids and draft_ids, respectively.
  • Rename the thread query parameter for filtering messages and drafts to thread_id.
• The Draft update endpoint now uses the PUT HTTP method, consistent with other objects like threads and messages.
• Drafts now have a version attribute, and updating a draft now simply changes its version, instead of creating a new draft object. (Note that updating or sending a draft now requires the version value as a parameter, in order to prevent write conflicts.)

New Calendar and Events APIs

These new APIs allow access to calendar and event information for accounts from Google, iCloud, Hotmail/Outlook.com and Microsoft Exchange (contact [email protected] to request beta hosted access). Check out the docs to get started!

New SDKS

We've released Ruby and Python bindings, making it even faster to get started building email apps against the hosted Inbox API.

Here's a quick Python example:

inbox = APIClient(APP_ID, APP_SECRET, token)

namespace = inbox.namespaces.first()
for thread in namespace.threads.items():
    print thread.subject

Other feature additions

• Attachment tag added to threads which have attachments.
• Create an archive folder where necessary for various providers.
• Namespace endpoint now support filtering options such as limit, offset and email_address.
• Files endpoint supports delete for files that are not currently attachments.
• User-created tags can be deleted.

Bug Fixes

• Propagate unread status changes to threads in update_metadata.
• Better handling of HTML stripping for snippets.
• Remove unused UIDNEXT from IMAP mailsync, since some providers don't support it.
• More graceful handling of various IMAP errors.
• Improved coverage for unit tests, notably over the API calls.
• Refactor message / parts / blocks relationship to avoid creating new blocks when they are attached to messages.
• Remove duplicated code around SMTP mail sending.
• Truncate fields if they are too long on calendar/event parsing.
• Properly check to, cc, bcc fields in drafts for formatting.

With love from Team Inbox, -- mg, spang, kavya, eben, ben, charles, karim, dwayne, and zoë

Hi Inbox Developers,

We are pleased to announce a new release of Inbox. We are again excited to see the enthusiasm from the community and we've been hard at work integrating change requests, adding new features and fixing bugs.

Here's what's changed since the last release:

New Features

• Support for generic providers. We've now made it easier to add support for more providers through the "providers.py" file, where you may specify the relevant information for new providers without modifying other parts of the code.
• Basic multicore support for mailsync.
• Automatic detection for providers which support RFC4551 / 7162 (CONDSTORE).
• An improved threading algorithm for providers which do not support automatic threading on the backend.
• Theinbox-auth command is now scriptable with the options --exit_after_link and --token.
• Better handling for invalid API query parameters.
• The API message representation now includes detailed attachment information such as content_type, size, and filename.
• Initial support for Outlook.com/Hotmail including sending, receiving, archiving and draft management
• The drafts API supports ?thread=[filter], which returns all the drafts of a thread.

Bug Fixes

• Improved handling for accounts which no longer have valid credentials or cannot connect to the underlying provider.
• Updated html2text version to avoid issues with malformed html.
• A significantly reduced number of database connections are now needed to sync accounts.
• Cleanly handle corrupted Gmail metadata cache files.
• SIGTERM is properly handled in inbox-start/
• The file attachment API call now returns a proper JSON response.
• Assorted drafts/sending bugs.
• Many performance improvements and other various bugfixes.
• Improved provider identification during authorization process.

Upgrading

If you're running Inbox on your own infrastructure, make sure you've disabled the sync, API and syncback processes and run the following to upgrade:

$ ./setup.sh

Thanks to everyone for their continued support and interest in Inbox! If you run into problems with the latest, we hope you'll file an issue[1] or hop onto ##inbox to get help.
