* Removed PACOTS tracks. albar965/littlenavmap#1298
* Removed wrong check for gone path `StreamedPackages` when reading MSFS 2024 data.

===============================================================================

# Version 4.0.17

* Fixed issue where all VORTAC were loaded as TACAN in MSFS 2020 resulting in wrong bearings and
  wrong type display.
* Now omitting channel for VOR, VORDME and DME for all MSFS simulators. Channel applies only to
  VORTAC and TACAN.
* Fixed issue with double runways when using Navigraph navdata update in MSFS 2020. Example: Add-on

* Fixed issue where a broken CSV import resulted in errors for further imports for userpoints or
  logbook.
* More filtering to get rid of wrong MSFS aircraft indications before starting a flight in the
  simulator. These resulted in an aircraft trail crossing all over the world causing display issues
  and crashes.

===============================================================================

  not shown in the elevation profile or the map.
* Now combining procedures having the same runway transitions. Runway transitions are now collapsed
  to parallel runways (e.g. 16L, 16R) or `All`.
* Now adding navaids not connected to procedures or airways to MSFS 2024 loading process. These are
  required to build Oceanic tracks or off-airways routes, for example.
* Now correcting odd altitude values by rounding. This affected procedure altitude restrictions,
  for example.
* Corrected counting of ILS when loading scenery library.

  `ZUCK ATBUG W66 JNQ  ZWWW`. #1197
* Airport exclude configuration did not work for X-Plane 12 in navdatacompiler.
* Fixed issue where last airway in scenery library was missed adding to the database. This affected
  all simulators except the DFD compiler.

===============================================================================

# Version 4.0.11

This is a release specific to the Navdatareader project.

* Fixed issue where detection of malformed MSFS airports rejected valid airport add-ons with a
  message `Duplicate airport ident`. This happened when add-on developers put more than one of the
  same airport into one BGL file.
* Better detection of the longest runway for airports. Now ignoring water runways if airport has
  water and land runways.
* Fixed wrong airport bounding rectangle calculation for X-Plane airports. Example: KSEA in
  X-Plane 12. This resulted in a too far zoom out when double clicking the airport.
* Better airspace geometry for Navigraph databases and all airspaces read from simulator
  libraries. Now considering Rhumb line segments in Navigraph airspace description. Note that a
  workaround is used to detect these segments for simulator and user airspaces since required
  information is missing in simulators. This eliminates wrong airspace boundaries drawn as
  bows (Great Circle lines).
* Improved display of airspace that touch the poles.
* Fixed duplicate reading of X-Plane `airspace.txt`. The file `airspace.txt` in `Custom Data` now
  overrides the one in `Resources`.
* Added waypoint names to X-Plane and DFD compilers. #1176
* Now doing better capitalization function for waypoint names. #1176
* Added missing columns `name`, `artificial` and `arinc_type` to table trackpoint which could
  result in incomplete waypoint type display.

  `Distance from Mark` and other functions around the antimeridian. #1184
* Increased number samples when calculating elevation from GLOBE data to avoid missing peaks when
  drawing the elevation profile.
* Fixed issue where RealityXP GNS export declared destination airport wrongly as userpoint when
  using export option with userpoints.
* Now using ISO date with offset from UTC in all flight plan files.
* Now getting best guess for user aircraft type designator and category in MFSF. Using keys
  `icao_type_designator` and `icao_model` from file `aircraft.cfg`. Added aircraft category to detect
  helicopters.
* Cleanup in navdatabase compiler. Tables `airport_medium`, `airport_large`, `route_node_radio`,
  `route_edge_radio`, `route_node_airway` and `route_edge_airway` now removed. This breaks
  compatibility with versions before 2020 of *Little Navmap*. The program will show an SQL exception
  if this is the case. Users have to update *Little Navmap* if they run into this.
* View creation in database now disabled.
* Updated minor database version to 29 due to several schema changes. This results in a notice
  about a previous database version although reloading is not required. #1176
* Fixed issue with double and invalid COM frequencies for MSFS airports when using MSFS Navigraph update.
* Fixed issues reading MSA centers for X-Plane where runways were not detected. Now also looking
  for center points of ILS.
* Made GPX file detection more tolerant.
* Fixed issues on OS shutdown where crash was detected wrongly.
