Changelog

This is the changelog for the air quality web interface and its associated HTTP API.

• [API] refers to changes to the HTTP API.
• [Code] refers to internal changes to the code that have no direct impact on the web interface or the HTTP API, but are significant enough to warrant note.
• [Docs] refers to changes to the documentation.

v0.13

• Round dates before making API requests to improve caching potential

v0.12

• Added loading animation while the map is loading
• Added device sensor information to the device info tab in the popup
• Add favicon logo, thanks to @BNNorman
• Moved the close button in the changelog dialog from the bottom to the top of the content
• [API] Improve accuracy of distance_calc for the list-devices-near action by using Haversine's Formula.
• Display how long ago a device was last seen in it's pop-up box
  • [API] HTTP API users can now use the new last_seen property to the list-devices and device-info actions.
• [API] Added new sensors array to device-info output, which lists the sensors that a device has

v0.11.1 - 22nd June 2019

• Drastically improve the performance of the backend SQL queries that power the heatmap and device graphs by over 35x in some cases!
  • For users of the HTTP API, said queries are fetch-data and device-data.

v0.11 - 21st June 2019

• [API] Add new list-devices-near action.
• [API] Clarified that clients MUST ignore properties returned by the API that they do not understand.
• [API] Clarified that clients SHOULD respect the cache-control HTTP header returned by many API actions
• [Docs] Improved documentation about where to get the initial database schema from.

v0.10.4 - 20th June 2019

• [Code] Update dependencies behind web interface
• [API] Optimise fetch-data (the action behind the voronoi diagram heatmap) a bit - it's roughly 100ms faster now
  • More speed will be coming soon with the addition of database indexes
• [API] Add performance counter system, which returns query timing information via the x-time-taken HTTP header in the response to most queries

v0.10.3 - 13th June 2019

• [API] Added new device-data-recent action.
• [Code] Improve documentation of underlying code.

v0.10.2 - 13th June 2019

• [API Docs] Add links to action sections
• [API] Bugfix: Fix default index action so it actually displays the api welcome message

v0.10.1 - 10th June 2019

• Remove heatmap blob radius UI setting
• Add welcome tour, which shows the first time the page is loaded

v0.10 - 10th June 2019

• Change heatmap into a voronoi diagram (#30)

v0.9.2 - 3rd June 2019

• [API] Updated the API documentation with a quick reference of the available actions at the top.

v0.9.1 - 16th May 2019

• [API] Changed the default action. It now displays a helpful message by default instead of routing directly to fetch-data.

v0.9 - 9th May 2019

• Add heatmap gauge at the right-hand-side
• Display the changelog the first time a user loads the page after an update

v0.8 - 23rd April 2019

• Update heatmap colours to match the official DEFRA standards
• Bugfix: Allow different reading types to be selected once more in the bottom-left
• Bugfix: Immediately update heatmap when changing the blob radius

v0.7.1 - 16th April 2019

• [API] list-reading-types no longer returns an error if a device hasn't submitted any readings yet
• [API] Remove device locations from fetch-data action to boost performance

v0.7 - 14th April 2019

• Added experimental heatmap time slider!

v0.6 - 13th April 2019

• [Build] Continuous Deployment is now active! More time for development, less time manually updating the server.
  • The way the server is configured has completely changed, so please report any issues you encounter

v0.5.6 - 6th April 2019

• Add new Raspberry Pi Installation Instructions from @BNNorman

v0.5.5 - 5th April 2019

• [Build] Use local version of composer
• [Build] Check for pdo_mysql PHP module

v0.5.4 - 14th March 2019

• [API] Added device altitude information to list-devices and device-info actions
• [API] Added device type id property to list-devices action

v0.5.3 - 7th March 2019

• Tweak x axis labels
• Build script: Improve first-time setup experience

v0.5.2 - 1st March 2019
