_Alternatively, the first time I've manually written notes in months_

What's New

* We now have an element for counting overlapping occurances of one value in another. It's `øO`, and was added by tobyck in PR 1357.

What's Changed

* There are new overloads for `Ṡ` for numbers and strings. This type handling addition brought to you by tobyck in PR 1359.
* Powerset now returns a list of strings when given a string. This was done by chunkybanana in PR 1356.
* Shuffle (`Þ℅`) now keeps strings as strings thanks to Steffan153 in PR 1366.
* `İ` no longer includes the initial value thanks to Steffan153 in PR 1362.
* The documentation for `↔` and `İ` has been updated by Steffan153 to reflect this change in PR 1361.
* The behaviour of `Ȧ` has been improved by Steffan153 in PR 1371 when given a list as one of either `rhs` or `other`.
* The online interpreter will no longer include certain flags in CGCC submissions thanks to PR 1360 by Steffan153.

What's Changed
- `øḋ` (to float string) now vectorises on lists thanks to Lyxal (1330)
- `ḋ` (divmod) works when dividing by 0 thanks to Lyxal (1338)
- Sorting 0 now works thanks to Lyxal (1336)
- Parsing an integer from a string now works in all cases thanks to Lyxal (1347)

Also, sympy's `nsimplify` function transforms a python value into a sympy value. You'd expect it to transform a string representing an integer into a sympy value representing that integer, right?

Wrong.

python
>>> sympy.nsimplify('4678')
13841287201*2**(7/16)*3**(7/40)*5**(51/80)*7**(1/8)/17280000


And yes, that does resolve to 4678, but why sympy does this I have no idea.

Anyway, using `rational=True` seems to solve the problem (we hope). Fixing the last of the previous list exposed many new bugs - things also using `sympy.nsimplify` on strings. Lyxal went through and patched all of these (1350)

New stuff
You can now close multiple structures at once! Stuff like `ƛ[3|5];` no longer requires the closing `]`, as the closing delimiters `])};` close structures up to and including the one they match. For example, with `5(ƛ[3|5;` the `;` closes the `[` and the `ƛ`, but not the `(` as it's reached `ƛ` which it matches.
Thanks to Steffan153 for this (1340)

Online interpreter
Some autocompletes now work correctly thanks to Lyxal (1339)

**Full Changelog**: https://github.com/Vyxal/Vyxal/compare/v2.15.0...v2.15.1

_Alternatively, that one time I made a release with notes I didn't write (chunkybanana did)_

We finally fixed all the tests!!!


Online interpreter

To the digraph tooling from last week, we've added a different way of adding elements: words! For example, if you type `sum` in the code box then press <kbd>tab</kbd>, you get `∑`! This was done by chunkybanana and Steffan153 (1278). Additionally, Lyxal added some more completions to the existing digraphs. (1280)

Also, pressing tab after numbers or strings of lowercase letters compresses them thanks to Steffan (1321, 1323)

Bugs

- Indexing into a string now works correctly when the index is larger than the string, thanks to Lyxal (1288)
- You can now halve irrationals e.g. √2 thanks to Lyxal (1289)
- A variety of bizzare bugs caused by incorrect boolification of lazylists has been fixed thanks to Steffan (1272)
- `ṅ` now vectorises on lists of lazylists thansk to Lyxal (1305)
- The arrow parsing elements now work properly thanks to Lyxal (1302)
- The codepage parsing builtin now vectorises over strings correctly thanks to Lyxal (1304)
- `Ṁ` now inserts at negative indices correctly thanks to Lyxal (1293)
- Nested modifiers now have sensible arity thanks to Steffan153 (1309)

Changes
- `ÞK` and `ÞS` now return lists of numbers given lists thanks to Lyxal (1297, 1303)
- `İ` now converts indices to integers first thanks to Lyxal (1298)
- Prepending a list to a list now does *not* concatenate them thanks to Lyxal (1294)
- `↔` now works on infinite lists thanks to chunkybanana (1315)
- Various multiset builtins (`Þ∨`,`Þ∩`,`Þ∪`) now behave differently on varied types thanks to Lyxal (1314, 1316, 1317)
- Splitting and keeping delimiters (`Ẇ`) now works sensibly on fractions thanks to Lyxal (1311)

Internal
- Converting a non-integer to a digit list now doesn't turn it into a decimal thanks to Lyxal (1296)
- We got rid of the `/oeis` page, which wasn't working anyway thanks to chunkybanana (1310)
- Lyxal fixed some failing test cases for `Ǒ`, `∪`, `øḞ`, `øṄ`, `Þ⊍`, and `€` (1301, 1299, 1295, 1312, 1313, 1318)
- The final testcase (`Þ÷`) was fixed by Steffan153 (1319)
- Some variable scoping issues were fixed by cgccuser (1281)
- While loops were pushing two context variables and only popping one. This was fixed by Steffan153 (1325)


What's new

- `ÞŻ` sorts a multidimensional list at every level, thanks to chunkybanana (1292)
- `Ṫ` now, when given a number, pushes 1 under it thanks to Lyxal (1291)
- `øA` now converts letters to numbers and vice versa thanks to chunkybanana (1290)
- You can now override the inputs with `¨S` and reset them with `¨R` thanks to Steffan153 (1308)

**Full Changelog**: https://github.com/Vyxal/Vyxal/compare/v2.14.2...v2.15.0

The great bug fix has somewhat come to a halt, as what remains is mostly typing ambiguities we're unsure how to handle. Also, the online interpreter has been substantially upgraded, now supporting several new functionalities.

Changes
- `kP` (printable ASCII) is now in order, and `kQ` is printable ASCII with a space [thanks to](https://github.com/Vyxal/Vyxal/pull/1254) tobyck
- Vyxal's infinite list support has greatly improved - the interpreter can now tell the difference between infinite and finite lists, opening the door to a lot of possibilities. [Thanks to](https://github.com/Vyxal/Vyxal/pull/1274) Steffan153 for this!

Bug fixes
- `Ǒ` (multiplicity) now checks for 0 and 1, [thanks to](https://github.com/Vyxal/Vyxal/pull/1245) cgccuser
- Floor (`⌊`) has been fixed twice [by](https://github.com/Vyxal/Vyxal/pull/1263) Steffan153 and [by](https://github.com/Vyxal/Vyxal/pull/1255) SE-Nitro
- Untruth (`Þǔ`) has been fixed [thanks to](https://github.com/Vyxal/Vyxal/pull/1264) Steffan153
- An old, bizarre bug where strings were printed without quotes has been fixed [by](https://github.com/Vyxal/Vyxal/pull/1259) Steffan153
- Yet another lazylist mutation bug has been patched, where negatively indexing into a lazylist used to append to itself, [thanks to ](https://github.com/Vyxal/Vyxal/pull/1262) Steffan153
- `⁺`, which decodes the next character as a number, now works with all chars [thanks to (https://github.com/Vyxal/Vyxal/pull/1275) Steffan153]
* `∆F`, 1-indexed fibonacci, now vectorizes properly [thanks to](https://github.com/Vyxal/Vyxal/pull/1271) Steffan153

Online interpreter

- The online interpreter now has a better search function. It now uses fuzzy pattern matching and sorts by closeness. [Thanks to](https://github.com/Vyxal/Vyxal/pull/1249) cjquines for this!
- The keyboard tooltips now have buttons you can click to insert digraphs, [thanks to](https://github.com/Vyxal/Vyxal/pull/1257) Steffan153
- The search function now highlights search results [thanks to](https://github.com/Vyxal/Vyxal/pull/1260) cjquines
- You can now use tab completions for unicode chars on the online interpreter, where pairs of characters will get resolved to single characters by pressing tab. For example, `.o` becomes `ȯ`, `bp` becomes `Þ`. [Thanks to](https://github.com/Vyxal/Vyxal/pull/1265) Steffan153 for this!
