Log message:
texlive: update to TeXLive 2021

General:
* Donald Knuth’s changes for his 2021 tuneup of TeX and Metafont are
  incorporated (https://tug.org/TUGboat/tb42-1/tb130knuth-tuneup21.pdf). They
  are also available on CTAN as the knuth-dist and knuth-local packages. As
  expected, the fixes are for obscure cases and do not affect any behavior in
  practice.
* Except in original TeX: if \tracinglostchars is set to 3 or more, missing
  characters will result in an error, not just a message in the log file, and
  the missing character code will be shown in hex.
* Except in original TeX: a new integer parameter \tracingstacklevels, if
  positive, and \tracingmacros is also positive, causes a prefix indicating the
  macro expansion depth to be output on each relevant log line (e.g., ~.. at
  depth 2). Also, macro logging is truncated at a depth ≥ the parameter value.

Aleph: The Aleph-based LaTeX format, named lamed, has been removed. The aleph
  binary itself is still included and supported.

LuaTeX:
* Lua 5.3.6.
* Callback for nesting level used in \tracingmacros, as generalized variant
  of the new \tracingstacklevels.
* Mark math glyphs as protected to prevent processing as text.
* Removed width/ic compensation for traditional math code path.

MetaPost:
* SOURCE_DATE_EPOCH environment variable support for reproducible output.
* Avoid wrong final % in mpto.
* Document -T option, other fixes to manual.
* Value of epsilon changed in binary and decimal modes, so mp_solve_rising_cubic
  works as expected.

pdfTeX:
* New primitives \pdfrunninglinkoff and \pdfrunninglinkon; e.g., for
  disabling generation of links in headers and footers.
* Warn instead of aborting when “\pdfendlink ended up in different nesting
  level than \pdfstartlink”.
* Dump \pdfglyphtounicode assignments in fmt file.
* Source: poppler support removed, as it was too hard to keep in sync with
  upstream. In native TL, pdfTeX has always used libs/xpdf, which is cut-down
  and adapted code from xpdf.

XeTeX: Fixes for math kerning.

Dvipdfmx:
* Ghostscript is now invoked safely by default; to override (assuming all
  input files are trusted), use -i dvipdfmx-unsafe.cfg. To use PSTricks with
  XeTeX, this is required, as in:
   xetex -output-driver="xdvipdfmx -i dvipdfmx-unsafe.cfg -q -E" ...
* If an image file is not found, exit with bad status.
* Extended special syntax for color support.
* Specials for manipulating ExtGState.
* Compatibility specials pdfcolorstack and pdffontattr.
* Experimental support for dviluatex’s extended fnt_def.
* Support new feature of virtual font to fallback Japanese font definition.

Dvips:
* Default PostScript document title is now the basename of the input file,
  and can be overridden with the new option -title.
* If an .eps or other image file is not found, exit with bad status.
* Support new feature of virtual font to fallback Japanese font definition.

Log message:
texlive: update to 2020

General:
* The \input primitive in all TeX engines, including tex, now also accepts a
  group-delimited filename argument, as a system-dependent extension. The usage
  with a standard space/token-delimited filename is completely unchanged. The
  group-delimited argument was previously implemented in LuaTeX; now it is available
  in all engines. ASCII double quote characters (") are removed from the \ 
filename,
  but it is otherwise left unchanged after tokenization. This does not currently
  affect LaTeX’s \input command, as that is a macro redefinition of the standard
  \input primitive.
* New option –cnf-line for kpsewhich, tex, mf, and all other engines, to support
  arbitrary configuration settings on the command line.
* The addition of various primitives to various engines in this and previous years
  is intended to result in a common set of functionality available across
  all engines.

epTeX, eupTeX: New primitives \Uchar, \Ucharcat, \current(x)spacingmode, \ifincsname;
 revise \fontchar?? and \iffontchar. For eupTeX only: \currentcjktoken.

LuaTeX: Integration with HarfBuzz library, available as new engines luahbtex
 (used for lualatex) and luajithbtex. New primitives: \eTeXgluestretchorder,
 \eTeXglueshrinkorder.

pdfTeX: New primitive \pdfmajorversion; this merely changes the version number
 in the PDF output; it has no effect on any PDF content. \pdfximage and similar
 now search for image files in the same way as \openin.

pTeX: New primitives \ifjfont, \iftfont. Also in epTeX, upTeX, eupTeX.

XeTeX: Fixes for \Umathchardef, \XeTeXinterchartoks, \pdfsavepos.

Dvips: Output encodings for bitmap fonts, for better copy/paste capabilities.

Log message:
texlive: updated to 20190410

20190410:

Kpathsea: More consistent brace expansion and path splitting; new variable \ 
TEXMFDOTDIR instead of hard-coded . in paths allows for easily searching \ 
additional or sub-directories (see comments in texmf.cnf).

epTEX, eupTEX: New primitives \readpapersizespecial and \expanded.

LuaTEX: Lua 5.3 now used, with concomitant arithmetic and interface changes. The \ 
homegrown library pplib is used to read pdf files, thus eliminating the \ 
dependency on poppler (and the need for C++); Lua interface changed accordingly.

MetaPost: r-mpost command name recognized as an alias for invocation with the \ 
–restricted option, and added to the list of restricted commands available by \ 
default. Minimum precision now 2 for decimal and binary mode. Binary mode no \ 
longer available in MPlib but still available in standalone MetaPost.

pdfTEX: New primitive \expanded; if new primitive parameter \pdfomitcharset is \ 
set to 1, the /CharSet string omitted from the PDF output, since it cannot \ 
feasibly be guaranteed correct, as required by PDF/A-2 and PDF/A-3.

XeTEX: New primitives \expanded, \creationdate, \elapsedtime, \filedump, \ 
\filemoddate, \filesize, \resettimer, \normaldeviate, \uniformdeviate, \ 
\randomseed; extend \Ucharcat to produce active characters.

tlmgr: Support curl as a download program; use lz4 and gzip before xz for local \ 
backups, if available; prefer system-provided binaries over binaries provided \ 
with TEX Live for compressor and download programs, unless the environment \ 
variable TEXLIVE_PREFER_OWN is set.

install-tl: New option -gui (with no argument) is the default on Windows and \ 
Macs, and invokes a new Tcl/TK GUI (see sections 1.3 and 3.1.6).

Utilities:

cwebbin (https://ctan.org/pkg/cwebbin) is now the CWEB implementation in TEX \ 
Live, with support for more language dialects, and including the ctwill program \ 
to make mini-indexes.
chkdvifont: report font information from DVI files, also from tfm/ofm, vf, gf, pk.
dvispc: make a DVI file page-independent with respect to specials.
MacTEX: x86_64-darwin now supports 10.12 and higher (Sierra, High Sierra, \ 
Mojave); x86_64-darwinlegacy still supports 10.6 and newer. The spell checker \ 
Excalibur is no longer included, since it requires 32-bit support.

Platforms: removed sparc-solaris.
