# CSOUND VERSION 6.11 RELEASE NOTES
There has been a great amount of internal reorganisation, which should
not affect most users. Some components are now independently managed
and will eventually be installable via a new package manager. The
realtime option is now considered stable and has the "experimental"
tag removed. Special support for the Bela platform has been introduced.
There have been more steps towards completing the
arithmetic operations involving a-arrays.
Note that changes to GEN01 and diskin2 may not be backward compatible
if a non zero value is given for the format.
-- The Developers
## USER-LEVEL CHANGES
### New opcodes
- loscilphs, loscil3phs are like loscil but return the phase in
addition to the audio.
- More arithmetic between a-rate arrays and a-rate values; this
completes the arithmetic where one or more argument is an audio
array.
- balance2 is like balance but scales the output at a-rate, rather than
k-rate.
### New Gen and Macros
-
### Orchestra
-
### Score
- Characters following a \ in a score string are treated as escaped, so
\n is a newline rather than two characters. It handles escaped a,
b, f, n, r, t and v. Other characters following a \ ignore the backslash.
### Options
-
### Modified Opcodes and Gens
- print, printk2 now take an additional optional argument which if
non-zero causes the k-variable name to be printed as well as the value.
- getrow, setrow, getcol, and setcol can now act on i-rate arrays.
- diskin2 was incorrectly described in the manual with respect to the
iformat parameter. Now if iformat is zero the file is expected to
have an audio header; if in the range 1-10 (rather than 0-9 as
before) then it is opened as raw with the specified sample format.
***THIS MAY BE INCOMPATIBLE***. For most users the value of zero will
be correct.
- GEN01 now uses format 0 to get the file type from the header; any
other value indicates a raw file. ***THIS MAY BE INCOMPATIBLE***. For
most users the value of zero will be correct.
- GEN01 was incorrectly documented with respect to the format
argument. There are 9 raw formats whereas the earlier manual stated 6.
- Small change in slicearray should allow it to be used in functional
form in most cases.
- The family of opcodes tb0 to tb15 and their initialisation opcodes
tb0_init to tb15_init are deprecated as multi-argument functions are
allowed.
- The mode filter now does not allow a frequency in the unstable region.
- In scanu and xscanu the value of kpos is supposed to be in the range
[0,1]. This is now enforced by treating all negative values as 0 and all
values bigger than 1 as 1.
### Utilities
- src_conv is now available on Windows and MacOS
### Frontends
- Belacsound: a new frontend specific for the Bela platform is introduced
in this version.
- CsoundQt:
### General Usage
## Bugs Fixed
- linen was reworked to allow for long durations and overlaps.
- Resetting csound caused a crash if Lua opcodes were used; fixed.
- The poscil family of opcodes could give incorrect results if used in
multi-core orchestras AND another instrument changed the f-table.
This is now corrected.
- Use of out with an audio array did not check that the array
dimension was not greater than the number of channels, which caused
a crash. It is now checked and truncated if too large with a
warning.
- Bug in stereo versions of loscil introduced distortion; now fixed.
- Fencepost error in phs fixed.
- gen49 read deleted memory if the file was not found; fixed
- Loading of LADSPA plugins when relying on search paths was wrong and
mangled the name; now fixed.
## SYSTEM LEVEL CHANGES
- OPCODE6DIR{64} now can contain a colon-separated list of directories.
### System Changes
- The somewhat curious distinction between k-rate and a-rate perf-time
has been removed throughput, so only threads 1, 2 and 3 are used,
the s-type output is not used, and some x-type inputs have
been changed for direct polymorphism. This only matters for opcode
writers as the s, and x codes and threads 4, 5, 6 and 7 will be
removed in a while.
### Translations
- As ever the French translations are complete.
### API
- No changes to the API
### Platform Specific
- WebAudio: from this release onwards, the Csound port for the web platforms has been
merged into a single package henceforth called 'WebAudio Csound'. There are many internal
changes to this, the AudioWorklet interface is employed wherever supported, with a fallback to
ScriptProcessorNode elsewhere. Csound is also available in the form of independent Nodes,
in addition to the original CsoundObj API. The csound.js frontend, originally designed for
PNaCl Csound, is also ported to WebAudio Csound, following the deprecation of that
port of Csound.
