Changes in arb 2.19.0:

• Significant improvements to the implementation of Platt's algorithm for computing Riemann zeta function zeros at large height (contributed by p15-git-acc).
• Better criterion for selecting asymptotic expansion of incomplete gamma function (contributed by p15-git-acc).
• Multithreaded acb_dft for power-of-two lengths (contributed by p15-git-acc).
• Added acb_csc_pi, arb_csc_pi (contributed by p15-git-acc).
• Fixed segfault in acb_mat_eig_simple_rump when called with L non-NULL and R NULL (contributed by p15-git-acc).
• Fixed bug in acb_real_abs (contributed by Joel Dahne).
• Changed several functions to more consistently return infinities instead of NaNs where reasonable (contributed by p15-git-acc).
• Added Fransen-Robinson as an integral example (contributed by p15-git-acc).
• Cleaned up makefile (contributed by p15-git-acc).
• Fixed several typos and some omitted functions in the documentation (contributed by Joel-Dahne, p15-git-acc).

Changes in bliss:

• Switch to using the sagemath sources
• Drop -error patch; nobody else uses it and it changes the contract

Changes in L-function:

• Change order of #includes to fix FTBFS with g++ 11

Changes in sagemath:

• Yet another attempt to fix the upgrade path

The sympol build is a simple rebuild due to the bliss update.
