# Changelog

## v0.19.2 (2019-02-12)

- Bug fixes
    - Short code maps are now stored in the correct file encoding (`UTF-8`) to allow parsing short code maps with characters like umlauts ([#15](https://github.com/elixytics/ua_inspector/issues/15))

## v0.19.1 (2019-01-05)

- Enhancements
    - The (soft) deprecated download tasks `ua_inspector.download.databases` and `ua_inspector.download.short_code_maps` are no longer displayed in the output of `mix help`

## v0.19.0 (2019-01-03)

- Enhancements
    - All database files (parser databases and short code maps) can be downloaded using a single mix task `ua_inspector.download`
    - Downloading the databases ensures hackney is started to allow calling `mix run --no-start -e "UAInspector.Downloader.download()"`
    - Finding the data table is now done via a named lookup table instead of calling the database state server
    - If you need to check if all databases are loaded (i.e. "no longer empty") you can use `UAInspector.ready?/0`
    - OS Families are no longer hardcoded inside `Util.OS` but read from the original source and stored in a short code map
    - OS Families used for desktop detection are no longer hardcoded inside `Util.OS` but read from the original source and stored in a short code map
    - Reloading will now issue a warning if no database path is configured while resuming operation with an empty database

- Soft deprecations (no warnings)
    - The individual download tasks for databases and short code maps have been removed from the documentation. They are still completely functional but will eventually be removed after a proper deprecation phase

## v0.18.0 (2018-08-15)

- Enhancements
    - Configuration can be done on supervisor (re-) start or when running the mix download tasks by setting a `{mod, fun}` tuple for the config key `:init`. This method will be called without arguments.
    - Old data tables are deleted with a configurable delay after reloading to avoid race conditions (and the resulting empty lookup responses)

- Bug fixes
    - ETS tables of short code maps are now properly cleaned after reload

- Soft deprecations (no warnings)
    - Support for `{:system, "ENV_VARIABLE"}` configuration has been removed from the documentation. It will eventually be removed completely after a proper deprecation phase

## v0.17.0 (2018-02-18)

- Enhancements
    - References to `piwik` (like database URLs) have been updated to reflect the rename to `matomo`

## v0.16.1 (2018-01-17)

- Bug fixes
    - Broken module naming for the mix download tasks has been fixed ([#12](https://github.com/elixytics/ua_inspector/issues/12))

## v0.16.0 (2018-01-05)

- Backwards incompatible changes
    - Minimum required elixir version is now `~> 1.3`

## v0.15.1 (2018-01-17)

- Bug fixes
    - Broken module naming for the mix download tasks has been fixed ([#12](https://github.com/elixytics/ua_inspector/issues/12))

## v0.15.0 (2017-12-30)

- Enhancements
    - All databases can be reloaded (asynchronously) using `UAInspector.reload/0`
    - Supervision can now be done without starting the application ([#8](https://github.com/elixytics/ua_inspector/pulls/8))
    - The database downloader has been promoted to a directly usable module

- Bug fixes
    - If a device has no type configured in the database previously `nil` was returned instead of the expected `:unknown`

## v0.14.0 (2017-05-31)

- Enhancements
    - Empty user agents (`""` or `nil`) now return a result without performing an actual lookup. By definition an empty user agent is never detected as a bot
    - System environment configuration can set an optional default value to be used if the environment variable is unset

- Bug fixes
    - Properly handles `nil` values passed to the lookup functions ([#7](https://github.com/elixytics/ua_inspector/issues/7))

## v0.13.0 (2016-09-08)

- Enhancements
    - Engine versions are extracted
    - Remote url of database files is now configurable. Due to naming changes a complete re-download is necessary
    - Remote url of short code map files is now configurable

## v0.12.0 (2016-08-18)

- Enhancements
    - Database downloads are done using hackney in order to prepare an upcoming auto-update feature
    - If the initial load of a database (during process initialisiation) fails a message will be sent through `Logger.info/1`
    - If the initial load of a short code map (during process initialisation) fails a message will be sent through `Logger.info/1`

- Backwards incompatible changes
    - Completely unknown devices now yield `:unknown` instead of a struct with all values set to `:unknown`
    - Downloads are now done using `:hackney` instead of `mix`. This may force you to manually reconfigure the client
    - Minimum required elixir version is now `~> 1.2`
    - Minimum required erlang version is now `~> 18.0`

## v0.11.1 (2016-04-02)

    - Short code mappings are reloaded if a storage process gets restarted
