• Support new preview_data parameter for pin previews on Posit Connect (#850).

• Fixed a bug in how pin_upload() handles pin names (#852).

• Improved documentation for S3-compatible object storage (#853).

• Prepend 'https://' to Databricks host if missing (#855).

• Fixed handling of rsconnect::accounts() results (#861).

• Escalated gradual deprecation process for legacy pins functions such as pin() (#864).

Lifecycle changes

• Changed the function signature of pin_upload() to be consistent with pin_write() i.e. arguments like tags must be passed by name and not position (#809).

• Started gradual deprecation process for legacy pins functions such as pin() (#844).

Other improvements

• Added example Python code to pin previews for Posit Connect (#806).

• Fixed a bug in how pins with the same name but different owners on Posit Connect were identified (#808).

• Fixed a bug in handling folders with duplicate names for Google Drive (#819, @UchidaMizuki).

• Fixed how previously deleted pin versions are detected (#838, @MichalLauer).

• Added new board for Databricks Volumes board_databricks() (#839, @edgararuiz).

• Switched writing with type = "parquet" to use the nanoparquet package (#843).

Breaking changes

• Changed the function signature of pin_write() so arguments like type and title must be passed by name and not position (#792).

Other improvements

• Removed content and user caches for Connect altogether. Now, we look up
  usernames and content on the Connect server every time (#793).

• Added new urls item to metadata for a pin (#795).

• Fixed how dots are checked in pin_write() to make user-facing messages more
  clear (#770).

• Improved documentation about Connect caches (#771) and deleting pin versions (#773).

• Added board_deparse for board_url() (#774).

• Fixed how board_gdrive() handles dribble objects (#780, @gorkang and #782).

• New environment variable PINS_CACHE_DIR controls the location of the
  default cache path (#748).

• Added new board for Google Drive board_gdrive() (#749).

• Updated test for new arrow release (#764).

Breaking changes

• pin_write() no longer writes identical pin contents by default, and gains a
  force_identical_write argument for writing even when the pin contents are
  identical to the last version (#735).

Other improvements

• The print method for boards no longer calls pin_list() internally (#718).

• board_s3() now uses pagination for listing and versioning (#719, @mzorko).

• Added type = "parquet" to read and write Parquet files (#729).

• Updated error messages and type checking (#731) along with testing strategy (#724).

• Added new check for whether a new version is the same as the previous version,
  as can happen when writing pin versions very quickly (#727).

• Added new headers argument for board_url(), mostly for authentication, as
  well as new board for Connect vanity URLs board_connect_url() (#732).

• Fixed bug in cache_prune() to correctly find caches for board_url() (#734).

Breaking changes

• Change the function board_rsconnect() to board_connect(), following
  RStudio's rebranding to Posit (#689).

• Changed type = "csv" to use R's default value for stringsAsFactors i.e.
  FALSE (#664).

• Functions for viewing legacy API pins in the RStudio Viewer pane are now
  deprecated (when possible) or removed (#679).

• The functions for accessing Kaggle resource as pins are no longer supported.
  We recommend you use the Kaggle CLI instead (#698).

Other improvements

• Added vignettes describing how to manage custom formats and web-based boards (#631, #685, @ijlyttle).

• Added new board for Google Cloud Storage board_gcs() (#695).

• Added new tags item to metadata for a pin (#677).

• Improved error message for pin_versions() (#657).

• Switched content and user caches for Connect to use environments instead
  of files on disk. This means caches will no longer persist between sessions
  but will be much less likely to end up in a broken state (#667).

• Added write_board_manifest() to write a manifest file _pins.yaml
  recording all pins and their versions to the board's root directory.
  This function only works for boards that are not read-only
  (#661, based on work of @ijlyttle).

• Updated board_url() to handle versions recorded via a manifest file
  (#681, based on work of @ijlyttle).

• Updated code preview on Posit Connect (#690).

• The arrow package is now suggested, rather than imported (#644, @jonthegeek).

• Fixed how Connect usernames are handled in messages, preview, etc (#643).

• Increased datetime precision to the second, for pin_versions() and related
  functions (#642, @tomsing1).

• Pass the dots from pin_write() through to s3_upload_file() and
  s3_uploade_yaml() to support S3 tagging, encryption options, etc for
  pins (#648, #652, @fh-mthomson).

• board_rsconnect() now correctly finds the created date for pins (#623,
  @bjfletcher).

• pin_upload() now better handles path expansion (#585, @sellorm).

• The pin_reactive_*() functions now use the hash (rather than the created
  date) for polling (#595, @thomaszwagerman).

• board_azure() now allows you to set a path so that multiple boards can
  share the same container (#528, @hongooi73).

• board_deparse() is more likely to generate runnable code when used
  with board_rsconnect() (#553).

• legazy_azure() works once again (#527).

• legacy_github() works once again (#549).

• pin_meta() now includes pin name (#544).

• board_register() works better when called directly, due to standardisation
  of cache paths all computation (#529).

• Drop add-ins since they're not tested or documented (#525)
