+# Acra ChangeLog
+
+
+## [0.76](https://github.com/cossacklabs/acra/releases/tag/0.76), March 9th 2018
+
+
+_Core_:
+
+- **SSL / TLS support**
+
+Now you can use PostgeSQL with SSL/TLS settings enabled. Acra supports two modes of connection between AcraServer and the database: using SSL/TLS or using Secure Session ([#113](https://github.com/cossacklabs/acra/pull/113), [#119](https://github.com/cossacklabs/acra/pull/119)).
+
+
+- **Unix sockets**
+
+Acra now supports usage of both TCP and Unix Sockets as a connection layer between AcraWriter <-> AcraProxy <-> AcraServer.
+
+- **Tests**
+
+	- Updated integration test suit to support multiple connection modes between the Acra components and the database ([#115](https://github.com/cossacklabs/acra/pull/115), [#117](https://github.com/cossacklabs/acra/pull/117), [#118](https://github.com/cossacklabs/acra/pull/118), [#120](https://github.com/cossacklabs/acra/pull/120)).
+	- Added Docker image to make testing easier ([#104](https://github.com/cossacklabs/acra/pull/104)).
+
+
+_Infrastructure_:
+
+- Added support of Go 1.10, removed support of older Go versions (<1.6).
+- Added support of Ubuntu 17.10, Ubuntu 16.04, Ubuntu 14.04, Debian Stretch.
+- Updated dependency libraries (libthemis and libcrypto) to use the latest ones.
+
+
+_Documentation_:
+
+- Updated the documentation and tutorials to reflect the latest changes.
+
+
+## [0.75](https://github.com/cossacklabs/acra/releases/tag/0.75), March 7th 2017
+
+This is the initial public release of Acra, a database protection suite.
+
+This version of Acra:
+
+- works on Ubuntu, CentOS, Debian linuxes
+- supports PostgreSQL 9.4+
+- has AcraWriter packages for Python, PHP, Go and NodeJS

 ## What is Acra

 Acra gives you means to encrypt the data on the application's side into a special cryptographic container, and store it in the database and then decrypt in secure compartmented area (separate virtual machine/container). Cryptographic design ensures that no secret (password, key, anything) leaked from the application or database is sufficient for decryption of the protected data chunks that originate from it. 
 
 Acra was built with specific user experiences in mind: 
+
 - **quick and easy integration** of security instrumentation.
 - **cryptographic protection** of data in the threat model where **all other parts of the infrastructure could be compromised**, and if AcraServer isn't compromised, the data is safe. 
 - **proper abstraction** of all cryptographic processes: you're safe from the risk of choosing the wrong key length or algorithm padding.

 The typical workflow looks like this:

 - The app encrypts some data using AcraWriter, generating AcraStruct with AcraServer public key, and updates the database. 
 - The app sends SQL request through AcraProxy, which forwards it to AcraServer, AcraServer forwards it to the database. 
 - Upon receiving the answer, AcraServer tries to detect encrypted envelopes (AcraStructs). If it succeeds, AcraServer decrypts payload and replaces them with plaintext answer, which is then returned to AcraProxy over a secure channel.
