Changelog

1.10.1 - Thursday 2 July 2020

Bugfixes

• Actually include the version bump when you push a release! 🐛
• Add flutter docs and reorder flow (#1134)[https://github.com/PostHog/posthog/pull/1134]
• Black all the things! (#1136)[https://github.com/PostHog/posthog/pull/1136]

1.10.0 - Wednesday 1 July 2020

Toolbar

• It's like inspect element, but for user data.

• Easily see the ranking of which parts of the page your users are interacting with the most:

• We learned a ton about our product and website within minutes of trying this out.

Feature flags

• Feature flags let you roll out changes to users with a certain property, or to a percentage of users, or some combo of the two.

Other exciting, enthralling and invigorating features

• Flutter Integration. You asked for it and now it's here!
• Retention page. PostHog already had stickiness, but now there is a table that demonstrates perhaps more clearly how your users are coming back (or not!)

• Better onboarding. We've had a go at redoing how our set up flow works, and will be tracking if it helps more people get through PostHog's own funnel!
• Platform.sh deployment. A very simple, new and trendy way to get up and running!
• Porter development. Join the cool kids and do web development in the cloud. Thank you so much to porter-dev for creating this PR.
• Event name filtering. By popular demand, you can now filter the events table by the event name. Happy debugging your implementations!

Bug fixes and performance improvements

• We are now more privacy friendly - you can discard IP address data
• Added the offer of a free pairing session to the contributing guide - ask us!!
• We fixed a bug with the start times for the session view

• We now let you break down users by their properties (it wasn't working before!)
• We sped up the people page - pro tip: don't load stuff you don't need!
• We disabled batching in the snippet, since this helps prevent data loss
• Fixed a weird bug with moving from sessions to trends
• Fixed person properties being selected, which was causing some issues with the stats.
• We now automatically select hourly if you're looking at data from just today or yesterday - it was weird otherwise!
• We turned today into the last 24 hours - you can now think of yourself as Jack Bauer
• The people modal now has pagination
• We now copy array.js.map as well as everything else to better debug errors
• We now show a warning for old browsers, and feel bad for those in big enterprises that must use them!
• Black now added to post commit hooks, so we don't get crazy all-file reformatting
• Fixed an issue with force refreshes for cache in certain places
• We fixed a failing test problem with team_id
• Improved person properties and pagination
• Solved a Sentry error with overly long text
• We cleaned the configs for release-drafter

1.9.0 - Thursday 18 June 2020

• Sessions view
• You can then see exactly how a user interacted with your app: This should really help with debugging, or just trying to get a detailed view of what users are up to.

Better testing

• Fixed Cypress tests
• Enabled running cypress in parallel, which saved a minute.
• Fixed cypress linting errors and sped up tests further
• Cached PostHog's yarn builds, which took e2e tests down by around 30%.
• Finally, we now wait for PostHog to start serving requests rather than the 60 second sleep when running Cypress.

Management command for millions of events

Set properties to anonymous users
