v1.8.1
------

> Note: This release replaces the built-in Crosswalk web browser from TabSINT framework. Please avoid installing version `v1.8.0` on older devices.

Improvements

- Switched TabSINT source control to https://gitlab.com/creare-com/tabsint and release location to https://gitlab.com/creare-com/tabsint/tags
- Adds option to configure Gitlab results location other than `results`. Previously, gitlab results were only uploaded to the `results` repository within a given group.
- Shows server credentials even when `Admin Mode` is not enabled
- Improves multi-lingual support
- Adds preliminary Japanese language support
- Replaces fragmented documentation sources with single documentation source hosted at https://creare-com.gitlab.io/tabsint
- This release re-adds the crosswalk support. Since TabSINT is run primarily on older tablets, crosswalk will remain critical for the near future.

Bug Fixes

- Fixes permissions issue with csv file export
- Disables back button while TabSINT is open


v1.8.0
------

> Note: This release removes the built-in Crosswalk web browser from TabSINT framework. Crosswalk is no longer supported and causing issues in newer devices. In practice, this means that TabSINT will now be run on devices using the native device Webview.  This may have unintended consequences for TabSINT running on older mobile devices.

Features

- Begins adding support for additional languages using the [`gettext` standard](https://www.gnu.org/software/gettext/) (*Beta*)
    - Additional languages can be provided by editing the [`extract.pot` template file](translations/extract.pot) using a gettext compatible editor (like [Poedit](https://poedit.net))
    - Language support will continue to grow in future releases
- Adds service to calculate CRC32 checksums for file synchronization
- Adds a preference to show *Skip* button while in **Admin Mode**

Improvements

- Updated support for iOS
- Removes python build system used in TabSINT < v1.3
- Removes the Crosswalk web browser from the built apk
- Add convience method (`npm run plugins.debug`) to set `debug: true` for all plugins in the current workspace.
- Adds file method for recursively listing directory contents
- Updates logging for better reliability, searching, and performance

Bug Fixes

- Fixes automatic protocol validation when TabSINT first loads. On first load, the protocol will validate only if the preference is set on the Config page.

v1.7.4
------

> Note: The filenames of results exported locally have been changed to be consistent with the filenames of results uploaded to gitlab servers. See below for the result file naming convention.

Improvements

- Unifies the filenames of results that are backed up, exported, and uploaded to gitlab. The new convention for the filename of exported/uploaded result files is `[protocol-name]/[tablet-id]_[test-date-time]`. (*Previously, the filename included the time of export/upload. Now, the filename includes the time the test was taken - `testDateTime` in the results structure*)

Bug Fixes

- Changes the gitlab results handling to the `Commits` API endpoint. This avoids encoding issues encountered while using the `Respository Files` API endpoint.
- Fixes bugs related to the asynchronous results exporting/uploading
- Fixes automatic protocol validation the first time the app loads a protocol

v1.7.3
------

Improvements

- Adds `group` field to gitlab protocol handling

Bug Fixes

- Fixes url encoding of results uploaded to gitlab
- Fixes bug in gitlab pull where file urls would grow in each loop
- Fixes non-uniform spacing of help popover icon

v1.7.2
------

Features

- Adds ability to change the admin pin. Default admin pin is still `7114`
- Adds ability to configure the start time delay of a wav file. By default, wav files will start to play 1000 milliseconds after the page is loaded. This can be changed using the `wavfileStartDelayTime` property on any page.
- Adds `Audiometer` headset and calibration to the TabSINT server

Improvements

- Sets preference to turn off magnifying glass on long press in UIWebView on iOS

Bug Fixes

- Disallow clicking outside of the partial exam dialog box
- Fix bug where "Loading Protocol..." would persist after loading a protocol
- Fix bug in `omtResponseArea` and `multipleChoiceSelectionResponseArea` related to grading

v1.7.1
------

Bug Fixes

- Fix duplicate `.wav` suffix in files recorded with the `natoResponseArea`

v1.7.0
------

Features

- Incorporates welcome popup the first time the app is ever opened
- Supports Gitlab API v4, including protocol repositories stored in subgroups
- Supports sending and receiving messages to other apps on the device (`externalAppResponseArea`)
- Includes an option to override the automatic volume control on each page
- Include the `natoResponseArea` for recording audio using the internal or external microphone. See the [Nato Response Area Schema](https://github.com/creare-com/tabsint/blob/develop/www/res/protocol/schema/response-areas/natoResponseArea.json) for the allowable input properties.
    - *Note*: This response area requires a closed source tabsint plugin for full functionality

Improvements

- Gitlab based protocols will now default to being tracked by *commit* instead of *tags*. Protocols can still be managed using tags by using the `Only Track Tags` preference.
- Refactors `TabSINTNative` cordova plugin
- Improves style of protocol table
- Improves protocol documentation in the User Guide
