-------------------------- soilDB 1.0 (2013-04-04) ----------------------------
* fetchNASIS() is now much more efficient: faster / less memory used
* new function! fetchKSSL(): experimental interface to (most of) the KSSL data
	- queries can be performed by series name or GCS bounding box
	- data are delivered via CA Soil Resource Lab server

-------------------------- soilDB 0.9-8 (2013-04-03) ----------------------------
* fetchOSD() now immune to queries for non-soils
* improved efficiency in fetch* functions
* NASIS-DMU fetching functions now return more information, still not as complete as pedon-queries

-------------------------- soilDB 0.9-7 (2013-03-01) ----------------------------
* NASIS query functions now return only records from the selected set, please test older code!

-------------------------- soilDB 0.9-6 (2013-02-26) ----------------------------
* new function get_text_notes_from_NASIS_db() -- still needs proper documentation
* bug fixes to PedonPC and NASIS queries, new data elements returned by extended query functions
* SoilWeb queries via URL are now URL-encoded to allow for spaces in soil series names

-------------------------- soilDB 0.9-4 (2013-01-31) ----------------------------
* new function: fetchOSD() returns basic OSD data as a SoilProfileCollection

-------------------------- soilDB 0.9-3 (2013-01-08) ----------------------------
* speed-bump in color-fetching functions from NASIS/pedonPC
* fetchNASIS() now attempts to correct for >1 pedon/site by appending peiid to pedon_id

-------------------------- soilDB 0.9-2 (2012-12-18) ----------------------------
* new functions for getting / plotting the geographic extent of a soil series, using the SoilWeb query service:
  -seriesExtent() : fetches extent as a SpatialPolygonDataFrame
  -seriesExtentAsGmap() : fetches extent and plots on Google Maps (requires dismo package)

-------------------------- soilDB 0.9-1 (2012-11-27) ----------------------------
* updated functionality in fetchNASIS_component_data() pulls mapunit-level data as well as component-level data
* Munsell 'value' is now returned from PedonPC/NASIS fetching functions

-------------------------- soilDB 0.9 (2012-10-24) ----------------------------
* added a surface fragment summary "surf_frag_summary" to the results of get_extended_data_from_NASIS()
  - note: this has not been ported to the related PedonPC queries
* integrated surf_frag_summary data into data returned from fetchNASIS(), stored in @site
  - note: this has not been ported to the related PedonPC queries
* minor bug-fix in horizon-level rock fragment summary SQL which previously mis-classified BD as ST in some, rare cases
  - note: this has not been ported to the related PedonPC queries

-------------------------- soilDB 0.8-3 (2012-09-28) ----------------------------
* site-level data: {elev, slope, aspect} are now named {elev_field, slope_field, aspect_field}
  - this affects the data returned by fetchNASIS() and fetchPedonPC()

-------------------------- soilDB 0.8-2 (2012-08-23) ----------------------------
* compatible with NASIS 6.2
* bug fixes
* taxhistory selection method is preserved in the results
* 'taxonname' is used instead of 'sampled_as' / 'correlated_as'
	! seems to work, but needs further testing

-------------------------- soilDB 0.8 (2012-08-20) ----------------------------
* updating for PedonPC 5.0 and NASIS 6.2
  - site data contains the best-guessed corresponding row from the taxhistory table, based on:
		1) most recent record, or 2) record with the least amount of missing data
  - taxhistory data are now included in the output from get_extended_data_from_pedon_db()
* package is now partially compatible with NASIS 6.2

-------------------------- soilDB 0.6 (2012-06-19) ----------------------------
* tidying up documentation, package dependencies, and NAMESPACE

-------------------------- soilDB 0.5-6 (2012-04-16) ----------------------------
* adding preimlinary functions for querying component data from local NASIS
* fixed minor bug in SDA_query() and added some links to related documentation

-------------------------- soilDB 0.5-1 (2012-02-22) ----------------------------
* fetchNASIS() and fetchPedonPC() now integrate `extended' data
* warning and error messages cleaned-up
* multiple textures no longer cause duplicate HZ rows (NASIS only)
* exteded queries now split frags/para-frags
* silt fraction is estimated from 100-(sand+clay) when possible
* added local NASIS ODBC connection vignette (thanks JMS)
* removed dsn argument from NASIS functions as it should always be 'nasis_local'
* new wide-formatted, boolean representation of diagnostic horizon data
* queries standardized between NASIS/PedonPC
* new fetchNASIS() function for 1-line access to local NASIS data
* new sample data set 'loafercreek'
* basic vignette added, switching to knitr-style vignettes

-------------------------- soilDB 0.3-3 (2012-01-10) --------------------------
* SDA_query() now functional on MacOS/UNIX-like OSes with (SSOAP 0.8-1, XMLSchema 0.6-0, and XML 3.7-1)
  - thanks to D.T. Lang for the updates!
* moving hard to find packages to 'suggested' status: SSOAP, RCurl, XML, rgdal
* new wrapper function fetchPedonPC() for typical site/pedon/hz queries
* new function getHzErrorsPedonPC() for ID-ing pedons with problem horizonation
* NOTE: hz data queries will return 2 rows/hz (error) when multiple texture 
  classes are assigned to a single horizon- this is a bug, not a feature!

-------------------------- soilDB 0.3-2 (2011-12-30) --------------------------
* NASIS/pedonPC queries synced
* minor bug fixes and documentation updates
* updated query structure, switching over to native NASIS/PedonPC IDs

* basic query functionality from local NASIS DB (Jay)

-------------------------- soilDB 0.1 (2011-12-23) --------------------------
* initial version on r-forge
* functions still exist in aqp package... need to move over completely
