+# Release 3.2.0 - (unreleased)
+
+ * libsecp256k1: to speed up elliptic curve operations, Electrum can now
+   utilize the libsecp256k1 library from Bitcoin Core, if present.
+   Otherwise, as before, python-ecdsa is used. libsecp256k1 is
+   bundled in the Windows, MacOS, and Android binaries. As we only
+   distribute source for Linux, for now, users need to install the library
+   themselves if they desire its benefits.
+ * Two-factor wallets are now implemented for Android.
+   Note that they only provide additional security if the one time
+   passwords are generated on a separate device.
+ * Semi-automated crash reporting is now implemented for Android too.
+ * Generalized local transactions: an "is mine" input is no longer needed 
+   to qualify as local, which in practice means that any transaction
+   that drops from the mempool becomes local and is kept. Previously
+   these were deleted from the wallet.
+ * Wallet logic: the scriptSig and witness part of transactions is no longer
+   parsed, unless actually needed, which was in the past occasionally the cause
+   of getting stuck in infinite "Synchronizing". As the input scripts are not
+   parsed, the "from" addresses are not inferred. The wallet history and
+   balance logic no longer depend on "from" addresses.
+   Perhaps most noticeably, as parent transactions are not fetched, and guesses
+   for the "from" addresses are no longer made, the Qt GUI will not display
+   addresses corresponding to the inputs (except for "is mine" inputs).
+ * The partial transaction format has been incompatibly changed. This was
+   needed as for partial transactions the scriptSig/witness has to be parsed,
+   but for signed transactions we did not want to do the parsing.
+   Users should make sure that all instances of Electrum they use to co-sign
+   or offline sign, are updated together.
+ * Signing of partial transactions created with online imported addresses
+   wallets now supports significantly more setups. Previously only
+   online p2pkh address + offline WIF was supported.
+   Now the following setups are all supported:
+   - online {p2pkh, p2wpkh-p2sh, p2wpkh} address + offline WIF,
+   - online {p2pkh, p2wpkh-p2sh, p2wpkh} address + offline seed/xprv,
+   - online {p2sh, p2wsh-p2sh, p2wsh}-multisig address + offline seeds/xprvs
+     (potentially distributed among several different machines)
+   Note that for the online address + offline HD secret case, you need the
+   offline wallet to recognize the address (i.e. within gap limit).
+   Having an xpub on the online machine is still the recommended setup, as this
+   allows the online machine to generate new addresses on demand.
+ * Ledger: offline signing for segwit inputs (#3302)
+   This has already worked for Trezor and Digital Bitbox. Offline segwit
+   signing can be combined with online imported addresses wallets.
+ * Added Revealer plugin. ( https://revealer.cc )
+   Revealer is a seed phrase back-up solution. It allows you to create a cold,
+   analog, multi-factor backup of your wallet seeds, or of any arbitrary
+   secret. The Revealer utilizes a transparent plastic visual one time pad.
+ * Fractional fee rates: the Qt GUI now displays fee rates with 0.1 sat/byte
+   precision, and also allows this same resolution in the Send tab.
+ * Hardware wallets: a "show address" button is now displayed in the Receive
+   tab of the Qt GUI. (#4316)
+ * Trezor One: implemented advanced/matrix recovery (#4329)
+ * Qt/Kivy: added "sat" as optional base unit
+ * Kivy GUI: significant performance improvements when displaying history and
+   address list of large wallets; and transaction dialog of large transactions
+ * Windows: use dnspython to resolve dns instead of socket.getaddrinfo (#4422)
+ * importing minikeys: use uncompressed pubkey instead of compressed (#4384)
+ * SPV proofs: check inner nodes not to be valid transactions (#4436)
+ * Qt GUI: there is now an optional "dark" theme (#4461)
+ * Several other minor bugfixes and usability improvements.
