20220130:
- An arc() function (to draw an arc) with a width (thickness)
parameter has been added to the draw.s7i library. Many thanks to
Zachary Menzies for pointing out that it was missing.
- The new library tiff.s7i has been added. This library supports the
TIFF image file format.
- The new library ccittfax.s7i has been added. This library supports
CCITT fax decoding as it is used in TIFF files.
- The library zip.s7i has been improved to support reading zip64
archives.
- A chapter about the type 'process' has been added to the manual.
The chapter about case statements and other chapters of the manual
have been improved as well.
- Bit streams have been introduced and the huffman decoding has been
improved. The run-time to extract a gzipped Seed7 archive with tar7
has been reduced to 46% (measured with gcc and valgrind). Other
usages of the inflate algorithm (PNG, ZIP, etc.) also benefit from
the improvements.
- The compiler has been improved to:
- Optimize overflow checks away for shift operations.
- Optimize index checks for string operations.
- Write an error message if an unsupported option is used.
- Inline the string tail function.
- Use parentheses to reduce C compiler warnings.
- Improve optimizations of the bytes2Int() function.
- Improve checking of division by zero.
- The statistics of the Seed7 compiler (s7c.sd7) has been improved
to count inlined functions, optimized index checks and optimized
overflow checks.
- In bitdata.s7i, the types bitStream, lsbBitStream and msbBitStream
have been introduced. These types support the functions getBit(),
getBits(), peekBits(), skipBits() and gets().
- In bitdata.s7i, the functions openLsbBitStream() and
openMsbBitStream() have been introduced to create lsbBitStream
and msbBitStream values. With these functions, bit streams can be
created with a file or a string as data source.
- In bitdata.s7i the functions getBitLsb(), getBitsLsb(),
peekBitsLsb(), skipBitsLsb(), getBitMsb(), getBitsMsb(),
peekBitsMsb() and skipBitsMsb() with string als parameters are
deprecated now. The functions with the types lsbBitStream and
msbBitStream should be used instead.
- In huffman.s7i the functions getHuffmanSymbolMsb(string, ...) and
getHuffmanSymbolLsb(string, ...) are deprecated. The functions
getHuffmanSymbol(msbBitStream, ...) and
getHuffmanSymbol(lsbBitStream, ...) should be used instead.
- Tests for getBit(), getBits(), peekBits(), skipBits() and gets()
have been added to chkbitdata.sd7. This refers to tests with
lsbBitStream and msbBitStream.
- The program chk_all.sd7 has been adjusted to the changes in
chkbitdata.sd7.
- The functions in inflate.s7i have been improved to use lsbBitStream
as parameter instead of the previous combination of string, bytePos
and bitPos.
- The library inflatefile.s7i has been removed. The functions from
inflate.s7i can be used instead.
- The library cpio.s7i has been improved to check if a CPIO header
is the correct size.
- The library bytedata.s7i has been improved to raise RANGE_ERROR
if an empty byte string is converted to integer or bigInteger.
- The library gzip.s7i has been improved to use lsbBitStream and the
new functions from inflate.s7i.
- The library imagefile.s7i has been improved to support TIFF images.
- The library jpeg.s7i has been improved to use
getHuffmanSymbol(msbBitStream) instead of
getHuffmanSymbolMsb(stri, bytePos, bitPos, ...).
- The library lzw.s7i has been improved to support the functions
lzwDecompress(lsbBitStream, ...), lzwDecompress(msbBitStream, ...),
lzwDecompressEarlyChange(msbBitStream, codeSize),
lzwDecompressEarlyChange(msbBitStream, codeSize, requestedLength)
and lzwDecompressMsbEarlyChange(string, codeSize, requestedLength).
- The files bitdata.s7i, gzip.s7i, inflate.s7i, jpeg.s7i, zstd.s7i
and chkbitdata.sd7 have been refactored to avoid 'bitStream' as
variable name. The name 'bitStream' is now used as interface type
in bitdata.s7i.
- The Seed7 compiler has been improved in comp/arr_act.s7i,
comp/bin_act.s7i, comp/bst_act.s7i, comp/const.s7i,
comp/flt_act.s7i, comp/int_act.s7i, comp/intrange.s7i,
comp/literal.s7i, comp/prc_act.s7i, comp/rfl_act.s7i,
comp/set_act.s7i, comp/stat.s7i, comp/str_act.s7i and s7c.sd7.
- Checks for bytes(), bytes2Int(), the right shift operator and
division by zero have been added to chkint.sd7.
- Checks for bin64 shift operations have been added to chkbin.sd7.
- Checks for index access to an empty array have been added to
chkarr.sd7.
- Checks for bytes2BigInt() have been added to chkbig.sd7.
- In array.s7i the declaration of the times operator has been
simplified.
- The program pv7.sd7 has been improved to support TIFF files.
- Casts have been added to dll_win.c and libpath.c to reduce C
compiler warnings.
- In error.c the error message for a failed declaration has been
improved.
- In str_rtl.c the performance of strHeadSlice() has been improved.
- Unused variables have been removed in several files of the
compiler.
- In int_rtl.c the functions intBytesBe2Int(), intBytesBe2UInt(),
intBytesLe2Int() and intBytesLe2UInt() have been changed to raise
RANGE_ERROR if the string is empty.
- In big_rtl.c and big_gmp.c the functions bigFromByteBufferBe()
and bigFromByteBufferLe() have been changed to raise RANGE_ERROR
if the size is zero (the buffer is empty).
- The files drw_win.c, drw_x11.c, drw_drv.h, drwlib.c, drwlib.h and
primitiv.c have been changed to support the action DRW_PFARC.
- Definitions for the function XSetLineAttributes() have been added
to fwd_x11.c and x11_x.h.
- In the program chkccomp.c the detection of the division by zero
behavior and the remainder by zero behavior has been improved.
- Documentation comments have been improved in bstring.s7i,
bytedata.s7i, bitdata.s7i, null_file.s7i, process.s7i, strifile.s7i
and biglib.c.
Persepolis is a download manager and GUI for Aria2 which is written
in Python using Qt and other components. Some functionality had been
reimplemented to avoid pulling needless or heavy dependencies.

This version is just a copyright-year update. I'm taking advantage
to follow Daniel Engberg's advice to use the upstream tarballs
rather than GitHub tarballs, even though the upstream tarballs
are, IMO, terrible.
While here, pull in a patch I wrote to avoid crashes on startup.
This port is copied from dns/py-dnspython. Assign to original author.
This port is created to streamline the updated version of 2.x release
for using with other ports.
dnspython is a DNS toolkit for Python. It supports almost all record
types. It can be used for queries, zone transfers, and dynamic
updates. It supports TSIG authenticated messages and EDNS0.
dnspython provides both high and low level access to DNS. The high
level classes perform queries for data of a given name, type, and
class, and return an answer set. The low level classes allow direct
manipulation of DNS zones, messages, names, and records.
This is 1.x version of the port which supports python 2.7
