About the Latest Version
Version 3.3 is a major upgrade to Montage. It offers the following important improvements:
- Increased HDU support for multi-part image files.
- Added several additional system flags and notes to notify users of available processing options.
- Fixed several bugs, which has made the software more robust.
- Added more Message Passing Interface (MPI) support.
Please see the Change History for a complete list. This version is used in operations by the Montage on-request Web service. We recommend all users adopt this version. Versions 3.0 and and 3.2 beta will continue to be supported until April 30, 2011.

|Release Version||Release Date||Major Changes|
The following modules have been updated. See the Change History for detailed descriptions.
|Montage v3.0||1/5/2007||The emphasis has been on solidifying
Montage use in a distributed Grid environment to
allow the building of large-scale mosaics from
2MASS, SDSS, and DPOSS.
See detailed Change History for a thorough description of updates.
New modules include:
|Montage v2.2||7/20/2004||Makefiles have been updated and the CFITSIO library modified (see docs/ExternalLibraries.txt for details) to allow the use of 64-bit addressing (files larger than 2 GByte) on LINUX platforms.|
|Montage v2.1||7/1/2004||Changes have been made to several modules. The biggest change, however, is the addition of mTANHdr (and associated changed to mProjectPP) which allow the fast reprojection of non-tangent-plane projections if they can be approximated as distorted TAN images.|
-mAdd no longer allocates the entire output image up front, and so uses even less memory.
-level-only flag has been added to mBgModel.
-New module mShrink added to make scaled versions of an image (e.g. image with pixel scale 5.5 times larger than the original)
-New modules mRadHit and mRadHitExec added to try and remove "radiation hit" type artifacts from original unprojected images by comparing pixel values to local medians.
-New modules mDagTbls and mConcatFit added to aid in GRID computing use of Montage. The first generates a set of tables (lists of images, overlap analysis) for use in setting up a batch processing run. The second combines the output of difference fitting (presumably in this context done via separate threads) into a single table for use by mBgModel.
|Montage v2.0.3||2/4/2004||mAdd has been updated to better manage memory and a fast reprojection (plane-to-plane) module has been added (mProjectPP).|
|Montage v2.0.2||1/13/2004||Fixed several problems with 'boundaries' library (used by mMakeHdr). Also fixed a realloc() bug in mMakeHdr.|
|Montage v2.0.1||11/25/2003||Fixed background matching (specifically mDiff bug) and made various other minor changes.|
|Montage v2.0||9/17/2003||Status file option added to all modules to support GRID (Montage-G DAG) processing. Fixed a couple of bugs in mProject: FITS reading was being done incorrectly (which caused occassional error conditions) and pixel "handedness" was sometime computed incorrectly for CD matrices.|
|Montage v1.7||5/30/03||Corrected defect reports from testing of version 1.6.|
|Montage v1.6||4/24/03||Added support for DSS projection. Corrected defect reports from testing of version 1.5.|
|Montage v1.5||04/01/03||Improved handling of command line parameters, using the Unix command getopt(). Path handling in mImgtbl modified to use filenames only; paths are fed in via arguments to individual modules.|
|Montage v1.4||01/27/03||Background matching improved.|
|Montage v1.3||10/03/02||Workaround for defect in WCS library affecting cylindrical projections; fix for LINUX defect in svc control library.|
|Montage v1.2||9/25/02||Ported to Linux|
|Montage v1.1-beta||7/27/02||Updated pixel overlap to remove repeated (within positional tolerance) points. Otherwise the Girard() calculation gets confused.|
|Montage v1.0||7/01/02||Initial limited release|
