Synapse 0.99.3.2 (2019-05-03)
=============================
Internal Changes
----------------
- Ensure that we have `urllib3` <1.25, to resolve incompatibility with `requests`. ([\#5135](https://github.com/matrix-org/synapse/issues/5135))
Synapse 0.99.3.1 (2019-05-03)
=============================
Security update
---------------
This release includes two security fixes:
- Switch to using a cryptographically-secure random number generator for token strings, ensuring they cannot be predicted by an attacker. Thanks to @opnsec for identifying and responsibly disclosing this issue! ([\#5133](https://github.com/matrix-org/synapse/issues/5133))
- Blacklist 0.0.0.0 and :: by default for URL previews. Thanks to @opnsec for identifying and responsibly disclosing this issue too! ([\#5134](https://github.com/matrix-org/synapse/issues/5134))
Synapse 0.99.3 (2019-04-01)
===========================
