v1.1.2

As more and more people start using trackintel regularly in their research work we could identify and fix several bugs leading to an even more stable version of trackintel. Apart from those this release features a significant update for speed and stability for our trip generation algorithm (#220) and a better support for the interaction with postgis (#264). We also updated our documentation style and we now have links to the source code and a better contrast for our function highlighting (#237). Finally, starting from this release our trackintel accessors show the correct docstrings (#274).

New features and enhancements:

ENH: Cleaner and faster trip generation (#220)
ENH: Copy docstring for accessor methods. (#274)
ENH: Update read_*_postgis functions. (#264)
ENH: gap_threshold for generate_stps (#254)
ENH: Added links to source codes (#237)

Bug fixes

BUG: fixed 279 + tests (#282)
BUG: Index error in pre_filter_locations (#276)
BUG: Fix tripleg generation (#283)
BUG: Fix errors occuring in geolife tripleg generation (#238)

v0.6.0

trackintel is now one step closer to our v1.0 goal. Most notably trackintel has updated the staypoint and tripleg generation algorithms (#194, #193) which covers more cases and are all temporal gap aware! trackintel tutorial is now available and focuses on the core functionalities (#190, #185). Our IO functions are now cleaner (#192) and much more efficient (#175, #179).

Major new features and enhancements:

ENH: rearange trajectory distance module (#187)
ENH: faster csv reading (#175, #179)
ENH: we now use black to reformat our code (#196, #195)
ENH: we update our staypoint and tripleg generation algorithms (#194, #193)
ENH: trackintel tutorial now available (#190, #185)

Documentation, testing and clean-up

DOC: readme.md now contains simple instruction on using trackintel (#198)
DOC: ensure consistency in IO and Model modules (#192, #179)

v0.5.1

Trackintel is under very active development. Because of that many features that are not on the official roadmap were included and many different issues were fixed. The main contributions featured in this release are concerning consistency and updates to the documentation such as a new illustration of the data model (#127).

New features and improvements:

• The tripleg generation was reworked and tested #124
• Performance update for the generate_staypoints method #115
• the trackintel read_csv functions now support a crs #137

Consistency

• ID is now always used as an index in the dataframes #120
• Missing data is now always modeled as np.nan #126, also in integer datatypes #136

Bug fixes:

• A fix for the auto-release workflow that triggered multiple actions #113
• All accessors now display the correct error message in their validation method #138
