himach 0.3.2

• New graphics: Route density charts, for routes combined with forecasts. See the Advanced Vignette.
• Bug fixes: package dependencies, package documentation.

himach 0.3.1

• Bug fixes: Prettier cutting of background map at dateline.
• Dependency upgrades
• using edition 3 of testthat
• removing deprecated syntax in tidyverse

himach 0.3.0

• New graphics options: in map_routes colour lines by a flight frequency variable or by number of accelerations to supersonic; now can also plot a simple speed/distance/time/altitude profile with profile_routes.
• Added a section on cache housekeeping to the advanced vignette.
• Bug fixes: Solved map ‘leakage’ at dateline, and make_AP2 copes with vectors of airport pairs correctly now.

himach 0.2.3

• Fixes for solaris running old GDAL: switch to storing crs_Atlantic etc as strings.

himach 0.2.2

• Fixed crash when routing over very short hops (say for re-positioning flights).
• (development) Bug fixes: map leakage solved, summarise_routes now works with 3-letter airport codes as well as 4 (though default is still ICAO codes, not IATA codes for airports).
• Removed use of Travis for code coverage.

himach 0.2.1

• Patch so that tests work ok with sf v1.0+.

himach 0.2.0

• More precise estimate of time penalty for acceleration from subsonic to supersonic cruise (or v.v.). Perhaps 1% difference in timings as a result.
• Faster map plots, since maps are simplified (a little) now, by default.

himach 0.1.2

• Tweak test for CRAN.
• Fixed issue when using package functions without loading package.

himach 0.1.1

• Fixing check errors on other platforms
  • Errors involving “NULL: PROJ available?” appear linked to this ‘older GDAL’ issue in sf. So implemented a work-around in various examples and vignettes.
  • Use make_aircraft(warn = FALSE) in examples & vignettes just to eliminate warnings. Still think this merits a warning in normal use, because the default aircraft are unlikely to be fit for purposes beyond testing.
  • bug fix: Mach 0.84 comparison from summarise_routes now uses 0.84 instead of 0.85.

himach 0.1.0

• First version targeted for CRAN release.
• Fixes a number of bugs in the avoid-area functionality.

himach 0.0.2

• Major overhaul of the approach to smoothing from a Dijkstra-style route to a great-circle route, to handle the 1% of cases where the old approach didn’t work well.
• Further speed improvements.

himach 0.0.1

• First version using the s2 capabilities of the sf package. This gives more robust plotting, and a number of internal speed improvements.

These binaries (installable software) and packages are in development.
They may not be fully stable and should be used with caution. We make no claims about them.
