-**Some plans for changes to be incorporated in the next major release are:** 
- 
-  * ipp9 testing (Chris) 
-  * virtual trunk to compile (Cormac) 
-    * Add datasim, dirlist, polconvert, autozoom 
-  * vex2difx testing for all use cases (everyone) 
-  * <del> GMVA difx2fits merging of compatible setups (Helge/​Walter) </​del>​ 
-  * VDIF testing (Helge) 
-  * <del> bug resolution for Alessandra and Gabriele (Walter) </​del>​ 
-  * <del> native mark6 mode working and tested (Walter) </​del>​ 
-  * Record delay model used in FITS file (Walter). 
-  * Supporting >5 EOPs. Test and confirm AIPS support. (Walter, AIPS team) 
-  * Changelog updates (Everybody) 
-  * Test, test, test (Everybody) 
-  * Documentation:​ 
-    * Datasim, autozoom (Zheng) 
-    * mark6 (Walter/​Helge) 
- 
- 
-==== Plans for future release 2.6 ==== 
- 
-  * Production mark6 support. 
-  * vex2 support 
-  * cloud computing 
-    * real-time e-VLBI 
-  * Filterbank channelisation 
-  * Doing sideband inversion at unpack rather than FFT stage 
-  * Separate mk5daemon from mk6daemon (Helge) 
- 
- 
-==== DiFX 2.3 ==== 
- 
-=== Bug fixes === 
- 
-  * mpifxcorr: Datasteam buffer send size now calculated correctly for complex sampled data 
-  * mpifxcorr: Avoid very rare bug where combination of geometric delay and data commencing mid-subint meant one invalid FFT might be computed 
-  * mpifxcorr: multicast weights are now computed correctly for mixed-sideband correlation 
-  * mpifxcorr: fixed bug where some autocorrelations were not saved in a mixed-sideband correlation 
-  * mpifxcorr: fixed bug where send size could be computed incorrectly by 1-2 bytes for Mark4/​VLBA/​Mark5B/​VDIF formats, potentially resulting in very small amounts of data loss 
- 
-=== New features === 
- 
-  * mpifxcorr: LO offsets are now corrected in the time domain when fringe rotation is also done in the time domain (the usual mode), allowing considerably larger LO offsets without decorrelation 
-  * mpifxcorr: Working polarization dependent delay and phase offsets 
-  * mpifxcorr: Experimental linear2circular conversion 
-  * mpifxcorr: Complex Double sideband (RDBE/​Xcube) sampling support 
-  * mpifxcorr: new file/mk5 based vdif/mark5b datastream (faster and more robust) 
-  * utilities: some new command line tools for mk5b and vdof files (vsum, mk5bsum, vmux, mk5bfix) 
-  * all packages: mk5 support for mark5a/b with sdk9 
-  * new options for passing calibration (Walter B: memo forthcoming)
