A side-by-side editorial comparison of Dropbox Sign and Readwise — release velocity, themes, recent moves, and the top alternatives to consider.
Dropbox Sign's changelog has slowed to a trickle of API limits and field notes.
Dropbox Sign is an e-signature service sold primarily through its API, and this feed is the developer changelog rather than a product one. Activity is sparse: two entries in 2026 to date, both small — a validation-bypass flag for text tag extraction, and a raised ceiling of 100 files per signature request. The one substantive item is older, a redesigned mobile web signing experience being rolled out gradually to API plans starting with Essentials.
Two big swings in July and August, and since then Readwise has been paying the bill.
Readwise shipped a full mobile rewrite in late July and library-wide Ghostreader a fortnight later, and the weekly changelogs since have been almost entirely repair. The August 28 week is typical: thirteen fixes against five real improvements, spread across EPUB handling, chart and video embeds, Ghostreader chat on both mobile platforms, and Boox e-ink devices. The one consistent addition each week is parsing coverage for more publishers.

What is visible here is a mature API in maintenance: limits raised when customers hit them, response fields added when integrators need to branch on them, documentation corrected when it misleads. The signer app redesign is the only entry that touches what an end user sees, and it has been rolling out slowly since January rather than shipping as a release. Nothing in this feed suggests a change of direction.
The Signer App rollout is the only open thread with a stated plan — expansion beyond Essentials API plans is the most likely next entry, though this changelog is too sparse to read a roadmap from.

The fix list is a map of where the rewrite is still settling — pagination and layout stability on Android tablets, chat sheets and message sending on mobile, exports arriving with page CSS attached. Underneath that, small capabilities keep arriving quietly: Apple Books folder-EPUBs now upload, interactive charts render as linked images instead of an import notice, non-Latin titles survive the trip to Kindle. The company is broadening what it can ingest and export while stabilising what it rebuilt.
Expect the weekly cadence to hold with fixes still outnumbering additions, and the remaining Boox and Android tablet issues to keep appearing until the mobile rewrite fully settles.
