Version history:

0.1.3:
- CHANGE: exchanged #defines for templates in vector calculation loops
- FIX: bug for binary operations of complex vasps
- ADD: implemented (factor-4) loop unrolling for vector calculation loops
- CHANGE: completely restructured vector optimization and introduced multi-dimensional multi-layered functionality
- ADD: vasp.size variants: attribute "zero" (default: true) - whether new samples shall be zeroed
- ADD: vasp.sum? to get sum of sample values
- ADD: all objects: attribute "defer" to queue outgoing vasps  - to avoid stack faults for message loops
- CHANGE: enable attributes "detach" and "prior" also for non-threaded builds to ensure patch compatibility
- FIX: vasp.size - flext bug for @keep=1
- FIX: vasp.imm - bug with memory reservation length
- ADD: vasp.imm - attribute "zero" (default: true) - whether array should be cleared 
- FIX: Max/MSP - freeing immediate buffers with overdrive is bogus -> using queued flext timer
- FIX: Bug in clearing vasp references
- CHANGE: changed behavior of vasp.spit on uneven vector counts
		[vasp a b c( -> [vasp.spit 2] now outputs a(outlet 2), b(outlet 1), c(outlet 2), bang(outlet 3)
- REMOVE: eliminated [vasp.cconj] as an object as it can easily be replaced by an abstraction

0.1.2:
- FIX: bug in vasp.frames* ... wrong argument
- FIX: another bug in resize of immediate buffers
- CHANGE: immediates will be initialized to zero, also upon resize to a larger size (by default, later make this optional)
- ADD: attributes for all basic parameters: ref,to,arg, update,detach,prior (loglvl,argchk,unit later)
- ADD: vasp.channel,vasp.vector - attribute "index"
- ADD: vasp.frames,vasp.frames+,vasp.offset,vasp.offset+,vasp.size,vasp.size+,vasp.imm - attribute "frames"

- ADD: vasp.offset=,vasp.frames= - attributes "dir","slope"
- CHANGE: update m_method_ virtual functions of same objects
- FIX: immediate vasp garbage collection is now done in separate thread
- ADD: vasp.size... objects: attribute "keep" determines whether buffer content should be preserved (default = 1)

- FIX: immediate vasps can not have frames > size
- FIX: immediate garbage collection was not triggered in threaded build
- FIX: changed forgotten standard ASSERT to FLEXT_ASSERT (thanks to Frank Barknecht)

0.1.1:

- CHANGE: warn - but don't stop - on large FFT prime factors
- FIX: vasp.radd and vasp.rpow had wrong argument initialization
- FIX: mixfft is not thread-safe... introduced thread mutex for it
- FIX: vasp.shift: shift argument was modulo frame count... why?

0.0.8:
- CHANGE: vasp.radio got right outlet for non-radio messages
- ADD: thread yield for all simple vasp objects

- NEW: vasp.window, vasp.*window, vasp.!window, vasp.*!window, vasp.xwindow, vasp.*xwindow
- REMOVE: vasp.bevel, vasp.!bevel... obsolete due to new vasp.window objects
- REMOVE: vasp.noradio (vasp.!radio)... can easily be an abstraction of vasp.radio
- ADD: minimum length parameter for immediate vasps
- NEW: vasp.channel? (vasp.c?), vasp.channel (vasp.c) for set/query of buffer channel
- CHANGE: env - reversed time/value pairs to value/time pairs
- FIX: vasp.! with length arg outputs its reference on bang
- FIX: on set message check for invalid vasps
- FIX: reintroduce test for invalid buffer names (why was it commented out?)
- FIX: fixe several bugs in vasp.offset= and vasp.frames=
- CHANGE: allow size 0 (is default) for immediate vasps

0.0.7:
- CHANGE: vasp.m is now called vasp.multi by default
- CHANGE: vasp.sync and vasp.multi now have a default argument = 2
- FIX: vasp.phasor - period length now 1 instead of 2 PI

- ADD: shortcuts for vasp.frames,vasp.frames+,vasp.frames? -> vasp.f,vasp.f+,vasp.f?
- CHANGE: changed vasp.offs,vasp.offs+,vasp.offs? to vasp.offset,vasp.offset+,vasp.offset?
