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
* In order for pftop to be built successfully with newer PF
versions (> 4.1), additional patches are necessary which were taken
from OpenBSD's ports as seen in PR pkg/44339
* Pftop compiled for another PF version will not work (properly),
so to avoid any problems we must depend on the OS version

9.6.3
* BIND now builds with threads disabled in versions of NetBSD earlier
than 5.0 and with pthreads enabled by default in NetBSD versions
5.0 and higher. Also removes support for unproven-pthreads,
mit-pthreads and ptl2. [RT #19203]
* HPUX now correctly defaults to using /dev/poll, which should
increase performance. [RT #21919]
* If named is running as a threaded application, after an "rndc stop"
command has been issued, other inbound TCP requests can cause named
to hang and never complete shutdown. [RT #22108]
* When performing a GSS-TSIG signed dynamic zone update, memory could
be leaked. This causes an unclean shutdown and may affect
long-running servers. [RT #22573]
* A bug in NetBSD and FreeBSD kernels with SO_ACCEPTFILTER enabled
allows for a TCP DoS attack. Until there is a kernel fix, ISC is
disabling SO_ACCEPTFILTER support in BIND. [RT #22589]
* Corrected a defect where a combination of dynamic updates and zone
transfers incorrectly locked the in-memory zone database, causing
named to freeze. [RT #22614]
* Don't run MX checks (check-mx) when the MX record points to ".".
[RT #22645]
* DST key reference counts can now be incremented via dst_key_attach.
[RT #22672]
* isc_mutex_init_errcheck() in phtreads/mutex.c failed to destroy
attr. [RT #22766]
* The Kerberos realm was being truncated when being pulled from the
the host prinicipal, make krb5-self updates fail. [RT #22770]
* named failed to preserve the case of domain names in RDATA which is
not compressible when writing master files. [RT #22863]
* There was a bug in how the clients-per-query code worked with some
query patterns. This could result, in rare circumstances, in having
all the client query slots filled with queries for the same DNS
label, essentially ignoring the max-clients-per-query setting. [RT
#22972]
* More strict dependency reflect gemspec's description.
*Rails 3.0.4 (unreleased)*
* Added deprecation warning for has_and_belongs_to_many associations where the join table has
additional attributes other than the keys. Access to these attributes is removed in 3.1.
Please use has_many :through instead. [Jon Leighton]
*Rails 3.0.3 (November 16, 2010)*
* Support find by class like this: Post.where(:name => Post)
*Rails 3.0.2 (November 15, 2010)*
* Dramatic speed increase (see: http://engineering.attinteractive.com/2010/10/arel-two-point-ohhhhh-yaaaaaa/) [Aaron Patterson]
* reorder is deprecated in favor of except(:order).order(...) [Santiago Pastorino]
* except is now AR public API
Model.order('name').except(:order).order('salary')
generates:
SELECT * FROM models ORDER BY salary
[Santiago Pastorino]
* The following code:
Model.limit(10).scoping { Model.count }
now generates the following SQL:
SELECT COUNT(*) FROM models LIMIT 10
This may not return what you want. Instead, you may with to do something
like this:
Model.limit(10).scoping { Model.all.size }
[Aaron Patterson]
* More strict dependency reflect gemspec's description.
*Rails 3.0.3 (November 16, 2010)*
* When ActiveRecord::Base objects are sent to predicate methods, the id of
the object should be sent to ARel, not the ActiveRecord::Base object.
* :constraints routing should only do sanity checks against regular
expressions. String arguments are OK.
*Rails 3.0.2 (November 15, 2010)*
* The helper number_to_currency accepts a new :negative_format option to be
able to configure how to render negative amounts. [Don Wilson]
