Adobe Labs is the domain of public program testing for Adobe, allowing us glimpses at programs prior to release. Both Lightroom 1 and 2 were available there, and now Camera Raw 4.6 and the associated DNG converter are available from there to download. This is a release candidate version, meaning that it has been internally tested, but needs more testing in the public domain before being released as an automatic update.
New cameras fully supported by this version include Fuji Finepix IS Pro, Nikon D700, Nikon D90 and the Nikon Coolpix 6000. Preliminary (i.e. uncertified) support is provided for Canon Rebel XS, 50D, Olympus SP-565 UZ, Sony A900 and Sigma DP1 (the DP1 support is not finalised).
You can read more from Product Manager Tom Hogarty over at Lightroom Journal, where he made the announcement.
