It's time to work on the release tour for Sage 9.5:
If you don't have an account that allows you to edit the wiki, please feel free to just post additions as a reply here; I can add them to the page.

Hello Matthias,

As part of my GSoC 2021 project (#31560), there was some significant changes made to the ring of modular forms that are going to be part of Sage 9.5:
  • sage/modular/modform/find_generators.py was renamed into sage/modular/modform/ring.py (#31559);
  • The class ModularFormsRing (located in sage/modular/modform/ring.py)  now follows the Parent/Element structure (#31559);
  • A conversion bug between spaces of modular forms was fixed (#32168);
  • Rings of quasimodular forms for a given congruence subgroups were implemented (#31512);
  • One can now convert a modular form ring element and a quasimodular form ring element to a polynomial in the generator of the ring (#32135, #32336)
  • Derivatives of modular forms and quasimodular forms were implemented (#32343, #32357).
I also blogged about most of these changes here. Don't hesitate if you need further informations.

Best,

David A.

    Something about prinecount and related functions should be added. I'll do this.

    OK, I've added a bit, but the TOC does not get updated, for some
    reason (Number theory should have 4 items, not 2).

    no idea what this means, to add a section. Is `== Number theory ==` a section?
    What kind of magic is supposed to count the entries there?

    Yes, == and === is the wiki markup for sections

    so the section is already there. Why does the TOC only list 2 entries there?

    in the TOC there is

    4. Number theory
    1. Elliptic curves and isogenies
    2. Modular and quasimodular forms
    5. ...

    but it should be

    4. Number theory
    1. Elliptic curves and isogenies
    2. Modular and quasimodular forms
    3. (about binary forms)
    4. (about prime_pi etc)
    5. ...

    No idea how

    1. Elliptic curves and isogenies
    2. Modular and quasimodular forms
    got there in the TOC...

    You added 2 bullet points after the existing 2 bullet points at the top of section 4 "Number Theory".
    After the 4 bullet points, there are 2 subsections. These are what appears in the TOC.

    Now that the updated Sage documentation is online at https://doc.sagemath.org/html/en/index.html (thanks, Harald!), we can add links to the reference manual.
