Thanks to everyone who contributed to this release.

Bugs fixed in version 0.82

dict - under some circumstances it was possible to add duplicate keys to a dict
file delete - -force and -- were handled incorrectly
aio: ssl - fix eof detection with openssl3
getref and setref - now accept fully qualified references
unset - don’t return a result with -nocomplain
Garbage collection - sometimes GC was overly zealous
regexp - builtin regexp fix for end of word check
dict with - now correctly returns the script result
Unicode ranges are closed intervals. This affected the character class of the end character of each range.

Features and improvements added in version 0.82

aio gets - improve behaviour for non-blocking streams
aio TIP 603 - implement stat of an open file handle
aio socket pty - filename is now available
Included sqlite updated to version 3.38.0
redis extension - enable TCP_KEEPALIVE, add support for -type and -async
try - add support for trap
oo constructor is now more flexible (possible incompatibility with 0.81)
socket - add support for -async
Updated linenoise now has support for word forward, word backward
Updated Unicode to 14.0.0
file normalize - now supported on Windows
aio copyto - performance improvement for large copies
Memory allocator is now replaceable
info frame is now more Tcl compatible (incompatibility with 0.81)
New timerate command for improved benchmarking - largely compatible with TIP 527
vwait - add support for -signal for improved handling of signals in the event loop
clock millis and clock micros - now use monotonic time if possible (not affected by system time changes)
ensemble and namespace ensemble simplify creation of ensemble commands

Possible incompatibilities in version 0.82

New approach to oo constructor means some existing code may need to be altered
info frame now returns a dict rather than a list and can access non-proc frames. stacktrace will continue to work and should be preferred when retrieving a live stack trace
New ABI version means that compiled extensions will need to be rebuilt to work with this version
configure now defaults to --full
