The changes are fully described at
http://trac.osgeo.org/gdal/wiki/Release/1.8.0-News
However, the following are the highlights.
In a nutshell:
* New GDAL drivers : GTX, HF2, JPEGLS, JP2OpenJPEG, JPIPKAK,
KMLSUPEROVERLAY, LOS/LAS, MG4Lidar, NTv2, OZI, PDF, RASDAMAN,
XYZ
* New OGR drivers : AeronavFAA, ArcObjects, GPSBabel, HTF, LIBKML,
MSSQLSpatial, NAS, OpenAir, PDS, PGDump, SOSI, SUA, WFS
* Significantly improved OGR drivers : DXF, GML
* New implemented RFCs:
o RFC 7: Use VSILFILE for VSI*L Functions
o RFC 24: Progressive data support in GDAL
o RFC 28: OGR SQL Generalized Expressions
o RFC 29: OGR Set Ignored Fields
o RFC 30: Unicode Filenames
o RFC 33: GTIFF - Corrected !PixelIsPoint Interpretation
* New utility : gdallocationinfo
Backward compatibility issues:
* MITAB driver: use "," for the OGR Feature Style id: parameter
delimiter, not "." as per the spec. Known impacted application:
MapServer?
* RFC 33 changes the way PixelIsPoint? is handled for GeoTIFF
* GML driver: write valid <gml:MultiGeometry> element instead of
the non-conformant <gml:GeometryCollection>. For backward
compatibility, recognize both syntax for the reading part
The 1.7.1 release was prepared and issued primarily to deal with ticket 3382,
relating to the fact that GDAL 1.7 has had a significant regression in that
all Erdas Imagine (HFA/.img) files produced are unreadable by non-GDAL software
including released versions of ArcGIS and Erdas Imagine. Following is a list
of all bug fixes since the 1.7.0 release.
== General ==
* MacOS X: Support versioning for framework builds
* FreeBSD: fix --with-threads configuring
== GDAL / Raster ==
* HFA/Imagine: Fix very serious 1.7 bug with blank layer names which was
producing .img files unreadable in non-GDAL software
* HFA: Ensure nodata values carried into overviews
* HFA: Fix support for files with nonstandard mapunits
* NITF: Improve NITF spec compliance when generating JPEG compression
* NITF: Improve dateline handling for CADRG products
* NITF: Return GCPPROJECTIONX metadata when we can't transform polar
* GeoRaster: Avoid error messages when looking up epsg codes
* DODS / GDALCopyWords(): Fix bug with negative offsets/flipping
* PCIDSK: Fix new bug with UTM MGRS zone handling
* PDS: Fix up offset support for detached labels
* gdal_merge.py: support per band init values
* ECW: Fix one broken case in configure logic
* RasterLite: Fix crash on 32bit platforms
* NetCDF: Prevent CreateCopy() of complex bands
* HDF4: Fix buffer overflow with GeodeticLatitude
== OGR / Vector ==
* SQLite: TestCapability() returns TRUE for transation support
* DXF: Support polylines in Object Coordinate System
* MIF/ogr2ogr: Fix new problem translating to MIF format
* GeoJSON: Support stdout output via new /vsistdout/ name
* Shapefile: Fixes for winding calculations on read and write
* Postgres: Get field width and precision from SQL queries
The package now has a mysql option in addition to the default pgsql.

GDAL is a translator library for raster geospatial data formats that
is released under an X/MIT style Open Source license. As a library, it
presents a single abstract data model to the calling application for
all supported formats. The related OGR library (which lives within
the GDAL source tree) provides a similar capability for simple
features vector data. It includes roughly 60 format drivers. Current
translators include:
* GeoTIFF (read/write)
* Erdas Imagine (read/write)
* ESRI .BIL (read)
* .aux labelled raw (read/write)
* DTED (read)
* SDTS DEM (read)
* CEOS (read)
* JPEG (read/write)
* PNG (read/write)
* Geosoft GXF (read)
* Arc/Info Binary Grid (read)
