Every release, with dates and details. Inkiostro is actively developed: version 1.8.0 shipped on 20 August 2026. That is 17 releases since the first one in September 2025.
Version history that gives back a single paragraph
Version history used to offer one thing: put the whole document back the way it was. That is the right tool for a disaster and the wrong one for a Tuesday, when what you want is the paragraph you deleted this morning. Now the history shows your changes one at a time, and each one has its own button.
Version history
Restore one change at a time: the history splits the difference between a version and your document into individual changes, each with its own button. Bring back the deleted paragraph, undo the rewrite, and everything you did afterwards stays exactly where it is.
Restoring is no longer a one-way door. Before anything is replaced, what you have right now is saved as a version — so if you bring back the wrong paragraph, the one you had is a tap away.
Versions follow the document. Rename it, move it to another folder, or let the app name it from your first heading: the history comes along. Before, it silently started over.
Versions are grouped by day and each says how much it changed before you open it. The unchanged text between one change and the next is folded away, because in a comparison what matters is what moved.
The count is visible while you write: a small clock in the editor tells you how many versions you have. It was the strongest thing in the app and nobody knew it was there.
On Mac the comparison window resizes, and you can walk the list with the arrow keys.
Writing
Tables, rebuilt. Pick the size by dragging across a grid instead of tapping two counters, and the table arrives with real headings in place. Tab moves cell to cell and adds a row at the end, the columns realign as you type, and a Table menu adds or removes rows and columns and sets each column’s alignment.
The same table engine on Mac, iPhone and iPad, so a table built on one reads right on the other.
Formatting floats right above the keyboard on iPhone and iPad, where your thumbs already are. Settings › Editor › Formatting Bar puts the old fixed bar back.
On Mac the floating toolbar fits any window width and quietly hides while you type, coming back the moment you reach for the mouse. It stays with you in full screen too.
Getting text in
Inkiostro is in the iOS share sheet. Share a thought from Notes, a paragraph from a web page or a line from a scratchpad, and it becomes a document with the title already filled in and the text ready to edit.
On Mac it is in the Services menu: select text anywhere, right-click › Services › New Inkiostro Document, and it lands here named after its first line.
Under the surface
Steadier on iCloud. Every read, save, rename, move, delete and import now announces itself to iCloud and waits its turn. Fewer documents that vanish for a moment, and no more quiet overwrites while a file is syncing.
Inkiostro finally wears its own colours — the warm sand of the app’s name, instead of the green it inherited from Lettera. If you preferred the green: Settings › Theme › Lettera Classic.
Menus and buttons have been read through in all fourteen languages. A few of them said things nobody meant — in German the app offered to sell you a share instead of sharing your document.
Version 1.7.3
·iPhone, iPad & Mac
Start writing, not naming
A corrective release. Creating a document used to begin with a question — what do you want to call it? — which is the wrong question at the wrong moment. New documents now open instantly and name themselves from your first heading.
Creating and naming
A new document opens straight away, ready to type in. Inkiostro takes the real name from your first heading: write “# Meeting notes” and the document is called Meeting notes. Rename it yourself and Inkiostro stops guessing.
“New document” is a proper button with a label at the bottom of your library, instead of a small “+” in a corner.
Renaming a document while it was open left the tab pointing at a file that no longer existed, so reopening it gave you the same document twice. Tags, colours and per-document fonts were left behind on the old name. Both fixed, including for folders containing open documents.
The editor
On iPad some documents opened completely flat — no headings, no bold, no links — until you started typing. Formatting now appears the moment a document opens and survives rotation, Split View and Stage Manager, across the whole document rather than just the visible part.
A table of contents on iPhone and iPad: every heading in the document, tap to jump, with the heading you are writing in highlighted. It used to be Mac-only.
Return inside a nested list kept dropping the new item back to the left margin. It now keeps the indentation.
Tab from the last cell of a table jumped into the next table further down the document; it now adds a row to the table you are in. Adding a row no longer produces one column too many.
Selecting several lines and pressing “bullet list”, “quote” or a heading level changed only the first one. It now changes all of them, and pressing again turns them all back.
Library and exports
“Group by tag” was a menu entry that did nothing on Mac. It now groups your documents by tag, with untagged ones in their own group at the end.
Filtering by tag used to hide folders as well as documents, which emptied the sidebar. Folders now stay visible.
EPUB: images were referenced but never included, so an exported book opened with no pictures and nothing said so. Images now travel inside the file, and documents with maths and diagrams pass validation.
HTML: an exported file said it used Lexend but did not carry it, so on someone else’s computer it silently arrived in a different typeface. The font now travels inside the file.
Documents containing Mermaid diagrams no longer mis-measure their own outline, so jumping to a heading lands where it says it will.
Version 1.7.0
·iPhone, iPad & Mac
A real Mac app, not a Catalyst build
The Mac version stopped being an iPad app in a window. It moved to its own project and became a native macOS app, sharing the document format and iCloud container with iPhone and iPad but built for the Mac.
Mac
Native macOS app, split out of the iOS project — Mac Catalyst was removed in 1.6.1.
The Mac app ships from its own codebase and tracks the same version numbers as iPhone and iPad from here on.

This release
Renamed from Lettera to Inkiostro, with new App Store metadata.
The editor moved to TextKit 2. Syntax highlighting is now immediate — headings no longer lag behind what you type.

Earlier releases
These shipped too. They pre-date the point where we started keeping written release notes, and rather than describe them from memory we list them as they are: a version number and the day it went to review.
